| 摘 要： | 现有锚杆支护参数确定多依据工程类比法,支护方案的确立缺少科学理论依据。因此,通过分析围岩松动圈原理,并应用超声波探测金川Ⅲ矿1554和1220m水平运输巷道的围岩松动范围。依据围岩松动圈测试结果,确定支护参数和支护方案,并通过数值模拟进行支护效果分析。研究结果表明,超声波能够探测围岩松动范围;围岩松动圈理论指导锚杆支护参数的确定是合理可靠的。

| Abstract: | The existing design parameters of bolt support are determined according to engineering analogy method,and the establishment of supporting scheme is short of theoretical foundationTherefore,with analysis of the surrounding rock loose circle theory and the application of ultrasonic detection technology,the wall rock looseness ranges of 1 554 and 1 220 horizontal haulage tunnels in Jin Chuan Ⅲ mine are detectedIn the light of the test results of surrounding rock loose circle,support parameter and scheme are determinedAnd supporting effect is studied by numerical simulationThe results showed that the ultrasonic can detect the range of wall rock loosenessIt is reasonable that surrounding rock loose circle theory guides the determination of parameters of bolt support |
