Aimed at the gas gush change law of every construction craft in the blasting driving face,the appropriate measure is adopted for gas comprehensive management.

It introduced the drift collocation of wetting dustproof system in driving face and the lectotype design of the correlation equipment.

This article introduces the situation of using the longhole shock blasting technology to prevent gas and coal outburst in driving face,analyzes the application result.

3422 driving face in Shitai Coal Mine.

A expert system for coal and gas outburst prediction of the working face based on Windows;

This paper discusses on some methods for treating the problem of the air leakage in the working face, such as arranging the tunnel rationally, closing corresponding tunnel, ventilating locally, constructing the ventilating facilities, etc.

The amount of gas emission prediction software of working face is developed based on VC++6.

Controlling measures of methane and coal dust and ventilation method in fully mechanized excavation face;

For gripping the distribution regularities of the dust, based on the theory of two-phase flow of gas and solid,and the characteristics of coal mine driving working face,using the discrete phase models of computational fluid mechanics to simulate the dust concentration during the ventilation process of coal roadway driving with forced ventilation.

Basing on the theory of two-phase flow of gas and solid, and the characteristics of coal mine driving working face, using the discrete phase models of computational fluid mechanics to simulate the dust concentration during the ventilation process of coal drift driving with exhaust ventilation.
