摘要
矿井回采完毕后老空区周边巷道密闭因为长期挤压变形产生漏风现象,对漏风点的准确定位可有效防止老空区漏风产生的自燃火灾现象。本文以古书院煤矿153303老空区为研究对象,采用气体示踪法检测该区域密闭是否存在漏风通道,示踪气体为SF_(6)。研究结果表明测试区域存在3个漏风点,结合漏风情况制定了防止老空区自燃措施。本文研究成果对于其他老空区漏风点的确定提供了合理有效的检测方法。
After the completion of the mining,the surrounding roadway of the goaf is closed because of the longterm extrusion deformation,resulting in air leakage.The accurate positioning of the air leakage point can effectively prevent the spontaneous combustion fire caused by the air leakage in the goaf.In this paper,the 153303 goaf of Gushuyuan Coal Mine is taken as the research object,the gas tracer method is used to detect whether there is air leakage channel in the closed area,and the tracer gas is SF6.The results show that there are three air leakage points in the test area.Combined with the air leakage situation,the measures to prevent spontaneous combustion in the goaf are formulated.The research results of this paper provide a reasonable and effective detection method for the determination of air leakage points in other old goafs.
