Prevention and Control Technology of Coal and Gas Outburst Based on Fault Simulation and Prediction .

In order to further verify the fault conditions of the no exploration zone within the mining area of the minefield and to reduce the fault affected to the gas outburst, the Geostructure software was applied to simulate and predict the fault to reduce the risk of the mine gas outburst.According to the software applied to the fau It simulation and prediction results of North Goonyella Mine in Australia and Yuzitian Mine Shaft of Hunan Yumin Mine in China, in comparison between the actual expos ed conditions of the faults during the mining process in the mines, the fault numbers, the fault existing probability and the gas outburst risk was applied to verifty the fea sibility of the Geostructure software applied to simulate and predict the faults within the mining area of the minefield and to prevent the gas outburst, which could provid e the references to highly reduce the gas outburst risk during the mining process.
