中文摘要：

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。

英文摘要：

Through the numerical simulation in this paper,the influences of mining coal sea ms with different dip angles on the overburden failure and the development law of water-flow fractured zone was analyzed. The analysis on the displacement conto ur lines showed that with the seam dip angle increasing,the subsidence displacem ent was increasing gradually.The analysis on the stress diagrams showed with the increase in dip angle of coal seam,the thickness of the water-flow fractured zo ne also increased in a certain degree.These conclusions provided a theoretic bas is for engineering practice and safety of mining.
