通过数值模拟,分析了不同倾角煤层开采对覆岩破坏及导水裂隙带发育规律的影响。根据位移等值线图分析得出,随着煤层倾角逐渐增大其沉降位移有增大趋势;根据应力图分析可知,导水裂隙带的厚度随着煤层倾角的增大,也呈现一定程度的增加趋势。该结论为工程实践和采矿安全提供了理论依据。
Through numerical simulation, the influence of coal mining with different dip angles on the destruction of overlying strata and the development of water-conducted fracture zone was analyzed. According to displacement contour map analysis, it shows that the settlement displacement increases with the increase of coal seam inclination angle. According to the stress diagram analysis, the thickness of water-conducting fracture zone increases with the dip of coal seam, Increase the trend. This conclusion provides a theoretical basis for engineering practice and mining safety.
