摘要
充分考虑煤层顶板基岩风化破碎带条件,通过对井田内岩层的工程地质岩组进行划分,并依据RQD值、M值、Z值对安山煤矿主采5-2煤层的顶底板稳定性进行综合评价,提出煤炭开采工程中的工程地质问题。
Based on the analysis of weathered bedrock under seam roof, the engineering geological petrofabric of strata is divided. Ac-cording to the RQD, M and Z value, the stability of 5 -2 seam roof and floor in Anshan Coal Mine is evaluated. In the end, the engi-neering geological problems in coal mining are put forward.
