On regional prediction of outburst danger at home and abroad on the basis of studying the theory and technology of the forecasting system, based on the Bai Shan ping mine deep level (400 ~ 600 m), roof and floor of coal seam occurrence condition, geological structure, etc., to the deep level development before and after the development for the time segment, a variety of existing regional prediction technology and method were applied, to decide the new mining area and forecasting outburst danger area of working face, to provide scientific and accurate prediction result, to provide the key basis for the scientific and reasonable using outburst prevention technology. On the level of extending the deep in the mine 3162 working face in the investigation of effects of excavating in coal roadway, it found that after the regional comprehensive prediction analysis, only to predict outburst danger area of local outburst prevention after unloading, the drilling cuttings index method is carried out on the whole face effect test, the drilling cuttings gas desorption index Δ h2 and the maximum drilling cuttings Smax of every hole is smaller than the reference in the outburst prevention provisions on the critical value, ideal pressure relief effect is obtained.
