Four sets are installed in the upper and lower lanes of 30101 respectively, and 3 sets are installed at the liaison offices of the three main lanes, totaling 11 sets. In the next step of the excavation of the working face, this equipment needs to be installed on the excavation working face.

5. The water supply rescue system has also been built accordingly, and the installation location is the same as the pressure wind self-rescue device.

6. The emergency avoidance system is still being implemented, and the rescue cabin has not yet been ordered. .

2. Adhere to intrinsic safety and achieve an overall good safety situation throughout the year

20xx is a critical year for Liuxiang Coal Mine to inherit the past and usher in the future. It adheres to the policy of "safety first, prevention first" In accordance with the policy, we adhere to starting from basic work and unremittingly focus on on-site safety management, achieving an overall good safety situation throughout the year. There were 0,000 minor injuries, 00 minor injuries, and 44 "three violations" were detected throughout the year.

1. Establish and improve the organizational structure. After the Liuxiang Coal Mine was established in April, we established a technical department, a safety department, and a ventilation area based on the actual needs of the site, and equipped them with relevant special types of work and management technicians; we also improved basic units such as the mechanical and electrical area, transportation area, and excavation area one and two. The organizational structure and management personnel are equipped; currently, all institutions can operate effectively and give full play to their due functions. The newly assigned college students and technical school students have greatly filled the shortage of technical personnel, and all work is carried out in an orderly manner.

2. Carry out safety publicity and education activities. Before putting into production, a safety work meeting was held, and 12 safety office meetings, 15 special safety management meetings, and 0,000 scheduling meetings were held throughout the year; June safety month activities, "Ankang Cup" competition activities, and learning were organized and implemented. The Shenhua Spirit, the “12.8” Safety Warning Education Conference, etc. have created a good safety education environment.

3. Develop safety rules and regulations. Guiding documents such as Liuxiang Coal Mine No. 1 "Safety Work Opinions in 20xx", No. 2 "Liuxiang Coal Mine Safety Management Regulations in 20xx" and "Measures for the Assessment of Managerial Personnel Safety Non-Performance" have been formulated; according to Liuxiang Coal Mine Safety Due to the particularity of production, the "Management System for Ground Cranes and Underground Changing Chamber Cranes", "Dust Prevention and Control Management System", "Water Prevention and Control Management System", "Rubber Wheel Vehicle Use Management System", "Liuxiang Coal Mine Management systems such as "Fire Protection Management Regulations", "Formulation of Inclined Lane Transportation Management Regulations", "Pedestrian and Vehicle Operation Management Regulations", "Liuxiang Coal Mine Safety Production Operation License Management System", etc., divide safety work into departments, teams and groups. Individuals have formed a target management and assessment mechanism that focuses on safety production and management.

4. Strengthen safety supervision and inspection. Comprehensively implement the production safety responsibility system, strengthen on-site safety management, and organize various forms of supervision and inspection regularly and irregularly.

In 20xx, *** organized 32 safety and quality inspections, 10 special inspections for ventilation, 24 special inspections for mechanical and electrical, and cooperated with 14 inspections everywhere. *** produced 175 hidden dangers, all of which were rectified; we welcomed 8 inspections of Huaneng Coal Industry This time, 68 hidden dangers of various types were investigated. After inspection and follow-up organized by the Safety Supervision Department, the rectification rate of various hidden dangers reached 96%. Adhering to the principle of strictness and severity, and adopting a combination of punishment and education, 44 people of various types of "three violations" were detected during the year. Through help and education, they were able to standardize their operations and work safely, effectively curbing the occurrence of accidents and achieving the goal of The purpose of safety education.

5. Focus on supervising and controlling weak links. Inclined tunnel transportation is the focus of safety management and control in our mine. We have strengthened the inspection and maintenance of the anti-road vehicle devices in auxiliary shafts, and contacted the manufacturer for multiple debugging and improvement of the anti-road vehicle devices. The Safety Supervision Department tracks and supervises daily rope inspections, pedestrian vehicle inspections, etc. Work; During the initial topping-out of 30101, 24-hour dynamic monitoring of the working resistance of the working face support and the advance support tunnel ensured the safe topping-out of the working face; the safety officers performed their duties and supervised and inspected all aspects of the work surface, thus preventing many accidents.

6. Pay close attention to the investigation and management of hidden dangers. We have successively organized and implemented the special action of "Cracking down on illegal activities" and the look back action, the June Safety Month activities, the Ankang Cup, etc., and carried out in-depth investigation and management of hidden dangers, and achieved obvious results. The number of hidden dangers has been reduced from more than 100 in January to More than 80 items.

