When mining steeply inclined veins, the transportation roadway in the lower part of the ore block can be used along the vein prospecting roadway: the uphill mountain can be arranged on one side or the center of the ore block, and the width of the bottom roadway should not be too large, as long as the width of the stope is reached and it is easy to excavate; ore The number and location of the chutes are determined according to the way the ore is transported; if there is a waste rock released during the mining process, a waste rock chute should also be set up.
When mining the gently diverted veins, the transportation roadway should be excavated in the lower rock to meet the requirements of the mining; the underground roadway is to be driven in the lower part of the mine. When the wall working face mining plan is adopted, the mountain is used as the cutting mountain or special excavation. Cutting up the mountain; the ore-sliding well depends on the structure of the stope.
This station is suitable for industrial, civil construction, roads, railways, bridges, electric power, water conservancy, port terminals, airports and other projects. It can be used as a mixing equipment for commercial concrete production, and combined various forms different specifications concrete mixing plant according to the needs of different users.
