摘要
运用数值模拟方法,主要分析了关键层的破断、关键层相对位置及采深等对围岩支承压力的影响;同时,研究了采空区支承压力的分布规律。研究结果对采场围岩的控制提供了一定的理论依据。
Based on the key strata theory, the effect of the key strata breakage, position and the effect of the cut depth on the surrounding rock abutment pressure is analyzed in numerical simulation ways. At the same time, the distribution law of the abutment pressure in the goaf is analyzed, and the cracked rock in the goaf can be divided into three areas: natural accumulation area, structure supporting area and compaction steady area. The conclusion provides the academic basis for the control of the surrounding rock.
