Study on Accident Gestation and Immunity Evolution of Underground Goaf Energy System

摘要：

The form of goaf, distortion and destruction of wall rock is very complex when the underground mineral resources are exploited cosmically in a long period. According to statistic analysis of mine accident in every country, the goaf roof-fall accident accounts for 20～30 percent of all mine accidents. The destruction and movement of wall rock are more notable in the function of adverse factor such as Long Time Tiny Breach Effect and underground Water Induced Stress Corrosion. The main representations are (1) Wall rock of goaf occurs explosive destruction; (2) Wall rock of goaf occurs disjunction and caving while produces pressure wave when it reached a certain span, which produces the instantaneous destruction in the limit stress state; (3) Rock mass occurs non-steady concussion fracture by the action of structural stress. According to the particularity, complexity, levity of mine energy system and a great diversity of accident, mine energy system accident-gestation (roof-fall accident) and the evolved process of immune function are studied through Time-Dependent, Space-Dependent and Energy-Dependent in this article, in order to explore an approach to guard against underground goaf roof-fall accident.
