辛置煤矿310轨道巷围岩破裂范围研究

Study on surrounding rock rupture range of Xinzhi Coal Mine 310 track roadway

辛置煤矿310轨道巷属于高应力软岩巷道,地质构造和岩层结构非常复杂多变。为了解该巷道的松动范围、塑性区分布和围岩破坏情况,采用U510非金属超声波检测仪,在辛置煤矿310轨道巷左右两帮合理布置检测点,进行现场松动圈测试。获得一系列测试结果,运用测试结果及围岩松动圈支护理论,可对310轨道巷支护提供理论依据。

Xinzhi coal mine 310 rail lane is belongs to high stress soft rock roadway and with very complicated geological structure and rock structure. To understand the plastic zone distribution and scope of loose surrounding rock of roadway damage. Adopt the U510 nonmetal ultrasonic detector in coal mine of rational distribution of two testing point around 310 rail lane to test the loose circle to obtain a series of test results. Using the test results and the surrounding rock loose circle supporting theory,can be to optimization of 310 rail roadway supporting technology.
