一个采煤工作面,不论采用什么开采方法,运输设备一般安装在进风巷道内。普采工作面的顺槽内只有运输设备;而综采工作面除了运输设备外,还必须有移动变电站和乳化液泵站。这些设备的体积都很庞大,一字形排列开,全长有五十米左右,如果与运输设备同放在一条巷道内,这个巷道断面将增大很多,不仅增加了投资,巷道维护也将非常困难,否则就需另开一条专供存放设备的巷道。
A coal mining face, no matter what mining methods are used, transport equipment is generally installed in the inlet airway. Pug mining face along the trough only transport equipment; and fully mechanized mining face in addition to transport equipment, but also must have a mobile substation and emulsion pump station. These devices are very bulky, arranged in a zigzag pattern, the total length of about 50 meters, and if the transport equipment with a laneway, the laneway section will increase a lot, not only increased investment, roadway maintenance will also be very Difficulty, otherwise you need to open another dedicated to the storage of equipment roadway.
