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。
Based on the principle of determining the critical value of coal and gas outburst prediction index, the influencing factors and variation rules of coal and gas outburst electromagnetic radiation forecasting in working face were investigated on site, and the comprehensive evaluation method of predicting the critical value of coal and gas outburst electromagnetic radiation in working face was put forward. And conducted a pilot application at Hongling Coal Mine in Shenyang Mining Group. The application results show that the comprehensive evaluation method of the critical value of coal and gas outbreak electromagnetic radiation predicting index is simple and convenient, accurate and reliable, and provides a new idea and new method for the electromagnetic radiation method to predict the critical value of coal and gas outburst method.
