Application and analysis of the skip in the vertical shaft development

Based on the underground mining of depth ore body with small scale, according to the vertical shaft development system, this paper verifies the optimal solution of the selected scheme by comparing different schemes of multi-rope flip skip and single-rope flip skip, makes in-depth comparison from two aspects of comparable investment and economical analysis,the multi-rope scheme is verified the better one. Analyze and study the most unfavorable operating conditions of the flipping skip system during operation, point out the disadvantages of the selected scheme, the use of heavy （balance） tail rope method to solve the slippage problem is proposed, and conduct reliability analysis, as well as the energy-saving advantages in the heavy tail rope system.
