(4) Selection of skip for main shaf

(4) Selection of skip for main shaft hoistingThe lifting container should be determined according to the size of the lifting task. According to the specific situation of the mine, increasing the lifting container can reduce the lifting speed. The lifting machine and shaft equipment should be increased, increasing the initial investment, but saving electricity. On the contrary, if the lifting speed is increased, smaller lifting containers and hoists can be selected, with less investment but higher power consumption. It is generally believed that on the premise of not increasing the diameter of hoist and shaft, a larger hoisting container should be selected to adopt a lower hoisting speed and save power consumption. [4] the mine main shaft adopts skip hoisting, the main parameters are as follows:
