摘要

鸿森煤矿在回采过程中发现2503工作面采空区发生煤层自然发火,该矿采取了密闭墙密闭工作面的灭火方法,但受顶板条件及施工质量影响,该工作面仍存在漏风现象及火灾威胁。为彻底消除火灾灾害,保证矿井安全生产,采取向工作面注水的灭火方法,取得了较好的效果。
        During the mining process of No. 2503 working face in Hongsen coal mine,the coal spontaneous combustion occurred in the goaf. The fire extinguishing method of sealing working face by closed wall was used. Due to the influence of roof condition and construction quality,there was still air leakage and fire hazard in the working face. To thoroughly solve the problem and ensure safety production,water injection fire extinguishing method was adopted,and good results were achieved.
