Explosion Suppression Of The1203Sealed High Gas Goaf On Fire Of Xiangyuan Coal Mine

This article is based on the engineering background of explosion-proof technology research in the process of extinguishing of Xiangyuan coal mine goaf on fire in the high gas and easy spontaneous combustion coal seam. Along with the deepening of coal mining, mine gas and spontaneous combustion hazards are the important factors in the coal mine safety production and appear more and more at the same time, especially the mined-out area, to explore the management of high gas and fire area has practical significance. The Xiangyuan coal mine is the highly gassy mine and the coal seam of1203goaf is easily spontaneous combustion of coal seam. In order to ensure the safety of Xiangyuan coal mine1203mined-out area of coal combustion, ensure the safety of mine production, this article theory combined with practice, practice to explore gas explosion suppression in the high gas and easy spontaneous combustion coal seam fire area.At first, this paper sums up the law of the mine spontaneous combustion location, the theory of gas explosion and the management theory of fire area, secondly describes the basic situation of the Xiangyuan coal mine and1203working face, and then expounds the1203closed the goaf gas explosion accident and analyse each factor respectively from the explosion cause, with explosion triangle to explain the process, and then separately declare the fire extinguishing measures of obturation and the injection of nitrogen fire area and specific management measures on the spot, then the fire area monitoring data were analyzed to evaluate the effect of governance after adopting the measure, and finally provides a method that computer based on the analysis of monitoring data to determine the explosion.This study uses the theoretical analysis, field measurement, experimental determination, the methods of calculation and analysis, analyze the1203working face goaf gas explosion causes in the opening fire area process, made the1203working face explosion suppression measures, and on-site guide and implement the measure, evaluate the governance effect, acquire the good safety and economic benefits. At the same time this paper also gives an example dealing with goaf of coexistence of gas and fire.
