摘要
针对高瓦斯矿井在工作面掘进期间易出现巷道瓦斯浓度超限的情况,通过对大水头煤矿中105综放工作面施工现场进行瓦斯监测,分析巷道工作面和巷道壁的瓦斯涌出规律,找到影响掘进巷道瓦斯超限的主要因素。根据瓦斯涌出规律进行施工,保证掘进生产安全。
Based on roadway gas concentration overrun easily appearing in high gas mine working face mining, through gas monitoring in 105 fully mechanized caving face site of Dashuitou Mine, gas emission regularity of working face and tunnel wall were analyzed, main factors affecting roadway gas overrun in mining were found out. According to the law of gas emission in the construction, ensured the mining production safety.
