淮南矿区现代采矿关键技术

Key technology for modern mining in Huainan coal area

为实现高瓦斯矿井安全高效开采,根据淮南矿区的实际情况,研究了高瓦斯煤层群煤与瓦斯共采技术及通风方式、开采程序技术原则、安全高效采煤技术,探索实践了瓦斯综合利用、环境治理、矿井降温技术等绿色开采技术.确定了关键技术参数,全面考察了现场应用效果.根据研究结果,确立了现代采矿的基本内涵.

For the sake of safe and highly efficient mining in gas-rich mines, by taking the situations of Huainan collieries into consideration, analyzed coal and gas simultaneous extraction technology, corresponding ventilation methods, mining procedures and technological principles, and safe and highly efficient coal mining technology to be applied in gas-rich seam group mining practices. In addition, researches were also conducted on such green mining technology as concerned with comprehensive gas utilization, environment treatment and protection, and mine temperature reduction, and the results of the above-mentioned researches were applied in mining practices. Parameters for all the above-mentioned techniques were determined with comprehensive application results examined. In this way, the concept of modem mining was defined.
