摘 要:为了解掌握矿井采矿工程设计所需的基础地质资料,提出合理的巷道支护方式及参数,对试验矿井进行地质力学测试。进行了三处测站的地质力学测试,选用钻孔电视设备对围岩结构进行观测,井下的原位测量选取围岩强度测定装置,采用水压致裂地应力测量装置测量地应力。通过分析试验矿井巷道围岩所处原岩应力分布特征、围岩强度及节理裂隙发育程度,为巷道安全快速掘进与支护工艺及参数的选取提供了可靠依据。In order to grasp the basic geological data needed for mine mining engineering design, a reasonable roadway support mode and parameters are put forward, and the geomechanics test of the test mine is carried out.The geomechanics tests of three stations are carried out, the borehole television equipment is selected to observe the surrounding rock structure, the underground in-situ measurement selects the surrounding rock strength measuring device, and the hydraulic fracturing in-situ stress measuring device is used to measure the in-situ stress. Through the analysis of the stress distribution characteristics of the original rock, the strength of the surrounding rock and the development degree of joints and cracks in the surrounding rock of the tested mine roadway, it provides a reliable basis for the safe and rapid excavation and support technology and parameter selection of the roadway.
