在大、中型煤矿的生产中,矿井的主要运输大巷内均安装有必备的洒水降尘装置。但是,该装置的控制系统不完善,导致井下电机车在往返运行中存在着极大隐患,例如:当电机车通过水幕时,水幕未能及时关闭,可能造成电机车架空线的电压通过水幕与电机车的其它金属部分带电,容易造成人身
In the production of large and medium-sized coal mines, the mine’s main transport lane are equipped with the necessary sprinkler dust control device. However, the control system of the device is imperfect, which leads to the great hidden danger of the underground electric locomotive running back and forth. For example, when the electric locomotive passes the water curtain, the water curtain can not be shut down in time, which may cause the voltage of the overhead line of the motor vehicle to pass Water curtain and other parts of the electric car charged, likely to cause personal
