[0040] Implementation case:
[0041] The gently sloping medium-thick ore body is produced in a layered like layered form. The inclination angle of the ore body is 5-20°, the thickness is 10-16m, and the strike length of the ore body is 755-890m. The ore rock in this mining area has good stability. , The mining of ore bodies is less affected by groundwater, and the engineering geological conditions are of medium type.
[0042] Accuracy and cutting: such as figure 1 , 2 , 3 and 4, the gently inclined medium-thick ore body is divided into panels, and the ore bodies in the panel are divided into strips along the direction of the ore body, that is, the strips in the panel are divided into one-step stope 11 and Two-step stope 10, every 12 stopes are used as a panel, and a panel exit chute 3 is arranged on the bottom side of the panel. The lower part of the panel chute is connected to the vein-through roadway 16, and the vein-through roadway 16 is connected to the middle section of the tr...
