摘要
针对肖家洼煤矿110805工作面瓦斯涌出开展预测,并分析各涌出源的瓦斯构成,制定出有针对性瓦斯治理方案,即采用迈步埋管配合高位钻场同时抽采工作面采空区、回风隅角瓦斯等措施,从而保障了工作面的安全高效生产。
According to the prediction of gas emission in 110805 working face of Xiaojiawa Coal Mine,the gas composition of each gas emission source was analyzed,and the targeted gas control scheme was worked out,that is,the gas in goaf and return-air corner of working face is extracted simultaneously by step buried pipe with high-level drilling field,so as to ensure the safe and efficient production of working face.
