大采深半煤岩开拓巷道注浆修复技术的应用

Application of Grouting Repair Technology in Development Roadway with Large Mining Depth Semi-coal and Rock

王楼煤矿的七采胶带山下的围岩性能较差,且整体强度较低,如果巷道内部存在较大应力的话,则会在其内部表现出较大的矿压,进而在之后使得巷道严重变形,最终才会对矿井生产产生较差的影响.而只有合理采用煤岩开拓巷道注浆修复技术才能够有效地解决巷道变形的问题.

The surrounding rock of No.7 mining belt in Wdnglou Coal Mine has poor performance and low overall strength.If there is a greater stress inside the roadway,it will show a greater pressure inside the roadway,then make the roadway deformed seriously,which will eventually make a worse impact on mine production.Only by reasonably using grouting repair technology of coal and rock development roadway can effectively solve the problem of roadway deformation.
