摘要: 随着煤矿采深的不断加大,深部软岩交岔点稳定性控制已成为煤矿开采的又一难题。为了良好地控制交叉点处围岩的稳定性问题,结合鹤壁五矿三水平二车场交岔点处支护工程实例,通过地质调查、理论分析及数值模拟(FLAC3D),提出了鹤壁五矿三水平二车场交岔点处围岩稳定性控制对策——锚网喷+锚索+单桁架耦合支护技术,并在实践中得到了验证,效果良好。

Abstract: As the coal mining grows deeper and deeper, the control of the stability of the rock mass at the intersection points in great depth has become a difficult issue. Countermeasures to control the stability of the rock mass at the intersection point of the second parking area on the third level of Hebi No. 5 coal mine, i.e., the coupling support including rock bolting, wiremeshing, shotcreting, plus anchor cables and single truss, are proposed on basis of geological investigations, theoretical analysis and FLAC3D numerical simulations. The countermeasures have been applied and proved to be effective. 

Key words: soft rock, intersection, coupling support
