基于灰色理论确定煤与瓦斯突出预测敏感指标

Determining Sensitive Indexes of Coal and Gas Outburst Forecasting Based on Grey Theory

为了提高煤矿瓦斯突出危险性风险评价的准确度和可靠性,利用灰色系统理论中灰色关联分析数学模型,定量分析了4种预测煤与瓦斯突出的指标,并确定了能够较精确反映龙山煤矿二1煤层煤与瓦斯突出预测的敏感指标,该结果为龙山矿煤与瓦斯突出预测指标的选择提供了定量化依据.

In order to improve the accuracy and reliability of risk assessment of coal mine gas outburst hazard, this paper used math- ematic model of grey association analysis to quantitatively analyze the four indexes to forecast coal and gas outburst and deter- mine some sensitive indexes which could reflect coal and gas outburst forecast more accurately in the III coal seam of Longshan mine, and provided a quantitative basis for forecasting index choice of coal and gas outburst.
