栖霞山锰矿为了使井巷掘进的装岩工放下扒子簸箕,自己动手,从实际出发,试制成功一种装岩设备——巷道皮带装岩机。用它装岩,工人的劳动强度大为减轻,而且工效大为提高。过去手工出碴一次放炮的碴(巷道断面3.8米~2,进尺1.2米),需2名工人、4小时才能完成。现1人操作手扶耙斗,2小时就可耙完。由于装岩时间缩短,每班的作业循环由过去1个增加到2个,使掘进速度提高1倍以上。
Qixiashan manganese ore tunneling in order to allow the installation of rock masonry down platter dustpan, do it yourself, starting from the actual trial of a successful installation of rock equipment - roadway belt rock loader. Use it to rock, greatly reducing the labor intensity of workers, but also greatly improved work efficiency. In the past, one ballast was shot manually (the tunnel section was 3.8m ~ 2 and the footage was 1.2m) and 2 workers were required to complete the work in 4 hours. Now 1 person operating hand rake bucket, 2 hours can rake finished. Due to the shortened rock loading time, the operating cycle of each shift increased from the previous one to two, which enabled the excavation speed to more than double.
