Abstract:

On the situation of the country’s rapid economic development,in order to adapt to new developments,many old mines need to keep expanding production capacity,while mine hoisting system is the main factors restricting the expansion of production capacity,coupled with long duration and slow effective of construction the new shaft hoisting system,making it difficult to continue,so we carry out technological innovation on the basis of old lift system,it is the shortcut of rapid development.Taking the lift system transformation of west mining area in Jiaojia gold mine of Shandong Gold Group as an example,we describe a method of rapid increase lift capacity,we transform the single-layer cage system into a double cage,including the selection of the cage and the wire rope and transformation of the strength of lift machine.Finally,we achieve good effect of saving energy,the enhance capacity increases nearly、bled.

Key words: Lift system, Transformation, Program design, Double cage
