摘要
以淮南某煤矿1811(1)工作面为研究对象,利用相似材料模拟试验,分析受采动影响的上覆岩层的移动变形规律。结果表明,受采动影响的上覆岩层依次发育成冒落带、裂隙带、弯曲带。通过对下沉、倾斜、曲率、水平移动、水平变形五个参数的动态曲线分析,总结上覆岩层的力学状态。
A certain mining face 1811（1） of Huainan was study.Similar materials were used in simulation experiment .The move-ment and deformation of overburden strata were analyzed under the mining influence .The result showed that after mining , in the over-burden strata, collapsing strap, crack strap and deflection strap were formed in turn .According to the five parameters of subsidence , inclination, curvature, horizontal movement and horizontal deformation , the mechanical state of overburden strata were summarized .
