上榆泉煤矿综放工作面采空区"三带"划分实践及防灭火技术
Practice and Fire Prevention and Extinguishing Technology of"Three Zones" Division in Goaf of Fully Mechanized Caving Face of Shangyuquan Coal Mine
摘要
Abstract
In order to accurately divide the distribution laws of "three zones" in goaf of No.10 coal seam fully mechanized caving face in Shangyuquan Coal Mine, taking I031001 fully mechanized caving working face as the research object, measuring points are arranged along the full section of the working face to observe the gas change law of goaf O2, CO, CO2 and CH4 with the advancing of working face, and carry on the summary analysis. The concentration of oxygen is utilized as division indicators to separate the width of spontaneous combustion "three zones" in goaf. According to shortest spontaneous combustion period, the minimum safe advancing speed is calculated. Comprehensive fire-prevention measures such as grouting, nitrogen injection technology and air leaking control are proposed by the combination of the actual condition of this mine.关键词
