| 摘 要： | 为了安全高效开采采空区上覆煤层,基于其层间岩层移动变形问题的重要性,采用相似模拟实验的方法研究了采空区上覆煤层开采层间岩层相同水平层位与竖直层位岩层的移动变形情况.结果表明,采空区上覆煤层开采使下部煤层开采的原"三带"均向上位扩展,并出现了层间岩层控制层;采空区上覆煤层开采层间岩层出现变形盆地,在控制层以下的岩层出现下沉盆地,而控制层以上的岩层出现分形盆地;同一层位岩层下沉随工作面推进呈现整体移动的偏态性,在移动变形过程中,控制层以上的岩层移动变形呈现连续性的特点,控制层以下的岩层移动变形呈现突变性的特点.

| Abstract: | To guarantee safety and high productivity of the left-over coal seam mining above gob area,and considering the importance of the movement and deformation of rock strata between coal seams,we use similar simulation experiment to study the movement and deformation rules of rock strata in the same horizontal layer and vertical measuring position in the mining process.The results show that original three zones of the lower coal seam develop upwards and a controlling stratum presents duo to the mining operation ... |
