The mining of underground mines includes three steps: development, mining and mining.
Development is a mine’s infrastructure project. It connects the surface and the underground ore body with shafts and tunnels, and builds complete transportation, ventilation, and drainage shaft projects, including vertical shafts, inclined shafts, blind shafts, underground depots and various Use rooms, such as water pump room, transformer room, machine repair station, crushing room, gunpowder storehouse, etc., as well as stone gates, stage transportation lanes, chutes, etc. The mining standard is the free space required for the excavation of some roadways forming the shape of the mining test and for the drilling and blasting of the mining face. The former include transportation lanes, ventilation, and pedestrian patios in mining areas, and the latter include cutting grooves, bottom-drawing spaces, and ore-drawing funnels.
Stoping is to perform mining, loading and management operations on the mining face after the mining is completed.
Development, accurate mining, and stoping are important links in the entire underground mining. Among them, the loading process is the most arduous, time-consuming, and the link that has the greatest impact on mining production efficiency. According to the statistics. In the development of tunneling work. The amount of labor consumed in this process accounts for 30%-40% of the cycle time. In underground mining, loading operations also account for a large proportion.
