煤岩力学参数测试及围岩稳定性评价

Testing of Mechanical Parameters of Coal Rock and Evaluation of Surrounding Rock Stability

针对同煤集团白洞煤业公司石炭纪煤层的赋存条件,在井下布置了合理的取芯钻孔,依据国家煤岩物理力学参数的测试标准,加工标准试件进行测试,得到了煤层顶底板岩石的物理力学参数,并对围岩的稳定性进行了评价。

In this paper,in view of carboniferous coal occurrence conditions of Baidong Coal company,reasonable core drilling is set up,and on the basis of test standards of our national physical and mechanical parameters,processing standard specimen is tested,in which the physical and mechanical parameters of coal seam roof and floor rocks is obtained,and the stability of surrounding rock is evaluated.
