自燃煤层窄煤柱综采工作面综合防灭火技术

Comprehensive Fire Prevention and Extinguishment Technology of Spontaneous Combustion Coal Seam in Fully-mechanized Coal Face with Narrow Coal Pillar

分析了窄煤柱开采条件下,自燃煤层综采工作面容易发生自燃的地点及引起自燃发火的因素,介绍了针对以上地点不同的发火因素,所采取的包括均压灭火、埋管灌浆、注水、顶板走向钻孔灌浆等综合防灭火技术的应用及取得的效果。

It analyzes the easily spontaneous combustion places and their corresponding factors in fully - mechanized face under the narrow coal pillar mining condition. Then it introduces the application and the effect of the comprehensive fire prevention and extinguishment technology including the balance fire - extinguishing, the grouting with installed pipe, the effusion, and the grouting with drills along roof strike, and so on, in view of different kinds of self- igniting factors in different ignition places.
