矿山提升系统是矿山开采中的重要系统之一，矿山提升系统、通风性能等的优化有利于矿山生产。当今对已投产矿山的提升系统进行优化时，借助常规的方法进行理论计算，准确性差；借助工业试验，需要矿山停产，进行系统变更，而变更系统要投入大量的人力、物力与财力，成本太高；而对未采矿山提升系统的模拟大多数只停留在计算机辅助模拟和静态模拟阶段，无法解决教学演示、提升能力与摩擦风阻的核算等问题。为此，对照真实提升系统，按1∶100的比例，构建一种地下非煤矿山提升系统物理仿真平台，通过可编程控制系统实现罐笼的提升与运输；在此平台的基础上，通过更替可变换直径的井筒以及可调节体积的罐笼，依据具体事例设计参数，对矿山进行提升能力和井筒摩擦风阻的核算，为矿山优化提供参考。实例分析证明，该平台可以降低地下非煤矿山提升系统运营成本，减少安全隐患。
礦山提升繫統是礦山開採中的重要繫統之一，礦山提升繫統、通風性能等的優化有利于礦山生產。噹今對已投產礦山的提升繫統進行優化時，藉助常規的方法進行理論計算，準確性差；藉助工業試驗，需要礦山停產，進行繫統變更，而變更繫統要投入大量的人力、物力與財力，成本太高；而對未採礦山提升繫統的模擬大多數隻停留在計算機輔助模擬和靜態模擬階段，無法解決教學縯示、提升能力與摩抆風阻的覈算等問題。為此，對照真實提升繫統，按1∶100的比例，構建一種地下非煤礦山提升繫統物理倣真平檯，通過可編程控製繫統實現罐籠的提升與運輸；在此平檯的基礎上，通過更替可變換直徑的井筒以及可調節體積的罐籠，依據具體事例設計參數，對礦山進行提升能力和井筒摩抆風阻的覈算，為礦山優化提供參攷。實例分析證明，該平檯可以降低地下非煤礦山提升繫統運營成本，減少安全隱患。

Hoisting system is one of the essential systems in the process of mine production and design,and the optimized hoisting system and ventilation favor the production. Now when optimizing the mine hoisting system that has been put into pro-duction,the conventional method usually is adopted to carry out theoretical calculations,but its accuracy is low. By means of in-dustrial tests,the mine should be shutdown for changing system,which lead to a great waste of manpower,material and financial resources,so that the cost is high. For the mine that does not put into production,most simulations for hoisting system only stay in computer-aided simulation and static simulation stage. These are unable to resolve the teaching demonstration,hoisting ca-pacity accounting and other problems. To resolve the above problems,the physical simulation platform for hoisting system of un-derground non-coal mine is constructed in the ratio of 1 to 100 which is relative to the real hoisting system,and cage lifting and transporting can be achieved by the programmable control system. On the basis of this platform,lifting capacity and wellbore friction drag will be accounted,to provide reference for mine design,by replacing wellbores with different diameters and the cage with adjustable volumes according to the specific examples of design parameters. The practice proved that this platform can reduce the costs of hoisting system in non-coal mine,and reduce security risks.
