摘要
提出采用注浆加固方式对顶板岩层进行控制,并详细对注浆加固方案及加固效果进行分析。结果表明,对破碎顶板岩层进行注浆加固后顶板强度、稳定性得以显著提升,采面回采过断层破碎带时未在出现顶板冒落问题,且煤壁片帮问题也得以改善,取得显著的应用成果。
The grouting reinforcement method is put forward to control the roof rock layer, and the grouting reinforcement scheme and reinforcement effect are analyzed in detail. The results show that the roof strength and stability can be improved significantly after grouting reinforcement of the broken roof strata, and the roof caving problem does not occur when the mining face passes through the fault fracture zone, and the coal wall side problem can be improved, and remarkable application results have been obtained.
