2 The order of returning the ore and caving surrounding rock by the wall-filling mining method shall be determined according to the stability of the ore. When the stability of the surrounding rock is good, it is better to mine the rock and then collapse the surrounding rock. When the stability of the surrounding rock is poor, the surrounding rock and the rear ore should be collapsed first;
3 When mining steeply inclined ore bodies, the cutting plates or cushions shall be laid before the mining site collapses;
4 When mining gently inclined veins, the large amount of waste rock is used to build the retaining wall to the top of the stope. The distance from the retaining wall to the working surface should not exceed 2.5m .
What requirements should be met in the method of cutting wall filling mining?
1 The wall-filling mining method should be applied to extremely thin veins with stable shape, clear ore and surrounding rock boundaries;
