New progress has been made in the construction of large-scale coal mines. “This line is the route you just walked down the well. You stay at what position, how long you stay, and there will be detailed records here.†Monitoring at China Shenhua Shendong Coal Mine Group, Shangwan Coal Mine In the room, the staff pointed to the monitor and told reporters.
Just an hour ago, the reporter had just experienced an underground interview. The staff told the reporter that this system for clearly describing the whereabouts is the downhole personnel and vehicle location monitoring system at Shangwan Coal Mine.
According to Wei Guangrong, Chief Engineer of Shangwan Coal Mine, in recent years, the Shangwan Coal Mine has accelerated the construction of a large-scale modern coal mine, and all the mine shafts have been equipped with advanced mining equipment for fully mechanized coal mining and continuous mining. The mechanization degree of mine excavation has reached 100%; each mine production The system realizes centralized control; it realizes automatic monitoring and monitoring. In 2008, the Shangwan Coal Mine completed 13.29 million tons of raw coal production, 12.5 million tons of commercial coal, and the mine's death rate of one million tons was “zeroâ€, achieving a goal of no casualties for 10 consecutive years.
Shangwan Coal Mine is an important microcosm of China's promotion of large-scale modern coal mine construction in recent years. Wang Xianzheng, president of the China Coal Industry Association, pointed out that accelerating the construction of large-scale modern coal mines is one of the most important tasks for China's coal industry to "adjust structure" and will surely promote the stable, healthy and sustainable development of China's coal industry.
"As of the end of 2008, China's safe and efficient mines (outdoors) had been developed from the original 12 pilot coal mines to 292, with a production of 860 million tons, accounting for 30.9% of the country's total production." Wang Xianzheng said that in recent years, with coal bases and The construction of large-scale coal enterprise groups continued to advance, and the national coal mine safety and high-efficiency mine construction continued to accelerate, and the proportion of production continued to increase, which effectively promoted the improvement of coal productivity in China and the overall improvement of the coal mine safety situation.
Wang Xianzheng told reporters that in the process of promoting the construction of safe and efficient mines, the coal industry has continuously summed up experiences and updated concepts, carried out targeted key technology research, effectively promoted the advancement of coal science and technology and management, and promoted China's large modern coal mines. With the construction, the production structure of the coal industry has been further optimized and the degree of industrial concentration has been further improved.
Relevant statistics show that there are currently 469 large-scale coal mines with an annual output of over 1.2 million tons (including construction and renovation and expansion of coal mines), accounting for less than 2.5% of the total coal mines in the country; output totals 1.423 billion tons, accounting for 53.14% of the country's total output. . In 2008, 95% of large-scale coal mining in the country reached 100% mechanization of coal mining, and annual per capita production efficiency reached 5,840 tons. In addition, the average coal mine death rate of 0.035 million tons, of which more than 10 million tons of coal mines to achieve zero deaths.
Wang Xianzheng said that at present, accelerating the construction of large-scale modern coal mines is of great significance to the restructuring of the coal industry, the promotion of industrial upgrading, the transformation of development methods, the improvement of development quality, and the coordination of economic and social development.
The timing of structural adjustment has matured. "From the current perspective, the task of structural adjustment of China's coal industry is still relatively heavy." Wang Xianzheng said that although China has built a large number of large modern coal mines with advanced international standards, Shenhua, China Coal, Datong, Shanxi Coking Coal Such large enterprise groups have grown rapidly. However, there are more than 18,000 various types of coal mines in the country with an average size of only 180,000 tons, and the low level of industrial concentration is very severe. The profit level of the coal industry has increased year by year, but it has been mainly concentrated in the top 20 companies. The vast majority of enterprises are still in a state of low profit. Large-scale state-owned coal enterprises have reached the international advanced level in technology, technology and equipment, and the mechanization of coal mining has reached more than 87%. However, the mechanization of coal mining in the entire industry is only about 45%. This is still a big gap with developed countries.
Therefore, the coal industry must accelerate the grasp of the important modern coal mine construction, accelerate the pace of structural adjustment in the coal industry, and further promote the transformation of development methods.
Wang Xianzheng told reporters that at present, China's coal industry is in the best period to accelerate structural adjustment.
On the one hand, the country’s coal industry has maintained a steady development trend since the country’s series of effective measures to “maintain growth, expand domestic demand, and adjust structureâ€. According to relevant data, in the first eight months of this year, the country's raw coal output was 1.875 billion tons, an increase of 9.7% year-on-year; coal sales were 1.738 billion tons, an increase of 6.46% year-on-year. In August, raw coal production was 260 million tons, up 14.6% year-on-year; coal sales were 241 million tons, an increase of 9.85% year-on-year. The total supply and demand of coal is basically balanced, and the situation of a slight supply of surplus creates a good atmosphere for the coal enterprises to control the total volume and adjust the production structure.
On the other hand, after years of development, China's coal industry has already met the conditions of technology, equipment, capital, and talent needed for "adjusting structure." In addition, some large-scale coal enterprises actively extend to other non-coal industries, and other industries and enterprises have begun to invest in the coal industry, which will provide new development ideas and beneficial explorations for how the coal industry will accelerate structural adjustment and change the mode of development.
Industry enterprises must pay close attention to the implementation of the reporter learned in the interview that the current China Coal Industry Association has initially drafted the guidance to accelerate the structural adjustment and promote the construction of large-scale modern coal mines.
According to relevant plans, by the end of 2015, the proportion of China's large-scale coal mines will reach more than 50%; the comprehensive recovery rate of mine coal resources will reach more than 50%, and the comprehensive recovery rate of open-pit mining coal resources will reach over 90%; the mechanization of coal mining will average 95 More than %, the degree of mechanization of fully-mechanized excavation reached more than 70%; the mortality rate of coal mine accidents was controlled to be less than 0.1; the rate of coal raw coal washing (selection) was 100%, and the mine water standard discharge and utilization rate was over 90%.
Wang Xianzheng said that at present, it is an important period for China's economic restructuring and transformation of development methods. It is also a critical period for the coal industry to accelerate structural adjustment and achieve scientific development. The coal industry must pay close attention to implementation, adhere to the concept of innovation and development, change the mode of development as the guide, with scientific and technological progress and advanced equipment as the support, adhere to the integration of industrialization and information; to accelerate the introduction and training of high-quality personnel as the core, improve the coal industry The overall level of employees; Adhere to local conditions, guidance for classification, overall promotion of large-scale coal mining ideas, improve the level of mechanization, automation and information; strengthen coal mine safety hazard investigation and prevention of gas, water and other major accidents, complete coal mine production conditions and Labor environment, improve safety and security capabilities, and achieve safe development.
Coal Industry: Promote the Construction of Large Coal Mines and Accelerate the Adjustment of Industrial Structure
The multi-faceted, small-scale, and extensive production is the crux of the constraints on the healthy development of China's coal industry. At present, China's coal industry is in the best period and critical period of “structural adjustmentâ€. The coal industry must firmly grasp the importance of large-scale modern coal mine construction, increase industrial concentration, resource utilization, and competitiveness of enterprises, increase the level of mechanization of coal mining, in order to accelerate the scale and modernization of coal production, and promote coal The optimization and upgrading of industrial structure will promote the stable, healthy and sustainable development of China's coal industry.
