摘要
在松散煤体中掘进巷道,自然发火防控难度大,存在漏风范围大、自燃隐患点不确定等难点。本文通过制定实施科学有效的防灭火安全技术措施,形成了适合大统矿业C9301工作面松散煤体中掘进预防自然发火的综合防控技术,保障了矿井安全生产,提高了矿井经济效益。
It is difficult to prevent and control spontaneous combustion when driving roadway in loose coal mass,such as large air leakage range and uncertain potential point of spontaneous combustion.In this paper,through the formulation and implementation of scientific and effective fire prevention and control measures,formed a comprehensive prevention and control technology suitable for Datong Mining C9301 working face in loose coal to prevent spontaneous combustion,which ensured the safety of mine production and improved the economic benefits of the mine.
