浅埋深薄基岩三软易自燃厚煤层防灭火技术
Fire Prevention Technology for Shallow Buried Depth Thin Bedrock Three Soft Easy Spontaneous Combustion Thick Coal Seam
摘要
Abstract
In this paper, taking Yixin coal 2102 working face as the background, by means of theoretical analysis and field practice, fire extinguishing technology for shallow buried depth and thin bedrock and easy spontaneous combustion coal seam is studied. The prevention of coal spontaneous combustion in goaf is mainly aimed at the spontaneous combustion zone. As long as one or more of the four conditions causing coal spontaneous combustion are eliminated and the coal oxidation reaction is terminated, the coal spontaneous combustion can be prevented. The"five-step tillage"and"four-procedure"treatment technology and downhole comprehensive fire prevention technology have been implemented in the ground subsidence area, which can effectively control the excessive CO gas in the coal face.分类
