    Anhui coal mine safety costs the highest

    From the 2010 China international symposium on mine gas prevention and control technology news briefing learned that four mining group in 2009 extraction of up to 50 yuan per ton of coal safety cost, the gas control special funds for not less than 15 yuan, is the highest. It is understood that the China coal mine gas control technology international symposium 2010 is the largest, the highest standard and the most technical academic seminar of international mining industry. At that time, there will be more than 10 world coal mining countries, such as Australia, Germany, Japan, Poland, Britain, Russia, etc., which will participate in the meeting. At present, 98% of the coal resources in anhui province are concentrated in the two huai mining areas, according to zhang hage, deputy director of anhui economic and information commission and director of the coal office. Due to the effect of multiphase geological effect in huainan coal mining area and the burial depth, complex geological structure and coal seam coal YanSong soft, low permeability, high gas content of coal seam, the gas pressure, coal seam spontaneous combustion period is short, the coal dust explosion risk is big, is one of the most complicated mining conditions of mining area in our country. According to statistics, more than 90% of coal production in anhui province comes from high gas and coal and gas outburst mines, of which 70% is produced by coal and gas outburst mines. Coal mine gas seriously restricts the safe development of anhui coal mine, which is one of the important bottlenecks affecting the production capacity of coal mine. In the 14 years from 1990 to 2003, there were 135 accidents in coal mines in anhui province, killing 688 people. Especially in 1997, huainan mining group three mines and pan Xie Erkuang ensued, 88, 45 deaths of gas explosion, 2003 86 people died in luling coal mine of huaibei mining industry group, the gas explosion accident, losses.
