摘要
针对采场围岩应力复杂多变和难以预测的实际问题,以FLAC3D模拟软件建立了三维空间力学模型,开展了采场上覆岩层应力的动态演化和分布规律数值模拟分析,得出了工作面不同推进距离采场上覆岩层在走向和倾向上应力的分布特征,可为采场合理支护方式、支护参数和矿山压力及其控制等有关问题提供数据支持和依据,保障采煤工作面安全有序进行。
Aiming at the actual problem that the stress distribution of stope wall rock is complicated and difficult to predict,a three-dimensional numerical calculation model is established by FLAC3D software.The dynamic evolution of the stope overburden stress and distribution are analyed,through the analysis of the simulation results,the different face advance distance of mining overburden on the trend and tendency of stress distribution characteristics are gained,which can provide reasonable data support and basis for stope support mode,supporting parameters and mining pressure,ensuring the safety of coal mining working face.
