摘　　要：为研究注浆改造前后对五沟煤矿1010工作面开采的影响,利用Flac3^D数值模拟,选取合适的注浆孔间距,在此基础上通过对比分析研究围岩应力变化和移动破坏规律。结论表明:注浆孔间距的布置宜45m至50m为宜,发现注浆改造后煤层的应力及位移变化比改造前有所减小。因此,进行注浆改造数值模拟对煤层的安全开采提供了有效的评估依据。As the research before and after grouting reconstruction of Wugou Coal Mine 1010 working face mining,the influence of using Flac3^D numerical simulation,selecting suitable grouting hole spacing,on this basis,through comparing analysis of surrounding rock stress change and destruction rule of mobile.Conclusion show that the grouting hole spacing arrangement should be 45 m to 50 meters advisable,found that after grouting reconstruction of coal seam of stress and displacement change less than before.As a result,the numerical simulation of grouting reconstruction to evaluate the safety of the coal seam mining provides effective basis.
