Research On The Prediction Of Coal And Gas Outburst And Emergency Response Mechanism

Based on the statistic analysis of coal and gas outbursts of Pingdingshan Mine area, the general law of coal and gas outbursts was summarized; study the coal seam gas distribution law, then analyzed the gas outflow law and its influencing factors, the stepwise regression method was established, and it was applied at No.10 Mine of Pingdingshan Tian'an Coal Mining Corp. Ltd.; the causes and distribution of deformed coal, its structure and gas parameters characteristics was analyzed, the relationship between deformed coal and outbursts was reduced, and deformed coal indicator was applied to the outbursts prediction; The characteristics of the geological structure of the study area, its causes and distribution were studied, its control on the distribution of coal and gas outburst was studied, the relationship between geological structure and outbursts was conducted; clustering extension model for coal and gas outburst prediction was established, regional forecast was done at selected area by indicator methods, clustering extension method and gas geological methods; coal and gas outburst emergency plan was studied for coal and gas outburst accident characteristics, the mechanism of outburst emergency response was brought forward, and a coal and gas outburst emergency decision support system was established, which provided guidance for coal and gas outburst emergency rescue of Pingyu"8·1"outburst.
