The advantage of the box bracket filling method is that the ore depletion rate is small and the recovery rate is high; the method is flexible and adaptable, and the surface collapse can be prevented.
Our Yunnan Tin companies use the box bracket filling method has a wealth of experience, particularly experience in the construction of the blocks, bedding methods, mining sequence, etc., have more in-depth research and successful. This method has played a big role in the history of mining tin mines in China.
However, this method is labor intensive, complicated in process, low in labor productivity and nugget production capacity, high in pit wood consumption, and high in mining cost. Due to the development of the mining industry, it is now possible to replace the box-supporting method with a mining method with higher efficiency, less wood consumption and lower labor intensity, and the number of mines that continue to use this method has been greatly reduced.
