Abstract: According to the complicated hydrological conditions in western Inner Mongolia mining area,based on the ground freezing method construction,with the 0 ptimization of the mechanized matched combined operation method in the mine shaft,three sets of the large mime shaft hoisting equipments,new double linked FJD-6G mode 12 boom umbrella drill and the YGZ-70 mode rock drills were applied to the simultaneous rock drilling matched construction.The shaft with a max net diameter of 10.5 m was completed.The shaft with an excavated diameter of 15.5 m was constructed.The average month shaft completed over 100 m in depth was realized in that ar ea and the max month shaft completed was 120 m.The mechanized matched equipment capacity was fully played.On the premise of the project safety and quality ensur ed,the construction speed was speeded up and the cost was efficiently reduced.
