缓倾斜煤层相似材料模拟试验研究

Research on similar material simulation experiment for gently inclined coal seam

以安徽省淮北市海孜矿为原型,根据相似理论,对采后缓倾斜工作面上覆岩层下沉和水平移动进行了相似材料模拟试验的研究,获得了岩层与地表移动参数,为缓倾斜煤层综采技术的应用和推广提供了理论依据,对指导海孜矿区减小采动损害及保护煤柱的留设具有实际应用价值。

The paper took Haizi coal mine of Huaibei city for prototype.According to the theory of similarity,the similar material simulation experiment was used to research the strata sinking and horizontal movement of gently inclined working face in the post-harvest.The strata and the surface movement parameters have been obtained.The study can provide the theory basis for the promotion and application of gently inclined seam mining technology.It also has practical value for guiding the Haizi coal mine to reduce mining damage and set the protection pillar.
