The occurrence of minc accidents such as fire and gas explosion always causes great loss of estate. So it is very important to quickly conrol the accident situation and correctly make rescue. GIS-based mine safety decision support system (abbreviated for “MGIS system”) can find the best escaping route and rescue route through shortest route analysis and loop analysis, also determine the fire influence area and fire source through connectivity analysis and ancestor tracing analysis. And it can determine all exits and blast holes to be closed so as to implement closing quickly when the fire is hard to be controlled.

摘要

Micro cracking in solid material is a phenomenon of solid plane bifurcation with incompatible micro-rotation. Therefore it is important to analysis the micro-rotation field in a strained material in fractute mechanics. On the basis of strain-rotation (S-R) decomposition theorem, the geometric criterion of cracking has been established. In order to verify its validity, using grating experimental method the thin compact tension specimens were investigated. The analysis results show a good agreement between the experimental and geometric criterion.
