摘要
根据相似理论探讨了相似材料模拟实验的观测方法与原理,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,运用Excel的函数计算出变形曲线,为研究缓倾斜煤层综采技术的应用和推广提供了理论依据,对指导该矿区减小采动损害及保护煤柱的留设具有实际应用价值。
According to the theory of similarity,the similar material simulation experiment was done and researched,and the paper studied the strata settlement and horizontal movement of postharvest slight slope working surface.The strata and the surface movement parameters have been obtained.Deformation curve was attained by use of Excel function evaluation.It provided us the theory basis for researching slight slope coal seam mining technology application and promotion.It also has practical application value for guiding the mine to reduce mining damage and set the protection pillar.
