【摘要】 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。更多还原

【Abstract】 According to the practical observation data of ground sinking in many mining areas, a new ground sinking calculation formula is obtained. The relationship is expounded among the ground sinking value with the mean height of slope, the mean ratio of length to width of slope, the layout of protected ore pillar, the plane area of slope, the mean height from slope top to ground, the mean elastic modulus of covered rock stratum, the shape factor of slope, the mean angle of slope cutting rock stratum and distance from slope center.更多还原
