Abstract: 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 production,the conventional method usually is adopted to carry out theoretical calculations,but its accuracy is low.By means of industrial 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 capacity accounting and other problems.To resolve the above problems,the physical simulation platform for hoisting system of underground 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.
