In the middle of the 7C 80m wide ore body, two layered roadways are excavated, and a 4m wide pillar is left between the two roadways. The recovery road is taken from the layered roadway to the upper or lower plate. The approach is to recover from the layered roadway 4Â°ï½ž5Â° downward to achieve the purpose of filling the top. Mining and mining with trackless equipment such as scrapers. After the end of mining, install the Ñ„159mm filling pipe to the top plate of the road, and use a short wall (within 30m) to hit a partition wall. The long-distance road will be used to drive a partition wall every 20~30m. Each section will be charged for 4~5 hours. Then fill the outside of the road. Later, the method of improving the segmented borehole filling method was successful, and the filling cost per cubic meter could be reduced by 0.85 to 0.95 rubles (see Figure 1).

QUANTUM En Masse and Drag Chain Conveyors are used to convey powdery and granulated products across a range of inclined and vertical installations.
QUANTUM utilizes drop-forged links with case hardened pins, or standard conveyor chains depending on the material to be conveyed & the application.
The conveyor length is limited by the capacity and chain speed, but lengths of 100m and more are not uncommon, with capacities over 600t/hr.
The standard range of QUANTUM En Masse Conveyors comes in 2 grades:
â€¢ Light: (QCL Range, specifically designed for typical products Grain , flour, stock feed pellets, paper, pulp-> Specific gravity 750kg/m3)
â€¢ Heavy: (QCH Range, specifically designed for Cement, fly ash, sand, woodchips, biomass, coal powder -> Specific gravity 1500kg/m3)
All ranges span from 190-1000mm wide, come with single or dual chain options and have a variety of standard attachments to suit the application. For Bin discharge, we provide multiple strand chain & specially designed hoppers for constant & even emptying.
QUANTUM can provide customized designs, including for high temperature applications and all conveyor arrangement can be designed into horizontal or inclined layout.
