摘要
针对端氏煤矿主采3号单一煤层厚、瓦斯含量高、突出危险性强,且不具备保护层开采条件等特点,提出建立合理的区域消突体系,以提高矿井的安全生产效率。根据矿井生产系统中各采掘地点的作业方式和生产布局,分别建立了石门揭煤、开拓大巷、回采工作面和煤巷掘进的区域消突技术,并进行了试验应用,确立了区域消突体系的效果检验方法及指标,经过现场实际考察,实测检验值均小于煤与瓦斯突出指标,验证了该区域消突体系的安全性和高效性。
In view of the client＇s main coal mine mining No. 3 high single thickness of coal seam gas content Outburst danger is strong, and do not have protective layer mining conditions, etc, proposed reasonable regional outburst elimination system thinking, to improve the safety of the mine production efficiency. According to the mine production system in the mining site layout mode of operation and production, established cross - cut uncovering coal development alleys Working face and regional outburst elimination technique of excavating in coal roadway, and has carried on the test application, established the effect of regional outburst elimination system inspection methods and indicators. Through the practical field investigation, the observed test values are less than coal and gas outburst index, validate the regional outburst elimination system security and high -efficiency.
