Implementation and evaluation of "Three Preventions" in rainy season in 2009

rules and regulations

In order to conscientiously implement the "Notice on Doing a Good Job of" Three Preventions "in the Rainy Season in 2009" (An Zi [2009]), do a good job of "three preventions" in the rainy season and ensure the safety of the mine during the flood season, combined with the actual situation of the mine, the specific implementation and assessment management methods of "three preventions" in the rainy season of the mine are formulated.

I. Implementation opinions

1, firmly establish the idea of "safety first, production second", further improve the understanding of "three defenses" in rainy season, base on flood control and flood fighting, earnestly grasp the reserve of flood control materials and the implementation of flood control projects in rainy season, and ensure that key projects are completed on schedule.

2, during the rainy season to strengthen the mine surface water system, collapse, spot crack, water area and the surrounding environment and transmission lines inspection, inspection, especially in rainy days, after the rain, found the problem, report in time.

3, strengthen the observation of mine water inflow in flood season, all kinds of waterproof facilities and waterproof coal pillar investigation, do a good job in the maintenance of drainage and drainage system, responsibility to people, and incorporated into the dispatching management. For places threatened by hidden dangers of water disasters, production should be organized in strict accordance with the principle of "forecasting, suspicious exploration, exploration before excavation, treatment before mining" to ensure mine safety in flood season.

4. Establish a regular flood investigation system. To strengthen the management of underground waterproof facilities and water accumulation in production areas, it is necessary to blame people. The chief engineer is responsible for immediately organizing a comprehensive special investigation of water regime and water disasters, and setting personnel, measures and standards to rectify the problems found within a time limit; At least once a month, conduct a comprehensive flood investigation in and under the well, strictly implement the responsibility system for governance, and ensure the "five implementations" of the project, engineering quantity, funds, construction personnel and completion (completion) time. The chief engineer is responsible for organizing the acceptance after the rectification of major water hazards is completed.

5. According to the actual situation of the mine, the chief engineer is responsible for formulating perfect flood control measures and emergency plans, which should include command and dispatch, power supply load control and power transmission procedures, pump starting sequence, coordination of pump houses at all levels and cooperation of drain pumps, closing sequence of water distribution gates, evacuation routes, disaster identification, accident rescue, etc., and resolutely ensure that the rainstorm does not flood the well and does not hurt people. The key monitoring mining areas threatened by water disasters should have targeted emergency plans. In the rainy season, it is forbidden for production or personnel to enter areas seriously threatened by water.

6, to further strengthen the investigation of adjacent local coal mines. The chief engineer of the mine is responsible for organizing personnel to conduct a comprehensive investigation on the mining dynamics, the upper and lower limits of mining, the water accumulation in the mined-out areas in the adjacent places, whether there is overlying rock and the destruction of various waterproof coal (rock) pillars, analyze the threat of water disasters to the mine, and report and deal with problems in time. Investigators should carry questionnaires, implement the on-site signature system, and investigate according to the requirements of who investigates, who signs and who is responsible. Due to the irresponsible investigation of investigators, they failed to find out problems such as overburdening or destroying isolated coal (rock) pillars in time, which caused potential safety hazards. Investigators and related personnel should be held accountable.

7, by the chief engineer is responsible for emergency measures, including the prevention and treatment of adjacent mines, as well as the withdrawal of production in bad weather. To study the waterproof scheme, set up a flood control team and conduct a disaster relief drill before June 10.

8, according to the actual mine to do a good job of mechanical and electrical safety in the rainy season, the mine power supply system, drainage system, communication system to conduct a comprehensive inspection and testing, and equipped with enough spare parts. The joint trial operation of mine main drainage system must be completed before May 30th to ensure it is in good condition. By the mechanical and electrical mine manager.

9. Investigate the 6KV and 35KV lines under its jurisdiction one by one, and deal with the problems that affect the safe operation of the lines in combination with the spring line cleaning, especially the obstacles such as trees and buildings in the safe passage of the lines, and thoroughly remove them to ensure reliable power supply for the loads such as mine power lines and ground step-down stations.

10, complete the cleaning and excavation of the water bunker on time, clear and dredge the drainage ditch in time, check and maintain waterproof facilities such as waterproof gates, and vacate a water bunker as a buffer at the level of -300 and -530 in rainy season. By the tunneling manager, mechanical and electrical mine manager.

1 1, lightning protection devices of ground buildings, power distribution stations, power supply lines, derricks and other facilities must be inspected and tested, complete and effective; Main transformer and main cable shall be tested and calibrated according to regulations to ensure sensitivity and reliability. By the mechanical and electrical mine manager.

12, pump room, substation and other important places should be equipped with personnel on duty, hold relevant certificates, and report and feedback relevant information in time.

13, strictly implement the system of stopping production and withdrawing people in disaster weather. When the continuous rainfall reaches more than 50mm or the weather forecast is "rainstorm", the main person in charge of the mine, the mine leaders in charge of safety production, the professional leaders, the deputy section chief (director) of the department, the mechanical and electrical department, the dispatching room, the geological survey department, the workers' and peasants' room, and the public security units must be on duty to start "stopping production and evacuating people in severe weather", otherwise each vacant post will be fined 100 yuan, which will affect flood control and disaster relief.

14, set up Dawen River hydrological observation station to master the hydrological conditions such as river flow and water level, and designate a special person to know the flood discharge information of the reservoir from the water conservancy department and observe the change of river water level in time, so as to take corresponding measures in advance when the reservoir discharges flood and the river water level is abnormal. Arrange special personnel to inspect the banks along the river during the rainstorm, and handle the problems in time when they are found.

15, the key projects of the group company and the cleaning and excavation of the main horizontal pool must be completed before May 30th, and the acceptance system shall be strictly implemented. Self-inspection shall be carried out by the mine first, and the group company shall check and accept one by one. After it is determined that the main horizontal water storage tank that does not need to be excavated is drained, special personnel shall be arranged to check the siltation and deformation of the water storage tank and sign for acceptance. For the key projects listed in the mine, the data shall be kept for future reference after being signed by the leading organization in charge of the mine item by item. The general project of "Three Preventions" in rainy season shall be checked and accepted by the mine, and the data shall be kept for spot check by the group company.

16. before the rainy season comes, improve the construction of "three lines" and inspect and repair compressed air pipelines, dust-proof pipelines and communication lines.

17. During the rainy season, the "Three Preventions" duty starts from June 10 to September 30th, during which the "Three Preventions" office is manned 24 hours a day, so as to timely dispatch and coordinate related matters and make records. The leading group and flood control emergency personnel take turns to be on duty, and strictly implement the 24-hour duty system in rainy season.
