电磁辐射技术在鹤岗南山煤矿突出预测中的应用

采用电磁辐射监测技术,结合常规预测法,在鹤岗南山矿进行煤与瓦斯突出危险性预测。实践表明,电磁辐射信息综合反映了南山矿煤与瓦斯突出危险的主要影响因素和危险程度。通过南山矿突出危险工作面电磁辐射指标与常规指标的对比表明,电磁辐射指标与钻屑瓦斯解吸指标Δh2和钻屑量S这两个常规指标有着较好的一致性,而与钻孔瓦斯涌出初速度q的一致性较差。因此可以采用S,Δh2指标与电磁辐射指标相结合的方式对南山矿煤与瓦斯突出危险进行综合预测。

Application of Electromagnetic radiation technique in outburst Prediction in Hegang Nanshan Mine

Based on the complex analysis of various coal and gas outburst prediction techniques and prevention measures used in our coal mines, the hazard prediction of coal and gas outburst was conducted in in Hegang Nanshan Mine with electromagnetic radiation monitoring technique and conventional method. The prediction results shown that the electromagnetic radiation information can comprehensively reflect the major influence factors and hazard degree of coal and gas outburst in Nanshan MineThe comparison of electromagnetic radiation indexes and conventional indexes in a coal and gas outburst coal face in Nanshan Mine indicated that the electromagnetic radiation indexes are basically corresponding to and consistent with the conventional indexes of drilling cuttings gas desorption index Δh2 and drilling cutting amount S, but is worse consistent with the initial velocity q of gas emission from boreholes. So comprehensive prediction can be made on coal and gas outburst hazard in Nashan Mine with the combined method of drilling cutting amount S, drilling cuttings gas desorption index Δh2 and electromagnetic radiation index.
