高产高效矿井建设是通过改革采煤工艺，优化开拓布局，合理集中生产等手段来实现的。同时，还必须考虑如何减少巷道失修对高产高效矿并建设的影响。据调查，鹤壁矿务局大约有8（）d的回采巷道处在中等稳定或不稳定岩层中，这些巷道几乎都要经受采动压力影响，大部分巷道发生较 High-yield and high-efficiency mine construction is achieved through the reform of coal mining technology, optimization of layout, rational concentration of production and other means. At the same time, we must also consider how to reduce the impact of roadway disrepair on the construction of high-yield and high-efficiency mines. According to the survey, Hebi Mines Bureau about 8 () d of the mining roadway in the middle of stable or unstable rock formation, almost all of these roadways to withstand the impact of mining pressure, most of the roadway occurred
