自燃发火条件下近距离煤层群开采火灾防治技术的研究

Study about Fire Extinguishing Techniques of Close-range Coal-seam Group Mining under Natural Combustion Condition

火灾一直是困扰煤矿安全生产的主要因素之一,特别是内因火灾的防治,是当今高突矿井的重点、难点工作之一。针对乌达矿区煤层层间距小、瓦斯含量大、受自然发火的影响等问题,分析了近距离煤层开采过程中工作面火灾防治技术,提出了一套切实可行的安全回采技术和措施,通过实施该套火灾防治技术和措施,有效防止了煤层自燃,实现了矿井安全生产。

The fire has been one of the main factors that influences coal mine's safety production,especially the fire prevention because of internal cause is the focus and difficulties of today's high outburst mine.Aiming at the problems of coal seam's small space of Wuda mining area,high gas content,and naturalspontaneous combustion,the paper analyzes fire prevention and control technology of working face in the process of close-range coal-seam's mining and puts forward to a set of feasible and safe stoping technology andmeasures,through the implementation of the fire prevention technology and measures,which effectively prevents spontaneous combustion of coal-seam,and realizes safety production the coal mine
