摘要
以淮南潘集煤矿外围(深部)勘查区工程地质钻孔26-3孔为研究对象,通过统计分析含煤段地层的岩性厚度、RQD和抗压强度三方面特征,评价了钻孔煤系地层工程地质特征,并在此基础上划分了工程地质岩组;结果表明该钻孔工程地质条件较差,煤层顶底板多为泥岩,力学强度低,稳定性差。
Using engineering geological drilling hole 26--3 in Huainan Panji mine peripheral deep exploration district as the research object, through statistical analysis of the three characteristics of coal strata rock thickness, RQD and compressive strength characteristics, the paper evaluates the drilling coal engineering geological characteristics of the strata, and divides the engineering geological rock group on this bases. The results show that the engineering geological condition of drilling hole is poor. The roof and floor of the coal seam are mudstone, which has low mechanical strength and the poor stability.
