摘要
矿井火灾作为一大较为突出的灾害,对煤矿安全构成严重的威胁。为了研究煤矿井下巷道火灾封闭区内的燃烧状态,通过建立相似模拟实验台,模拟封闭火区的燃烧,了解火区封闭时期的燃烧状态,监测封闭区内各气体的成分、气体浓度变化情况,同时对区域内的气体、煤(岩)壁的温度变化趋势进行分析,以便推断火区封闭后的危险性,同时为救灾的安全性及火区的安全启封工作奠定基础。
As a more prominent disaster, the mine fire poses a serious threat to the coal mine safety. In order to study the combustion state in the closed fire area of coal mine roadway, establishes the similar simulation test bed, simulates the combustion of the closed fire area, understands the combustion state during the closed period of the fire zone, monitors the change of the gas composition and gas concentration in the closed area, in the meantime the temperature change of the gas and coal (rock) wall in the region is analyzed in order to infer the danger after the fire zone is closed, and lay the foundation for the safety of the disaster relief and the safety unsealing of the fire area.
