The disaster of mine water burst is one of the five mine disasters, mine behind the water has an expansive future and the forecast of mine roof water inrush becomes an extremely important content in the mine water inrush prevention and cure, along with the increase of energy sources requirement by country economy.

Mathematic models for mine fire simulation and determination of refuge route;

Selection of temperature sensors in testing system of mine freezing temperature field;

Reconstruction design on mine auxiliary transportation system in Wangpo Mine;

Artificial neural network is non-linear,error-tolerant,self studying and on-line,so that is suitable to safety evaluating of shaft ventilation system.

Through analyzing the problems in coal production,a shaft operation control system has been developed and a set of rule has been edited,which has achieved good economic and social benefit.
