简放工作面供风量与采空区遗煤自燃危险性研究

针对地方煤矿易自燃厚煤层简易放顶煤开采推进速度低的现实条件,本文在分析不同氧浓度条件下煤的耗氧速度、采空区煤氧化自燃三带及其与采空区漏风量关系基础上,研究了工作面供风量与漏风量及其采空区氧化带宽度的关系,研究结果为厚煤层简放开采工作面的合理供风量及防治煤炭自燃措施应用提供了技术依据.

Research on the air supply volume during simple cutting of top coal dropping and the coal spontaneous combustion in the goaf

In response to the actual situation of the low advance rate of working face in the thick coal seam inclined to spontaneous combustion,based on the analysis of oxygen consumption velocity under the condition of different oxygen concentration and the relationship between the tri-zone of coal spontaneous combustion and the air leakage in the goaf,the relationship between air leakage and supply volume in the goaf and the width of the oxidation zone is researched in this paper.The research results provide the te...
