矿井综放开采工作面瓦斯涌出来源与分布规律分析

Analysis of Gas Emission Sources and Distribution Law in Fully Mechanized Caving Face

以某矿31101综放工作面回采为工程实例,根据已有资料并结合矿井采掘期间煤层瓦斯含量测定结果,对该矿11号煤层瓦斯含量随埋深变化情况进行预测,分析采面瓦斯涌出来源,并根据现场实测结果分析采面瓦斯分布规律,为后续采面瓦斯治理提供经验借鉴。

Taking the stoping of 31101 fully mechanized top coal caving face of a mine as an engineering example,according to the existing data and combined with the measurement results of coal seam gas content during mining,the gas content of No.11 coal seam in the mine is predicted with the buried depth,the gas emission source of the mining face is analyzed,and the gas distribution law of the mining face is analyzed according to the field measurement results,so as to provide experience and reference for the follow-up mining face gas control.
