摘要
为了确定虎龙沟煤矿32~#煤层右十一工作面采煤机割煤速度与工作面瓦斯浓度的关系,通过现场观测,分析了工作面在经历过一个周期来压过程中不同割煤速度与瓦斯浓度的参数,拟合出瓦斯4个不同变化阶段内两者的二次函数关系式,对确定工作面瓦斯涌出及运移规律,并对工作面瓦斯治理进行指导,具有积极意义。
In order to determine the connection between the mining speed and the gas concentration in the working face in the No. 32 coal seam in Hulonggou coal mine,the data under different coal cutting speed and the gas concentration during the process of cyclic pressure are collected and analyzed on the base of field observation. The quadratic function relation between the coal cutting speed and the gas concentration within the four different stages of gas emission are simulated and fitted,the experience is of positive significance for the determination of gas emission and movement law in the working face,and provides guidance for the treatment of gas in the working face to provide a reference for determining the law of gas emission and migration in the working face. Work face gas governance provides guidance.
