阳煤集团综放工作面自然发火防治技术应用的研究

Study on Application of Spontaneous Combustion Prevention Technology in Fully Mechanized Caving Face of Yangmei Group

阳泉矿区是我国典型的高瓦斯区域,随着煤矿生产技术和瓦斯治理技术的发展,治理瓦斯水平提升到了一个新的水平,保证了回采工作面推进加快、单产水平不断提高。但是,工作面防治自然发火的技术研究没有跟上安全发展的需要,导致近年来煤层自燃的事故有上升的趋势。因此,针对阳泉矿区存在的瓦斯与火共存问题,对井下火灾的主要发生原因进行分析,找出15#煤自然发火规律、自燃特点,研究灭火技术及装备,提高灭火效果,成为煤矿保证安全生产的需要。

Yangquan mining area is a typical high-gas area in China.With the development of coal mine production technology and gas control technology,the gas control level has been raised to a new level,which ensures the acceleration of the working face and the continuous improvement of the yield per unit area.However,the technical research on the prevention and control of spontaneous combustion in working face failed to keep up with the needs of safe development,which led to an upward trend in coal seam spontaneous combustion accidents in recent years.Therefore,aiming at the coexistence of gas and fire in Yangquan mining area,it is necessary to analyze the main causes of underground fire,find out the spontaneous combustion law and characteristics of 15#coal,and study fire extinguishing technology and equipment to improve fire extinguishing effect.
