摘要
城郊煤矿2105综采工作面准备过程中,后期辅助工程存在4个掘进工作面相向掘进,通过采取构筑临时局部通风代替负压通风系统的措施,提高了掘进速度,加快了综采设备的安装进度,缩短了工作面接替时间。
The suburb coal mine 2,105 adopted the measure of constructing temporary partial ventilation replacing the negative pressure ventilation system through having 4 tunneling working surfaces in opposite direction tunneling in later period of assisted project during the preparation process of syntheses pick in the working surface, enhanced the tunneling speed, sped up the progress of the equipment installation for synthesis pick, reduced the time of the working surface replacement.
