(1) Meet the stability requirements During the entire mining process of the ore block, the stability of the bottom column should be ensured, so that the collected ore is released according to the planned amount of ore. When the ore is unstable, there will be a bottom collapse, such as blockage of the electric ramp, collapse of the ramp, etc.; (2) The bottom structure is simple, the construction is convenient, and the mining is convenient. (3) Under the premise of ensuring the stability of the bottom column, the amount of bottom column should be minimized to improve the total recovery rate of the ore block. (4) It can guarantee the safety and good working conditions of mining, secondary crushing and transportation. (5) Large mining capacity and improve the efficiency of mining methods.
