Scientific and Technological Innovation and Corporate Culture in Panxi Coal Mine

Adhere to the people-oriented concept, pay attention to the construction of corporate culture, determine the "chief technician" and the "title system" of scientific and technological innovation through the selection of "enterprise star" and "technical expert", create a good environment for employees to become talents, and form a distinctive corporate culture. Panxi Coal Mine of Xinwen Mining Group was built in 1958. Since 1960 was put into production, the annual production capacity is only 300,000 tons. After the reconstruction and expansion of 1992, the annual production capacity reaches 600,000 tons.

Since 200 1, the annual production capacity of the mine has reached 1 10,000 tons by organizing and implementing the strategy of developing the mine through science and technology. With the commissioning of the auxiliary hoisting system, the actual production capacity of the mine can reach10.2 million tons per year. In recent years, the mine has actively implemented four innovations in management, system, technology and ideological and political work, and the mine has achieved leap-forward development, showing vigorous development vitality, and the raw coal output and economic benefits have increased year by year. In 2002, the output reached 6.5438+0.8 million tons and the profit was 30.94 million yuan. In 2003, the output reached 654.38+0.10.8 million tons, with a profit of 59.63 million yuan. From June to September this year, the output of safe coal reached 910.8 million tons, with a profit of 35.38 million yuan.

In recent years, Panxi Coal Mine has been successively rated as a high-yield and high-efficiency mine in coal industry, a standardized mine for coal quality management, a contract-abiding enterprise in Shandong Province, an award-winning unit of Shandong Coal Industry Bureau, a ventilation model mine, an advanced unit for measurement management in Shandong Province, an advanced unit in Laiwu City, a civilized unit in Laiwu City and a garden-style unit. It has passed the confirmation of ISO 100 12 measurement assurance system and the certification of ISO900 1 quality management system, and obtained the product inspection exemption certificates of "Top Ten" coal mines with national scientific and technological progress, field management demonstration enterprises in Shandong Province, "Top Ten reputable coal mines" in 2002: AAA grade, Top Ten coal mines with scientific and technological progress in coal industry, and Shandong Provincial Bureau of Quality and Technical Supervision. And realized the continuous safe production 1808 days, and the safe coal production was 5.28 million tons. In July 2000, Director Lu Guangming took office, and he was under great pressure. With the increase of mining life, the mine pressure increases year by year. Mine water, fire, gas, coal dust, roof and rock burst are all toxic, and the ventilation system, power supply system, transportation system and drainage system are full of difficulties and obstacles. Some facilities are out of service, and the bearing capacity of ventilation system is insufficient, which seriously restricts the safe production of mine.

After careful consideration, Lu Guangming, the mine manager, began to carry out "major surgery" on the mine, deepened the reform, laid the strategic commanding heights with advanced productive forces, and laid the cornerstone of enterprise development with the power of science and technology.

-Technological innovation boosts enterprise development. The mine has implemented the responsibility system for innovative projects, the assessment and reward system for reform and rationalization suggestions, quantified innovative projects to the head, infiltrated innovation into every link of production and operation, and maximized the role of technological innovation in reducing production input and improving labor efficiency. Industry-University-Research cooperation has been strengthened, and a number of difficult problems affecting mine safety production have been solved.

-Auger-drilling unmanned face mining technology fills the gap in China. Under the guidance of the group company, Panxi Coal Mine took the lead in introducing Ukrainian Baishi -2 spiral shearer into the national coal system. This technology adopts digging before mining and mining up and down along the coal seam. All seven workers in each shift work in the transportation lane, and some gangue can be backfilled to the lower part of the hole. "It is suitable for extremely thin coal seams that cannot be mined by traditional coal mining technology in China at present, which makes the recovery rate of thin coal seams reach 80% from 30%, and has been demonstrated by experts such as academicians of the two academies. Achieved the effect of "three highs and four lows": high safety factor, high labor efficiency and high return on investment; Less people, less equipment, less system links and less material consumption.

-A trackless rubber-tyred vehicle was used. WCD-3B trackless rubber-tyred vehicle jointly developed by Panxi Mine and Changzhou Research and Test Center has the characteristics of compact structure, convenient operation, small turning radius, strong climbing ability and little pollution. The unloading chute of scraper was lengthened and heightened in Panxi Coal Mine, and the fixing mode was changed from supporting type to hanging type, so that the carriage of rubber-tyred truck entered from below the scraper and directly received the truck, which eliminated the phenomenon of front-end accumulation and scattering of gangue when the scraper was unloaded, improved the efficiency, and made the large-section roadway of 12 square meter enter 40 meters more every month than when the battery truck was hauled and transported.

