Development of cracks constitutes the most direct reason for the change of water in the soil, besides which, rising height and developing level of the water flowing fractured zone in the upper rocks are also important.
就开采条件和土壤沉陷破坏相关性给出了解释,指出土壤的物理性状变化是由土壤几何变形引起的,水平变形和水平移动引起的土壤拉应力和压应力的变化,导致容重和孔隙度变化;裂缝的发育是导致土壤水份变化的最直接原因,上覆岩层的导水裂隙带的上升高度和发育程度也是土壤水份变化的重要原因。
