1. The electric scraper is used to load ore and rock in the mine in full section, which is not limited by the operation width and transportation route; The loading width of the electric rock loader is only 2 m, and it needs to travel on the track. It is difficult to load ore beyond 1 m of the track. The advantage of the electric scraper is more obvious when mining in the mine room. The advantage of the electric rock loader is slightly higher than that of the electric scraper when tunneling.
2. The electric scraper can be used for shoveling and transportation within a range of 150 m. It is more convenient and efficient to load ore to the ore pass for unloading in a short distance. The electric rock loader can only be loaded into the ore car first, and then transported to the ore pass for unloading. The process is complex.
3. Each shift of electric scraper can draw 105t ore, while each shift of rock loader can draw 55t ore at most. The production efficiency of electric scraper is twice that of electric rock loader.
4. The loading of the electric rock loader is limited and restricted by the track, so the track needs to be added in time. In addition, the rock loader and tramcar fall off the track and go on the track, which affects the normal production progress. The electric scraper is not limited by the track and has strong continuous operation capacity, which is conducive to the improvement of production output.
5. The electric scraper can conveniently, flexibly and quickly handle the ores at the shoulder pillars, corners and blind areas of the mine room in a clean and thorough manner, and improve the recovery rate of ores.
6. The electric scraper can operate on the uphill and downhill conditions, which is conducive to the operation of gently inclined ore body, and can effectively improve the ore recovery rate and reduce the dilution rate.
