February 20, 2024

The sublevel caving method of vertical falling ore is basically the same as the typical sublevel caving method of horizontal falling ore. The difference is that the former is divided into ore blocks by electric ramp, while the latter is controlled by horizontal deep holes. To divide.
  (1) Stage height - 40 to 60 meters.

(2) Section height - 10 to 25 meters (determined by the ability of rock drilling equipment)

(3) The height of the sub-column of the section - 6 ~ 8 ~ 11 meters.

(4) Length of the nugget - 25 to 30 meters (equal to the spacing of the veins) (arranged along the strike)

(5) Width of the nugget - 10 to 15 meters (the thickness of the ore body when placed along the strike)
