主井提升能力的合理确定，可以最大限度发挥提升机的能力，为生产管理提供最佳生产方案，也可以给设计提供最佳选型方案，减少盲目投资。 目前，年生产能力的计算方式分为以下几步：根据年产量Ａ、井深度Ｈ及设备工作制度，确定合理的经济速度Ｖ；估算一次提升的合理重量，选箕
The main shaft to enhance the ability to determine a reasonable, you can maximize the capacity of the elevator to provide the best production management program, but also to provide the best design selection program to reduce blind investment. At present, the calculation method of annual production capacity is divided into the following steps: According to annual output A, well depth H and equipment working system, to determine a reasonable economic speed V; Estimate a reasonable weight to enhance, choose Kei
