摘要
矿井现主采的3-1煤层为容易自燃,在收作过程中由于地质构造影响往往会留顶煤,给收作防火管理带来难度。本文通过对113102收作面留顶煤收作期间,防灭火技术进一步研究分析,采取一系列措施,有效控制了易自燃厚煤层留顶煤收作自燃发火事故,确保工作面安全收作,也为今后防灭火工作总结了经验。
The main 3-1 coal seam is easy to spontaneous combustion.Top coal is often retained due to the influence of geological structure in the harvest process,which brings difficulties to the fire prevention management of harvest.Through further research and analysis of fire prevention and extinguishing technology during the period of roof-retaining coal harvesting in 113102 harvesting face,a series of measures have been taken to effectively control the Spontaneous Combustion Accident of roof-retaining coal in thick spontaneous combustion seam,ensure the safe harvest of working face,and summarize the experience for future fire prevention and extinguishing work.
