摘　　要：采用ANSYS数值模拟分析钻孔周围煤体以及围岩的应力、应变和位移分布规律,并对固化前后的应力、应变和位移参量进行分析,得出固化前后煤岩的稳定规律。通过适当选择抽采钻孔固化浆料的参数,并对抽采钻孔注浆单元取样,以此来检验固化煤体后的抽采钻孔稳定效果,在现场进行了尝试应用。The ANSYS numerical simulation was applied to analyze the surrounding coal mass of the borehole as well as the stress, strain and displacement distribution law of the surrounding rocks. The paper analyzed the stress, strain and displacement parameters before and after the consolidation and the coal and rock stability laws were obtained before and after the consolidation. With the suitable selection of the parameters of the consolidated grouting material for the gas drainage boreholes, the sampling was made from the grouting section of the gas drainage borehole in order to inspect the stability effect of the gas drainage borehole after the coal consolidated. A trial application was conducted at the site.
