基于等效Y型通风策略的综合瓦斯治理研究

Research on comprehensive gas control based on equivalent Y ventilation strategy

受隅角处瓦斯积聚现象的影响,麻家梁煤矿内的高瓦斯工作面出现了超限的状况,为解决该问题,本文选定该矿某工作面作为对象进行了针对性研究,经过深入分析过该工作面隅角瓦斯的具体来源,确定了一个综合性的治理技术,该技术主要是对通风系统进行调整,利用倾斜风障以及设置在回风巷内的增压板闭和联络巷内的预埋管等装置改变其通风情况,调整后的系统风流表现为Y型,上隅角区域的风向由之前的出风转成进风。

the influence of corner gas accumulation phenomenon, high gas working face Majialiang coal mine in the overload situation, in order to solve this problem, this paper selected a working face in the mine as the object to study, through in-depth analysis of the specific source of the working face of the corner gas, the author determined the treatment technology of a comprehensive, which is mainly used to adjust the ventilation system, using the pressure plate and is arranged in the inclined windbreak in close contact and return air Lane Lane of the buried pipe device changes its ventilation system, after adjusting the airflow performance for Y type, the upper corner of the area by the wind before the wind turned into the wind.
