THE STUDY OF WATER INRUSH AND MUD BURST DISASTER AND ITS PREVENTION AND CONTROL

Water inrush and mud burst disasters seriously threatens the safety of tunnel construction. Find out disaster causes, is the foundation of the tunnel construction disasters prevention and control measures of decision. Three causes of water inrush and mud burst disasters were advanced according to the analysis of the lose effectiveness of water-resisting or mud-resisting rock-soil plate, and water inrush and mud burst disaster-causingstructure and its size, based on the description of the definition of water inrush and mud burst, and the comprehensive prevention and control system, includingguaranteeof water-resisting or mud-resisting rock-soil plate thickness, treatment of jointed and cracked water-resisting or mud-resisting rock-soil plate and water inrush disaster-causingstructure, consolidation and supporting of mud burst disaster-causing structure was also advanced in this paper.
