易自燃煤层大采高工作面CO异常超限防治技术实践

摘要

羊场湾矿现采2#煤层为高韧性易自燃煤层，在回采过程中，实施以管风防火为主，注氮、灌浆等为辅的综合防灭火措施，在防治煤炭自然发火方面取得了一定的成绩。本文通过对120201大采高综采工作面CO异常超限处理进行总结和分析，旨在探索解决易自燃大采高工作面CO异常超限的处理途径。%Yangchangwan Mine 2# coal seam is spontaneous combustion coal for high toughness. In the mining process, the fire prevention measures of wind pipe preventing fire as major, and combined with nitrogen injection and grouting are implementated. And it has made certain achievements to prevent and control coal spontaneous combustion. This paper analyzes the 120201 large mining height fully mechanized working face of CO abnormal excess treatment, aims to explores the approaches to solve CO abnormal excess of the working face with large mining height of spontaneous combustion.
