The authors of this article have described essential conditions and environmental forms of collapse in covered karst mine areas in China as well as external causes such as drastic lowering of the ground water surface. The authors present a theory of suction action causing collapse, and an air-charging method to prevent the collapse. The result obtained by this method is favorable.
