摘要
矿山提升机是矿山大型固定机械之一,矿山提升机从最初的蒸汽机拖动的单绳缠绕式提升机发展到今天的交——交变频直接拖动的多绳摩擦式提升机和双绳缠绕式提升机已经历了170多年的发展历史,它是矿山井下生产系统和地面工业广场相连接的枢纽,被喻为矿山运输的咽喉。因此矿山提升设备在矿山生产的全过程占有重要的地位。根据矿井提升机工作原理和结构的不同,可分为缠绕式提升机和摩擦式提升机。
在国内外,多绳摩擦式绞车飞跃发展,其发展速度远远超过单绳缠绕式提升机,这是因为它有着许多单绳缠绕式提升机无法比拟的优点,如提升钢丝绳直径较小,主导轮直径及整个机器的尺寸都相应缩小了,设备重量也减轻了,不需要设置防坠器等。
下面是我针对不同的矿井的地质、煤层等情况,进行综合计算分析后,本着安全、经济等原则对这两种提升设备系统进行的选型设计。一个现代化的矿井在提升设备的选型上尤为重要。因为提升设备选型的合理与否,直接关系到矿井的安全和经济性,因此确定合理的提升系统时,必须经过多方面的技术经济比较,结合矿井的具体条件选择合适的设备。

Abstract
The mine elevator is one of mine large-scale fixed machineries, the mine elevator the winding type elevator developed from initial steam engine dragging's Shan Sheng to today's junction - - hands over the frequency conversion direct dragging the multi-rope friction type elevator and the double rope winding type elevator has experienced more than 170 year historical developments, it was the key position which the mine shaft production system and the ground industry square connected, is explained for mine haulage's pharynx and larynx. Therefore the mine hoisting equipment holds the important status in the mine production's entire process. According to the mine pit elevator principle of work and the structure difference, may divide into the winding type elevator and the friction type elevator.
In domestic and foreign, the multi-rope friction type winch leap development, its development speed goes far beyond the single rope winding type elevator, this is because it has the merit which many single rope winding type elevator is unable pare, like the hoisting cable diameter was small, leads the wheel diameter and the entire machine's size correspondingly reduced, the installation weight also reduced, did not need to establish against falls and so on.
Below is I in view of different situations and so on mine pit geology, coal bed, after carrying on the putation analysis, in line with principles and so on security, economy the shaping design which carries on to these two kind of lift techn
