沿空掘巷将巷道布置在应力降低区,有利于巷道维护。应用FLAC模拟掘进后的巷道所处应力状态,并利用充填体置换煤柱,依据模拟结果提出巷道支护设计方案,并通过实践来论证支护设计的实用性。
Roadway along the roadway will be arranged in the stress reduction zone, is conducive to roadway maintenance. FLAC is used to simulate the stress state of the roadway after tunneling, and the filling pillar is used to replace the coal pillar. Based on the simulation results, the design scheme of roadway support is proposed and the practicability of the support design is demonstrated through practice.
