煤炭是我国的主体能源,煤炭产业是支撑国家经济发展的支柱之一.随着浅层煤矿接近枯竭,深部煤矿(500~1 000 m)开采已成必然.2013年我国煤炭产量达37亿吨,其中开采深度大于500 m的矿井超过40%,主体开采深度已达800 m以下,已有40多个矿井的开采深度超过千米.深部煤层的瓦斯爆炸及岩层垮塌、突水等地质灾害发生率高、偶然性强,严重威胁采掘矿工生命安全.国家安全监管局统计结果表
Coal is the main energy of our country and the coal industry is one of the pillars supporting the country’s economic development.With the shallow coal mines drying up, it is inevitable to mine deep coal mines (500-1000 m) .In 2013, China’s coal production reached 3.7 billion tons , Of which more than 40% are mined at a mining depth of more than 500 m and the main mining depth has reached 800 m, and more than 40 mines have been drilled more than 1 km in depth. Gas explosions in deep coal seams and geological disasters such as rockfall collapse and water inrush occur High rate, strong contingency, serious threat to mining life safety of miners.
