综放工作面均压通风技术分析与应用

Analysis and Application of Pressure Balancing Ventilation Technology at Fully Mechanized Caving Face

以同煤集团同忻煤矿综放工作面为例,从实施原则、参数及设备选型、实施方法等方面建立均压通风安全技术体系。同时,通过多种技术的综合运用,提高均压通风可靠性。有效降低工作面CO下泄浓度,确保了工作面安全生产。

Take the fully mechanize caving face of Tongxin Colliery, Datong Mining Group Co., Ltd. as an example, the paper set up the equalized-pressure ventilation safety technical system from the aspect of implement principle, parameter and equipment selection, and implementation method. At the same time, by integrated using of different techniques, the reliability of equalized pressure ventilation was improved. The let down density of carbon monoxide in work face is decreased effectively, which ensured the safety production of the work face.
