东川矿务局因民矿张口硐溜矿井全长275米,井径2.3米,岩石硬度8～10级。其主要经验是:1.推广使用双活动吊盘(即上、下层吊盘),上吊盘作为工作吊盘,下吊盘作为保护吊盘,以防止工具和松石掉下伤人。2.使用活软梯子。活软梯子系用5/8圆铁做成,每节长0.4米。使用软梯子不仅在挂吊盘时省力,而且对工作人员上下的安全也有很大的保证。3.铁道保护品。为了节省木料,保护台用长短不一的8公斤重的铁道做成。在铁道之间铺上木板不仅安全,而且搬移保护道时也很方便。
Dongchuan Mining Bureau due to the mines Zhang mouth hole sloping mine a total length of 275 meters, diameter of 2.3 meters, rock hardness of 8 to 10. Its main experience is as follows: 1.
