深部煤炭开采逐步成为矿井今后的发展方向。为了探清唐口煤矿深部采动影响下覆岩形变演化规律,基于230、430采区煤层的实际赋存条件和开采方法,采用三维相似材料物理模拟试验对条带开采下覆岩运动进行了研究,获得了一系列有价值的监测数据,得出了深部开采条件下的覆岩形变演化规律。
Deep coal mining has gradually become the future development direction of the mine. In order to explore the evolution law of overlying strata deformation under the influence of deep mining in Tangkou Coal Mine, based on the actual occurrence conditions and mining methods of coal seams in 230 and 430 mining areas, the three-dimensional similar material physical simulation test was used to test overlying strata movement under strip mining A series of valuable monitoring data have been obtained and the evolution law of strata deformation under deep mining conditions has been obtained.
