2 When the vein is discontinuous and along the strike, the tendency is not extended. When the ore is of high value and the ore is relatively stable, the column and the artificial column are not left. When the length of the vein exceeds 200m , one should be kept every 100m~120m. Pillars, and measures for the goaf should be developed;
3 When the veins along the strike appear branching veins, the pillars should be left at the branch or intersection, and a shared patio or shared funnel should be provided. The main veins and branch veins should be harvested at the same time;
4 Parallel veins alternately appear on the vertical section. When the distance between the two veins is less than 1.5m , the original stope can be gradually transitioned to parallel veins at an inclination angle of 60° . When the spacing is 1.5m~3.0m , it should be parallel to the mining work. Dig the 60° inclined funnel, and should continue to pick up after the second cutting; when the spacing is greater than 3.0m , it should be separately opened in the blind stage.
The 1 very thin ore vein retention method should be applied to the steeply inclined vein with an average thickness of less than 0.8m , and the sampling width should be controlled from 0.9m to 1.1m ;
