Based on analysis of environmental geological conditions and disaster-forming mechanism karstic ground subsidence is considered as a result of common function of water cone forming caused by forced drainage, earth-cave forming induced by karstic mine mud-burst, devaluing of shear strength of cover layer caused by occasional heavy rainfall and so on.

Application and analyse of similar “Y” style ventilation mode in outburst mine;

1 Mine of Pingdingshan as a high gassy and high outburst mine,the paper researched on the mine field gas geological conditions and the geological factors affected to gas reservoir and gas outburst.

The coal roadway driving is a "bottleneck" problem of influencing and restricting the normal replacement of mining and driving in the outburst mines.

Finally,the system uses the artificial neural network technology which is introduced to arrange collection data,build predictive models,and forecast the probability of the mine water bursting in real time and effectively.

Distinguishing system study on resource of mine water inrush based on GIS;

Studies of water source determination method of mine water inrush based on Bayes' multi-group stepwise discriminant analysis theory

Identifying of mine water inrush sources by Fisher discriminant analysis method

This coal is an out-bursting of coal and gas mine.
