摘要
基于沙曲矿系高瓦斯矿井,(其14205工作面有上下邻近层及邻近采空区),采空区瓦斯涌出达60%以上,易使综采面瓦斯浓度超限,影响工作面的安全生产。针对性地研究了综采面瓦斯浓度分布规律,对综采面瓦斯治理和瓦斯涌出量预测均有重要的意义。
Shaqu Mine is a high gassy mine (its 14205 working face has up-down adjacent layers and adjacent gobs). The gas outflow from the gobs is above 60%, which will cause the gas ultra-limit in entry comer and threaten the safety in work faces. The study on gas concentration distribution law is important to the gas control and prediction of its emission volume in fully-mechanized mining working face.
