复杂难采高瓦斯煤层简易放顶煤开采综合防灭火技术研究

Study on Comprehensive Fire Preventing and Extinguishing Technique of Simple Cutting Top Coal Dropping of Complicated and Difficult Cutting Coal Bed with High Gas

笔者在分析淮南矿区复杂难采高瓦斯煤层简易放顶煤开采工作面自然发火时空特点基础上 ,提出建立一套预测、预报、预防和充分准备灭火的防灭火体系 ,并阐述了预测、预报、预防的实施方法。该方法应用于淮南矿区 ,成功地开采了数个简易放顶煤工作面 ,综合防灭火技术取得了较好经济和社会效益。

Based on the analysis of self-ignition characteristics at the working face in Huainan mine, a fire prevention and fully prepared extinguishment system including fire prediction and forecast was established, and their implementation methods described. The system has been successfully practiced at several working faces in Huainan mine with satisfactory social and economic benefit.
