In recent years, the profitability of the coal industry has improved and the quality of economic operations has continued to improve. The industry has made new breakthroughs in vigorously developing coal washing and processing, and strengthening the clean production and utilization of coal. According to data provided by the China Coal Industry Association, the total amount of raw coal washed into the country increased from 370 million tons in 2000 to 850 million tons in 2006, and the washing rate increased from 25.9 in 2000 to 35.7 in 2006. The comprehensive utilization rate of wastes such as coal gangue and coal slime increased from 42 in 2000 to 53 in 2005. By the end of 2006, more than 300 coal gangue, coal slime, gas, and blast furnace gas power plants have been built nationwide, with a total installed capacity of 12 million kilowatts and nearly 90 million tons of low calorific value fuel. In 2006, the national coal mine gas extraction reached 3.2 billion cubic meters, an increase of 2.6 billion cubic meters compared with 2000.
While making great progress, the coal industry still has problems such as low coal mine resource recovery rate, low raw coal washing rate, and backward technical equipment. The enterprises participating in the meeting said that they will speed up the development of recycling economy, increase input to promote energy-saving emission reduction technology transformation, development and application of comprehensive utilization of coal resources and clean coal technology, and further improve the efficiency of coal resource utilization.
