摘要
为了研究新疆中电投四棵树矿区2#斜井矿压问题,采用改进型空心包体应变计,对四棵树矿区2#斜井进行了3个测点的应力解除测量实验。根据实测数据,利用地应力计算程序,求解出每个测点的三维应力状态,再结合矿区地质构造,分析地应力与矿区地质构造的关系。通过研究,获得了四棵树矿区2#斜井的地应力分布规律及其与地质构造的关系,并初步分析了巷道矿压显现较明显的原因。
In order to study the problems of mine pressure in Sikeshu Mining Area,stress-relieving measurement test were made with improved hollow inclusion stress meter at 3 measurement points in Sikeshu Mining Area.Based on the measured results,three-dimensional stress state of each point was computed by stress calculation program,and the relationship between in-situ stress and geological structure was analyzed with the geological structure factors of the mining area.The laws of in-situ stress distribution and the relationships between in-situ stress and geologic structure in Sikeshu Mining Area were obtained.The reasons for the strata behaviors are primarily analyzed.
