摘要
对目前煤矿掘进工作面煤与瓦斯突出预测指标进行分析对比,选取钻屑瓦斯解析指标和钻屑量指标对煤矿井下掘进工作面进行煤与瓦斯突出危险性跟踪考察,对不同瓦斯预测指标对煤层未来一段时间瓦斯动态变化间的灰色相关关系进行定量研究,找出能有效反映瓦斯变化的指标,帮助煤矿企业进行正确决策。
Currently coal mine heading face coal and gas outburst prediction index were compared, the selection of drill cuttings gas desorption index and drilling bits index of coal mine heading face of the danger of coal and gas outburst tracking investigation and for different methane prediction index of coal seam in the future for a period of time of gas dynamic changes between the grey correlation of quantitative research, find can effectively reflect the gas change index, help coal mining enterprises to carry out correct decision.
