摘 要 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。 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。单绳缠绕式提升机是较早出现的一种，它工作可靠，结构简单，但是仅适用于浅井及中等深度的矿井，而对于井深超过300米的矿井，宜选用多绳摩擦式绞车。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。 本设计充分贯彻以下设计原则：根据国家现有的设备生产状况，结合某些使用中的具体情况，以及经济角度出发尽量选用国产设备并力求在条件基本相当的情况下进行技术的方案比较，选择即经济又合理的设备。 关键字：提升机、矿井、绞车Abstract A modern, upgraded equipment at the mine on the selection of particularly important. Since the rational selection of equipment to upgrade or not, is directly related to mine safety and economy, therefore, determine a reasonable upgrade system must go through a wide range of technical and economic comparison, combined with the specific conditions of mine appropriate equipment selection. Mine hoist in accordance with the working principle and structure of different type can be divided into the winding and friction hoist elevator. Coiled single-rope hoist is one of the first emergence of a kind of job it is reliable, simple structure, however, applies only to shallow and middle depth of the mine, while more than 300 meters for the depth of the mine, they are advised choice of multi-rope friction hoist. At home and abroad, multi-rope friction hoist leap in development, their development much faster than single coiled rope hoist, this is because it has a lot of single coiled rope hoist unmatched advantages, such as upgrading a smaller diameter wire rope, led wheel diameter and the whole machine size are corresponding to narrow, and equipment have reduced the weight, do not need to set up, such as anti-dropping device. The following is my response to a different mine geology, coal and so on, comprehensive calculation analysis, based on security, economic and other principles of these two kinds of lifting equipment selection system design. The design of the full implementation
