摘要:
为探明羊场湾160205工作面上隅角CO体积分数超限明显的原因，沿工作面倾向和走向布置测点，测试早中晚三班开始前的CO体积分数，并在采空区布置束管，对不同位置气体进行取样分析，得出160205工作面CO体积分数分布。结合煤炭开采过程CO的主要来源与煤氧化产生CO的机理，分析得出羊场湾160205工作面CO主要来源。结果表明：CO体积分数沿工作面煤壁到架后采空区方向逐渐升高；采空区深度0~15 m和30~100 m处为高体积分数CO区域；160205工作面CO主要来源为采空区遗煤氧化，其次为顶煤氧化与割煤时煤体破碎产生，采空区深度30~100 m处的CO体积分数较高区域是判定采空区遗煤自燃状况的关键区域。
Abstract:
In order to find out the reason why the volume fraction of CO at the upper corner of 160205 working face of Yangchangwan exceeded the limit obviously,the measuring points were arranged along the tendency and strike of working face to test the volume fraction of CO before the start of the three shifts in the morning,noon and evening,and the bundle tubes were arranged in the goaf to sample and analyze the gas at different positions,then the distribution of CO volume fraction in 160205 working face was obtained.Combined with the main sources of CO in the process of coal mining and the mechanism of CO produced by coal oxidation,the main sources of CO in 160205 working face of Yangchangwan were analyzed.The results showed that the volume fraction of CO increased gradually along the direction from the coal wall of working face to the goaf behind the support.The positions at the depth of 0~15 m and 30~100 m in goaf were the areas with high volume fraction of CO.The main source of CO in 160205 working face was the oxidation of residual coal in goaf,followed by the top coal oxidation and coal fragmentation during coal cutting.The area with higher volume fraction of CO gas at the depth of 30~100 m in goaf was the key area to determine the spontaneous combustion status of residual coal in goaf.
