摘要
井工一矿19106工作面在回采过程中发现主回液管易爆管,严重影响工作面的正常生产,通过对19106综放工作面的主进、回液压力管路的压力损失分析,找到了爆管的原因,得到了工作面主进液压力损失比例,为工作面的高效生产做出了有效指导。
Primary return pipe is liable to explode in the mining on No.19106 fully-mechanized mining face in Jinggong No.1 Mine, which seriously threatens the normal production. On the analysis of pressure loss of pressure pipelines of main feed and return liquid, the paper finds out the cause of pipe explosion and pressure loss rate of the main feed liquid, which could provide guidance for the efficient production of the mining face.
