Abstract:Based on the engineering character of rock stratum and the essential character of mining subsidence,the reality and feasibility for founding the non-linear subsidence are discussed.The results from investigation,experimentation and observation in aspects of non-linear subsidence are summarized.They are: non-linear chacter of damaged rock mass induced by mining,the damaged effect of mining subsidence,the fractal fracture network of rock mass induced by mining,its regularity of evolution,self-organizational process of mining subsidence,the problems of fracture boundary and fissuring of rock mass induced by mining,mechanism of catastrophe of overburden′s subsidence,the effect of fractal interface on fault activation and the "S" shaped increase rule of surface subsidence. A forecasting model its countermeasures according to the mechanism and regularity of non-linear mining subsidence are suggested and its theoretical concept is put forward.
Keywords:Non-linearity Mining subsidence Fractal Synergetic Self-organization Catastrophe Chaos
