Structural parameters of the wall-filling mining method

Since the thin veins occurrence condition changes, complicated mining conditions, the height of the stage should not be too large, it is generally 30 ~ 40m; ore mining ore block length depending on the field of haulage method using mechanical haulage, press apparatus The effective transportation distance is determined: when the ore is transported ore, the one-way transport is 25 ~ 30m ; the two-way transport is 50 ~ 60m ; the scraper can take 75 ~ 150m when transporting the mine ; generally there is no column, the height of the bottom is 2 ~ 4m , when the ore is a high-priced ore with high grade, the artificially built reinforced concrete bottom column or wooden shed bottom column is often used instead of the ore bottom column. The thickness of the top column depends on the stability of the ore and the mining method, generally 2 ~ 4m ; The stratification height depends on the mining conditions of the ore, and the variation is in the range of 0.5 to 1.5 m . When the ore spacing is used, the transportation distance is not more than 7 to 8 m , and the transportation can be increased by using the trolley. 30m .
