【摘要】：基于淺埋藏煤層采空區(qū)受地表裂隙誘導漏風的影響,從采空區(qū)煤自燃防治為出發(fā)點,以磁窯溝煤礦10_(-2)號煤層10202工作面為研究對象,通過采空區(qū)鋪設(shè)束管觀測系統(tǒng),輔助測點的氧氣濃度變化,分析了淺埋藏工作面采空區(qū)氧氣濃度變化規(guī)律,得到了采空區(qū)自燃氧化區(qū)域的分布特征。通過采空區(qū)自燃氧化三帶的實測分析,掌握了磁窯溝淺埋藏工作面自燃氧化區(qū)域分布及最低推進速度,有助于指導礦井的防滅火實踐。
[Abstract]:Based on the influence of air leakage induced by surface fissures in the goaf of shallow buried coal seam, starting from the prevention and control of spontaneous combustion of coal in goaf, taking the No. 10 coal seam 10202 face of Ciyaogou coal mine as the research object, the observation system of beam tube is laid in the goaf. The variation of oxygen concentration in the goaf of shallow buried working face is analyzed, and the distribution characteristics of spontaneous combustion oxidation zone in goaf are obtained. Through the measured analysis of the third zone of spontaneous combustion oxidation in goaf, the variation of oxygen concentration in the goaf is analyzed. The paper grasps the distribution of spontaneous combustion oxidation zone and the lowest speed of propulsion in shallow buried face of magnetic kiln ditch, which is helpful to guide the practice of preventing and extinguishing fire in mines.
