摘要
以山西晋城矿区寺河矿3313回采工作面为对象,研究了该采煤工作面每日进尺、通风等因素对采动L型井甲烷的流量、浓度、纯量的影响。数据表明,采煤工作面进尺量与L型井抽采甲烷纯量呈正相关;井下高抽巷风排甲烷量与L型井抽采甲烷量呈负相关。
Based on the 3313 mining face of Sihe coal mine in Jincheng mining group, Shanxi Province, the effects of daily footage, ventilation and other factors on the flow, concentration and pure methane in L-shaped drainage borehole were studied. The data show that the mining footage is positively correlated with the methane extracted by L-shaped wells;the methane drained from underground special tunnels is negatively correlated with the L-shaped drainage wells.
