摘要
运用岩土工程常用的FLAC3D软件,以昌恒煤矿9102工作面F1断层为研究对象,通过模型的建立和数值模拟分析,对昌恒煤矿9煤层开采进行应力、竖向位移与塑性变形分析,得出在不同开采进度条件下的覆岩变形破坏规律,获得了F1断层在采动影响后的裂隙演化特征,可为以后9煤层的安全开采提供理论指导.
The FLAC3 D software commonly used in geotechnical engineering was used to study the F1 fault of 9102 working face in Changheng Coal Mine. Through the establishment of the model and numerical simulation analysis,the stress,vertical displacement and plasticity of the 9 th coal seam mining in Changheng Coal Mine were analyzed. The analysis of the rules under different mining schedules and the analysis of the impact of F1 faults after mining can provide theoretical guidance for the future mining of the 9 th coal seam.