7. Gradually form a systematic working procedure. Hidden hazard investigation has formed a closed-loop management, and rectifications have been implemented in a timely manner; "three violations" management has formed a complete management process and is being institutionalized; accident investigation is meticulous and thorough, and the combination of punishment and education is standardized; accident reporting procedures are clear and clear, and the deployment force responds quickly; inspection and maintenance Keep a ledger and keep records of key equipment.

3. Pay attention to learning and training to enhance the professional quality of employees.

In order to improve the safety quality of the entire mine's cadres and workers, enhance self-protection awareness, prevent and reduce various casualties, in accordance with the requirements of superiors and combined with the actual situation of the mine, we will train safety production management personnel and special equipment operations Focusing on the basic knowledge of production safety and on-site operation skills of management personnel, the entire year's training tasks were completed as planned, which improved talent security and intellectual support for promoting production safety in our mine and creating an intrinsically safe mine.

1. Strengthen the organizational leadership of safety training. By hiring part-time teachers, the effect of safety training has been strengthened, safety training work has been incorporated into the integrated management of coal mine safety production, and the leadership responsibility system and target responsibility system for safety training have been strengthened and improved; 5 deputy mine managers have participated in the training courses in phases.

2. Make every effort to organize training for all employees. Every time a new employee joins the mine, pre-job training is given carefully and meticulously to enable them to master safety knowledge and on-site operation skills, and to enhance the safety awareness of employees. Currently, there are 258 people with certificates for special types of work in the mine, and 25 people with management personnel have certificates, which basically meets the requirements. Require. Completed training for 13 newly assigned college students, 4 technical school students and several batches of new miners.

3. Do a good job in the review and retraining of expired certificates. Full-time safety inspectors, section chiefs, engineering and technical personnel, special operations personnel, and general and special operations personnel who have transferred, changed, or returned to work after being away from work for more than one year need to participate in refresher training and training.

IV. Strictly focus on project quality and strive to create high-quality highlight projects

1. Completed all excavation tasks for the main water tank, accurately connected the main water tank and the main pump room, and completed the nailing The duct is currently being poured;

2. The north wing return air alley and the return air duct of the panel substation have been safely and accurately connected to form a complete ventilation system;

3 , 5 water detection eyes have been completed for the roof water exploration of the 30101 working face, and the construction of the sixth eye is currently underway;

4. The hydraulic fracturing control technology of the hard top coal roof has achieved the expected results. Due to the drilling With scientific layout and strict construction, the lithology of the roof has weakened over a period of time. As the working face moves forward, supplemented by the effect of mine pressure, cracks appear regularly in the direct roof and the old roof, and gradually collapse, and the working face The pressure in front of the coal wall is reduced, ensuring the safety of the working face.

5. The lighting project has been implemented in the main and auxiliary shafts, and explosion-proof lighting has been installed in the entire tunnel, which has improved the safety factor of driving and pedestrians in the inclined shaft, and also provided a good environment for normal maintenance. lighting conditions.

6. Explosion-proof iron doors are installed in the central substation and water pump room, and heaters are installed in the main and auxiliary shafts, which greatly improves the supporting facilities of the mine.

5. Strengthen technical management and standardize various procedures and systems

1. Strict approval system for operating procedures and safety technical measures: adopt a system of submitting operating procedures and safety technical measures for joint review in advance , comply with the measure approval procedures, and complete the measure approval and study communication work before starting work.

2. Hold regular technical meetings. By holding regular technical meetings and regular meetings on one-stop and three-prevention every month, we not only summarize the technical work of the previous month, but also arrange the work focus for the next month, which is conducive to identifying problems and proposing preventive measures, making the technical work forward-looking and instructive.

3. Completed the collection, sorting and archiving of data in strict accordance with technical management regulations. It ensures that each project has a complete data save for easy search, and strictly implements "one project, one measure" to eliminate the phenomenon of unmeasured construction.

4. Optimize layout and reasonably arrange production continuity. Before the start of production, we closely focused on the established joint trial operation goals of Liuxiang Coal Mine, accelerated the progress of the project, optimized the design and rational configuration, and carefully organized the construction. Especially during the shutdown period from March 26 to May 27, we carefully arranged all the work at the grassroots level. The unit strives to eliminate all unfavorable factors and actively organizes the installation of the 30101 working face, the installation of the main shaft belt, the laying of various system pipelines and various auxiliary projects above and below the mine, laying a good foundation for the mine to be put into production as soon as possible; after the production is put into operation, it will take over the overall situation and actively layout In the production continuation work of the entire mine, especially after the withdrawal of Huamei, the construction was scientifically organized and personnel were reasonably allocated, achieving a scientific and economical labor organization. After the work surface was suspended on October 16, we organized safety inspections in conjunction with various majors, and used the shutdown period to promptly rectify the identified problems. The design of the 30103 working surface has been completed and all follow-up work is in progress.

