高瓦斯矿区复杂地质条件安全高效开采关键技术

Key technique to high efficiency and safe mining in highly gassy mining area with complex geologic condition

为解决高瓦斯矿区复杂地质条件安全高效开采技术难题,根据淮南矿区实际,通过理论研究和工程实践,提出并研究了煤与瓦斯共采技术、极易离层煤岩支护工程技术、复杂地质条件下采矿工程地质保障技术、以及绿色开采等高瓦斯矿区复杂地质条件安全高效开采关键技术,确定了关键技术参数,全面考察了现场应用效果.

In order to solve technical problems exist in the course of high efficiency and safe mining of Huainan mining area, through theoretical study and engineering practice, the key technique to high efficiency and safe mining in highly gassy mining area with complex geologic condition was put forward and studied, including the coal and gas simultaneous extraction technique, and the timbering engineering and technique to coal and rock seam with the character that the layer is mighty easy part from each other, and the geology guarantee technique in mining engineering, and the green mining technique. Key parameters of the technique were found and the application effect was fully reviewed.
