多绳摩擦式提升机广泛用于煤炭、有色金属、黑色金属、非金属、化工等，它是矿井提升系统重要设备。当主井提升机选型确定后，如何提高产能，优化系统参数，是工程技术人员研究的重要课题。通过对某铜矿主井提升机（JKM-4×渍1.6m）系统优化设计，减轻了矿车重量、提高了提升钢丝绳公称抗拉强度、验算了电动机功率和钢丝绳安全系数，进行改造，提高了生产能力，增加了企业的经济效益。%The multiple-rope friction mine hoist is widely applied in coal, nonferrous metals, nonmetal, chemical engineering etc. It is important device of mine hoisting systems. It is a major topic for engineering and technical staff when the main mine hoist was determined that how to improve productivity and optimize parameter of hoist systems. Through optimization design for a copper mine hoist, the tramcar weight was lighted, the nominal tensile strength of the hoist rope was enhanced, and the power of motor and security coefficient of hoist rope were checked. The production capacity was improved and the economic benefit was increased.
