公路下压煤充填开采技术实践

Technology Practice of Backfill Mining Under Highway

近年来,我国煤炭资源开采强度不断加大,公路压煤资源量越来越多,如何确保在公路正常运行情况下,采出压煤资源成为一个亟待解决的问题。地下开采对公路的影响主要分为垂直移动变形和水平移动变形,结合公格营子煤矿充填开采公路下压煤的实例,经过相关数据的分析和对比,表明采用充填开采对矿区公路影响轻微,能达到采煤、安全和绿色的目的。

In recent years,the mining rate of coal resources enlarges in our country,and the coal resources under highway are becoming more increasingly.The problem that coal resources can be extracted becomes urgent under the condition that highway can run normally,which need be solved.The influence of coal mining under highway mainly includes vertical and level deformation.Combined with the example of coal mining under highway,through the analysis and contrast with related data about the Gonggeyingzi Coal Mine,mining with backfill can achieve the goal of mining coal,the safety and the green mining.
