以评估煤与瓦斯突出的危险程度为目的,以突出宏观显现对煤与瓦斯突出危险数据库进行分类,以三维立体图展现突出危险与瓦斯压力、放散初速度、坚固性系数和破坏类型。建立了突出危险灰色关联度模型,结果表明:煤体破坏类型与坚固性系数是作用煤与瓦斯突出的关键指标,主要导致在巷道或采面发生的突出;瓦斯压力与放散初速度是影响煤与瓦斯突出的控制指标,钻孔突出多数由瓦斯参数主导突出过程。 In order to evaluate the dangerous degree of coal and gas outburst, the database of hazards of coal and gas outburst is classified to highlight the macroscopic manifestation. The three-dimensional perspective diagrams are used to show the prominent danger and gas pressure, initial velocity, solidity coefficient and type of failure. The model of highlighting the degree of gray incidence is established. The results show that the type of coal failure and the coefficient of robustness are the key indicators of the effect of coal and gas outburst, which leads to prominent in the roadway or mining face. The gas pressure and initial velocity Outburst control indicators with gas, most of the borehole prominence process highlighted by gas parameters.
