Abstract:
Sincea bucket hoist systemcan not satisfy efficient construction in mine construction stage,a mixed lifting scheme ofdouble cage with double skipin temporary change twist period isproposed.By computing and security check,equipment selection programis determined that the cage hoisting system uses a 18 × 7-28-1770 wire rope,TXG2000/28-type steel sheave,2JK-2.5/20-hoist,skip hoisting system uses2JK-3.5/20 hoist.,and its lifting capacity were calculated too.The results show that a mixed lifting scheme ofdouble cage with double skip in temporary change twist period can significantly increase lift capacity,shorten the construction cycle by six months,bring considerable economic benefits,and provide the theoretical basis and scientific support fora coal mine shaft hoist system construction.
