采用智能松动圈测试仪和矿用钻孔窥视仪对巷道围岩的损伤与变形状况进行了测试分析。测试结果表明,测试巷道围岩的松动圈深度约为2.6 m,这为确定合理的锚杆支护参数提供了重要依据。
The testing and analysis of the damage and deformation of roadway surrounding rock are carried out by the intelligent loose ring tester and mining drill peephole. The test results show that the depth of the loose ring around the test tunnel is about 2.6 m, which provides an important basis for determining the reasonable bolting parameters.
