Possibility assessment of coal-gas outburst based on grey target model
Abstract：Based on grey system theory,multi-index weighted grey target model about hazard possibility division of outburst was established to quantify the hazard possibility of outburst.According to 10 measure stations data of coal-gas outburst area and off-target distance predict of coal seam hazard single index critical value,the hazard possibility of this mine area was evaluated,and the outburst hazard degree was divided.When using this model to evaluate the outburst hazard degree of Huabaogou Coal Mine which is identified non-outburst one,the result which is long off-target distance and low possibility to outburst,fits the reality.Thus,the model is available in practice to assess the possible of coal-gas outburst.
