The main advantages of eDonkey transportation are:
(1 ) The equipment has simple structure, easy processing and manufacturing, low equipment cost, and low investment in mine infrastructure;
(2 ) The roadway section is required to be small and the tunneling cost is low. Especially when the rock is not stable and the large section roadway is restricted, it is especially suitable to use the electric raft.
(3 ) The equipment is sturdy and durable, easy to maintain, and can be carried out on site, with low maintenance costs;
(4 ) The equipment has a good rate of completion, as long as the preventive maintenance is simple, the equipment integrity rate can reach more than 95% ;
(5) The operation is simple and easy, the technical requirements for workers and managers are low, and it can be operated and operated after simple training;
(6 ) The cost of ore transportation is low.
The main disadvantages of electric picking and transporting are: poor maneuverability of the equipment, large wear of steel ropes, large electric energy consumption, and a significant drop in production capacity when the ore is prone to increase in powder transport distance.
Electric rafts are currently being developed into large-scale ( over 1m3 capacity , winch power above 100kw ) and remote control to further improve their production capacity and safety.
Application and evaluation of electric transport
Electric raft transportation is a main method for mining and mining. It can be applied in most mining sites of various mining methods. Some mines directly mine from the mining face, and some mines from the electric roadway. The application of shovel in various mining methods.
