摘要
针对综放采煤工艺的采空区冒落空间大、采空区漏风量大、遗煤多、易自然发火的特点,从消除引发自然发火的主要条件出发,提出了在综放采空区内部构筑矸石凝胶隔离带的办法来消除自燃隐患,并对其防灭火效果进行了考察。为综放采空区的防灭火提出了新的技术手段。
Fully mechanized long wall top coal caving technology has characteristics as follow： large goaf space, large air leakage, a large amount of remnant coal and easy spontaneous combustion. By eliminating main conditions that cause spontaneous combustion, the method of building waste rock isolation wall in goal to eliminate fire hazard is put forward, and the fire control effect is investigated. It provides a new fire control technology for the goaf of fully mechanized top coal caving.