5. Actively promote the application of new technologies and new processes: (1) In view of the fact that the tunnel boring machine of our mine water tank produced a large amount of dust during excavation, which caused serious pollution to the workplace and had a negative impact on the health of employees. Serious harm (the dust removal device purchased by Party A is not effective), the original ventilation and dust removal system was transformed: from the original push-in ventilation to the pull-out type, which achieved better economic and social benefits; (2) Designed The comprehensive water utilization plan of the auxiliary well and wind well water allows the water from the auxiliary well to be introduced into the wind well ditch through an 82-meter borehole, and then into the reservoir, which solves the problem of water shortage and overcomes the problem of vertical and horizontal pipes at the lower outlet of the auxiliary well. The difficulties affecting driving operations have created huge safety and economic benefits for enterprises.

Although we have achieved regrettable achievements after a year of hard work, there are still many problems and deficiencies in our work. Basic safety work needs to be further strengthened, and the habitual violation of regulations by employees has not been eliminated. We need to seriously solve it in the new year. The core aspects include the following:

1. Main oblique The well belt conveyor lacks short belt protection, automatic sprinkler device, and dust reduction sprinkler device has not been formed.

2. Workers’ operating skills and safety awareness need to be improved, and training needs to be strengthened to improve the management level of talent and equipment in our mine.

3. The professional level of management personnel cannot meet the needs of modern high-yield and efficient mines. We are currently preparing to hold various training courses to improve work efficiency.

4. Various assessment and incentive mechanisms are not sound enough. Establish and improve a long-term competitive incentive mechanism, integrate competition activities into coal mine safety work, and stimulate the enthusiasm for work and independent innovation spirit of cadres and workers. Promote quality standardization and the creation of intrinsically safe mines.

5. There is a serious shortage of core technical talents. If key equipment fails, we can only contact the manufacturer for assistance. The shortage of technical talents seriously restricts the normal safe production of our mine.

Chapter 2:

This month, under the correct leadership of the company and with the strong support and help of various departments and units, I led all the employees of the Supply Department to unite, work together, and work diligently Work, complete all work tasks, and achieve good results. The work situation of this month is summarized as follows:

1. Focus on the center and strive to do a good job in supply work

Our mine’s first mine this month The equipment of working face 101101 fully mechanized mining face needs to be inspected and confirmed. I lead all the staff in the supply department to do their best to purchase the equipment and ensure that the equipment of the fully mechanized mining face is inspected and confirmed successfully. In the first ten days of this month, when there were few people and heavy tasks, I carefully planned the equipment procurement work, arranged it carefully, and implemented the tasks. I required each supplier to work hard and purchase equipment in time without affecting the installation progress of the fully mechanized mining surface equipment. Some equipment did not arrive in time in the middle of this month, which seriously affected the installation progress of the fully mechanized mining surface equipment. Under this situation, we actively contacted the suppliers and asked them to pay close attention to speed up the equipment production progress and send the equipment to our company on time. . In order to ensure the progress of the installation, we sent people to the factory twice to supervise them. Through our efforts, the equipment arrived in time and basically did not affect the installation of the 101101 fully mechanized mining face equipment. The installation work of the fully mechanized mining face equipment is coming to an end later this month, but the lack of some sporadic materials still seriously restricts the installation progress of the fully mechanized mining face equipment, such as some high-pressure hoses and lubricants used in the equipment. Under this circumstance, We handle special matters, collecting and sorting out the number of items that lack sporadic materials and reporting them to the company, while actively contacting suppliers to ensure that the missing sporadic materials arrive in a timely manner and minimize the impact on the installation progress of the fully mechanized mining surface equipment.

2. Work diligently and complete the warehouse inventory

Due to the installation of 101101 fully mechanized mining surface equipment this month, our tasks are heavy and the work is tense. Before the heavy work, we carry out warehouse inventory according to the company's requirements. In order to do a good job in the warehouse inventory, we held a meeting, studied company documents, and made careful and detailed arrangements on how to do a good job in the warehouse inventory. We required the inventory personnel to do a responsible job in the warehouse inventory and ensure that the accounts were consistent. , the accounts are consistent, and the accounts are consistent. After everyone's joint efforts and diligent work, we took stock of the inventory situation in the auxiliary well warehouse. The bulk materials in the main well warehouse have basically been accounted for, and the inventory was reported as scheduled on the 25th. While doing a good job in warehouse inventory, we have put forward new requirements for strengthening warehouse management and improving material management levels, striving to manage the warehouse better and contribute to the company's development.

This month I worked hard and diligently, completed all tasks and achieved good results. Next month is the first month for coal production at the 101101 fully mechanized mining face of our company. Under the correct leadership of the company and in accordance with the company’s work spirit and work arrangements, I will further inspire and motivate all employees of the supply department* **Work together to do all the work, provide production services for the company, and promote the healthy and rapid development of the company.
