Cavity instability in metal mine not only affect the safety in normal production of mine, but also makes the recovery of mineral resources inconvenient. Thus, to analyze the cavity instability and to grasp the instability modes of cavity and related information accurately provide a foundational base to formulate particular schemes. It is of great practical importance to analyze cavity instability.
In view of the specific engineering conditions of cavity instability in Dongguashan Copper Mine, this paper...
