【摘要】 本文介绍了一种新的开采沉陷预计方法—考虑煤岩物理力学特性与地层构造特性的岩石力学数值计算方法。在煤岩物理力学参数实验的基础上,本文应用FLAC^2D3.3和FLAC^3D1.0对河南省鹤壁矿务局4矿开采沉陷进行了预计,通过对比分析经典预计方法（概率积分法）与岩石力学数值模拟预计方法的结果,发现基于岩石力学的数值模拟方法能真实地模拟现场地质条件,补充一般经典方法不能考虑断层影响的不足,是一种简单易行的开采沉陷预计方法。更多还原

【Abstract】 A new method for prediction of the ground surface displacements due to coal extraction,which can take the physical & mechanical behavior of rock and coal and geological structure into account,is proposed in this paper.Based on the experiments of mechanical and physical behavior of rocks and coal,FLAC ^2D3.3 and FLAC ^3D1.0 are used to predict surface mining displacement of thick coal seam of No.4 Coal Mine of Hebi Coal Mining Bureau,Henan Province.By comparing the results of classical method with the results of the numerical simulation,it is shown that to predict surface displacement by using numerical simulation based on rock mechanics,which can simulate the actual geological conditions and improve insufficiency of the classical method,is a simple and effective way.更多还原
