摘要
结合王庄煤矿8101工作面的开采,采用数值模拟的手段,研究揭示了厚煤层、大采深、厚松散条件下一次采全高的地表沉陷规律,分析了一次采全高覆岩与地表的移动机理。研究成果对指导王庄煤矿一次采全高条件下留设保护煤柱和解放"三下"压煤具有重要的意义。
With the exploitation of Wangzhuang Coal Mine 8101 working face,used the method of numerical simulation,research reveals the thick coal seam,large mining depth,thick loose conditions once mining full high surface subsidence,analysis of the mobile mecha-nism of the once mining overall height of overlying strata and surface. Research on the conditions of mining a guidance of Wangzhuang Coal Mine protection coal pillar and the liberation of ＆quot;three＆quot; is of great significance for coal.
