摘　　要：为了对斜沟特厚煤层更好地进行开采,参考13号煤层实际地质条件及巷道布置方案,进行了相似材料模拟实验。研究的初始原型是与斜沟煤矿13号煤层相似的模拟初采工作面。利用模拟实验研究"错层位巷道布置无煤柱全高开采"采煤法的巷道布置、矿压显现以及巷道和围岩移动破坏的一般规律,进而论证斜沟煤矿应用此种采煤方法实现无煤柱回采的可行性以及采用此种方法的优点。To improve the mining technology of the extra-thick coal seam in Xiegou mine, based on the geological condition and roadway layout of No.13 coal seam, simulation experiment with similar materials was conducted. The initial prototype is the simulated initial mining face, which is similar to the No.13 coal seam. With the simulation on no-pillar full height cutting with stagger arrangement roadway layout, we could study the roadway layout, strata behavior, and movement and surrounding rock, which further demonstrates the feasibility of the method advantages damage rules of roadway and in no-pillar mining and its
