煤与瓦斯突出电磁辐射预测指标临界值的确定

DETERMINING CRITICAL VALUE OF ELECTROMAGNETIC EMISSION PREDICTION INDEX ON COAL AND GAS OUTBURST

基于煤与瓦斯突出预测指标临界值确定原则,现场考察了工作面煤与瓦斯突出电磁辐射预测影响因素及变化规律,提出了工作面煤与瓦斯突出电磁辐射预测指标临界值的综合评判确定法,并在沈阳矿业集团红菱煤矿进行了试验性应用。应用结果表明,工作面煤与瓦斯突出电磁辐射预测指标临界值的综合评判法,具有简单方便、准确可靠的特点,为电磁辐射法预测煤与瓦斯突出临界值的确定,提供了新思路和新方法。

On the basis of determining principle of critical value on coal and gas outburst forecasting index, influence factors and their changing laws of forecasting danger of coal and gas outburst by way of electromagnetic emission （EME） in working face were observed, a comprehensive judging method of critical value on coal and gas outburst forecasting index was put foreard and applied the method to Hongling coal mine of Shenyang mining group. The application results indicate the method has many characteristics, such as simple and convenient, accurate and reliable. Itsupplies a new thinking and method for determining critical value on coal and gas outburst EME forecasting index.
