|
|
|
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.
