矿山地表沉降机理的初步分析与研究

Preliminary analysis and research on the mechanism of the mining area ground sinking

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 practical observation data of ground sinking in many mining areas, the author obtains a new ground sinking calculation formula. The relationship of the ground sinking value with the mean height of stope, the mean ratio of length to width of stope, the layout of protected ore pillar, the level area of stope, the mean height from stope top to ground, the mean elastic modulus of covered rock stratum, the shape factor of stope, the mean angle of stope cutting rock stratum and level distance from the stope centre have been expounded.
