根据多个矿区的实际地面沉陷观测资料,总结出了新的地表沉陷量估算公式,指出了地表沉陷量与采空区平均净高、采空区平均长宽比、留设矿柱布局、采空区平面积、采空区平均距地高度、覆岩平均弹性模量、采空区形状因子、平均切岩角、采心距间的关系。
According to the actual ground subsidence observation data of a number of mining areas, a new formula for estimating the amount of subsidence is summarized, and the relationship between the surface subsidence and the average net height of the goaf, the average aspect ratio of the goaf, The area of the empty area, the average height of the goaf, the average elastic modulus of the overburden, the shape factor of the goaf, the average cutting angle and the distance between the mining area and the mining area.
