Nugget composition of the wall filling method by dry filling method
The nugget composition of the wall filling method: (2) Patio spacing: generally 50 meters, the main reason for the use of small-sized mining areas is that the useful components in the extremely fine veins are generally unevenly distributed, and the ore bodies often have expansion and contraction along the strike and along the slope. The size of the area is not large, which is beneficial to better detect the condition of the vein at the time of picking. (4) The ore in the mining is left at a distance of about 10 meters (the time interval for manual transportation is small, and the spacing can be increased if the electricity is transported). We are a mold factory with over 20 years of experience. Our products are stable, corrosion-resistant, and very durable, and can be precision processed according to customized requirements.

(1) Stage height: generally less than 30 to 45 meters;
( 3) Generally, no top column, bottom column and inter-column are left, and the bottom column is mostly made of artificial bottom column (wood or concrete)