The drainage technology of kilometer vertical shaft ranks first in China. The natural water inflow in Panxi Mine is large, and the original three-stage drainage system has been unable to adapt to the expansion of mine scale and waterproof and disaster-resistant ability, resulting in a lot of waste of manpower, material resources and financial resources. The annual drainage fee alone is as high as180,000 yuan. In order to change this situation, Panxi Coal Mine has carried out the research and application of the drainage technology of 1000-meter vertical shaft, and learned from others. From design to construction, quality inspection to safety measures, the best is selected. Imported high-flow and high-lift pumps are used to directly discharge the water with the level of -740 to the ground, and the lift 1079.7 meters is the highest in China. Since the successful operation of the system on June 18, 2002, the drainage cost has been saved by nearly 2.7 million yuan, which has improved the economic benefits of the mine. At the same time, the application of this drainage technology has greatly enhanced the mine drainage disaster resistance and provided a strong guarantee for safe production.

-Industry-University-Research. Panxi Mine, together with China University of Mining and Technology, Shandong University of Science and Technology and other scientific research institutions, has carried out the research and application of more than 80 technical achievements 180, such as key technologies with high difficulty, high yield and high efficiency, prevention and control of coal dust explosion and gas control, comprehensive control technology of Ordovician limestone water in mines, zero defect management, value management and safety informatization, among which 34 have reached the domestic leading level.

In the transformation of power supply system, the 35KV power supply line was changed from Laiwu Bridge 1 10KV step-down station to Laiwu Qishan 220KV step-down station. Through transformation and treatment, the problem of insufficient power supply in the mine is solved, which provides a strong power for the safe operation of the mine. At the same time, the power supply system of 6/4KV electric lighting was reformed, and the energy-saving transformer was put into operation. According to the optimized operation mode, the step-down station, No.1 well, auxiliary well and Gongrencun substation have high power consumption transformers, but they are only used as cold standby. Therefore, all seven power distribution stations use energy-saving transformers. After calculation, the annual operation loss of transformers in the optimized seven distribution stations is 57 1 16KWh, and the annual electricity consumption is 25,702.20 yuan, which is 5536 kWh less than that before optimization, and the annual electricity consumption is 249 12.45 yuan, which has achieved good economic benefits.

The floor of Panxi Coal Mine 19 coal seam is 60m away from Ordovician limestone. With the increase of mining depth, the Ordovician limestone water pressure increases, there are many faults in the mine field, structural cracks develop, and the floor often gushes water during mining, which poses a great threat to mine safety production. Facing the danger, they built 26 Ordovician limestone hydrological observation wells underground, analyzed the water-rich characteristics and water inrush mechanism of Ordovician limestone, and studied and formulated water prevention measures to ensure safe production. Safety innovation tamps the development foundation.

Since the construction of Panxi Mine, blasting mining and high-grade conventional mining have been used, which have high labor intensity, low labor efficiency and low safety factor. To this end, actively explore the use of new technologies and new equipment. First, the application of fully mechanized mining technology with large dip angle. In the process of installation and use, in view of the present situation of large dip angle of coal seam, nearly 20 preventive measures have been taken successively, such as connecting the top support, injecting liquid into the lower support, installing anti-falling devices in different areas, strictly operating procedures, adjusting the false dip angle in time, and keeping the jack vertical to the conveyor. The normal advance of the working face is ensured. The coal output in the first month was 80,600 tons, and the raw coal output in five months reached more than 80,000 tons. More than ten hidden dangers such as roof, spalling, blasting, pillar, retreat and spontaneous combustion have been reduced or eliminated, and all kinds of accidents have been put an end to. The second is the application of a fully mechanized excavator. On the basis of full investigation and demonstration, in February last year, S191auxiliary roadway was used for the first time. After three months of test, good results have been achieved, which have been used in 7 19 1 main lane, 432 transport lane and 4 196 auxiliary lane. And gradually explore the comprehensive excavation support technology of large dip angle coal roadway, the average single entry level exceeds 400 meters, which is 2.5 times that of blasting excavation; The cost is lower than that of blasting excavation 143 yuan/m, and each machine can save 600,000 yuan in material cost every year.
