摘要: 基于FLAC3D数值模拟软件与Midas/GTS辅助建模技术,采用Mohr Coulomb本构模型,对西马煤矿南一采区工业广场保护煤柱范围内的1327工作面进行了似膏体充填开采后的地表移动变形预计分析,并将其结果与概率积分法预计结果进行比较,得出FLAC3D模拟结果(该结果符合实测数据)。分析结果表明:FLAC3D数值模拟不需要确定繁杂的参数,而是以实际钻取的煤岩的物理参数为计算依据,较概率积分法更为简捷;研究成果为似膏体充填开采沉陷预计分析探求了一种更为高效的研究方法,也是对于传统概率积分预计方法的有效补充。

Abstract: Mohr Coulomb constitutive model is used to predict and analyze the ground movement and deformation of 1327 working face after paste-filling mining of the industrial square coal pillar in Xi-ma Coal southⅠmining area based on FLAC3D numerical simulation software and modeling technology of Midas/GTS.After comparison with the probability integration method,it is found out that FLAC3D simulation results match with the measured data.Analysis results indicate that,FLAC3D numerical simulation do not need complex parameters but adopt the actual physical parameters of coal and rock,so it is simpler.The research result displays a more efficient research method for predicting and analyzing the paste-like filling subsidence and is considered as an effective complement to the traditional probability integration method.
