在现场观测的基础上,运用FLAC3D数值模拟软件,依据钻孔柱状图和采掘应力影响范围建立相应的几何模型,通过对济二煤矿93上01工作面开采后煤体与采空区下方应力分布情况的数值模拟,并对模拟结果进行理论分析,较准确的掌握了回采工作面的应力分布规律,为冲击地压显现防治提供理论支持,以便制定相应的防冲措施。
On the basis of field observation, the corresponding geometric model was established by using FLAC3D numerical simulation software according to the histogram of borehole and the influence range of mining stress. Through the analysis of the stress distribution below the coal and the goaf The numerical simulation of the situation, and the theoretical analysis of the simulation results, a more accurate grasp of the stress distribution of mining face, provide theoretical support for the occurrence of rock burst prevention in order to formulate the corresponding anti-shock measures.
