摘要:
考虑了新疆焦煤集团大倾角硬顶软底松软煤层的特殊性质和赋存环境复杂性,利用FlAC3D数值模拟软件对预裂弱化前后顶板应力变化特征和运移规律进行计算对比分析,结果表明,FlAc3D数值模拟软件能较好地应用于现场,数值模拟结果对采煤工作面安全开采具有一定的理论参考。
Abstract:
Considering the special nature and the occurrence of environmental complexity for the steeply dipping seam,hard roof,soft floor and soft coal in Xinjiang prime coking coal, the variation characteristic of stress and the rule of movement of the roof around the segment pre-blasting were calculated and comparatively analyzed by using FlAC3D program. The results indicate FlAC3D program can be used at in-site mining, and the results of numerical analysis can provide a certain reference for safe mining of the workface.
