| According to the geological conditions of the working face and the other case ofequipment supporting, we selected models for filling hydraulic support and done somesimplified mechanical analysis and structural analysis. With the use of computer-aidedanalysis, we studied the finite element analysis for the overall strength of the stent. Focusedon identifying the location of the double top beam hinge pin, the pin were here for load test ofthe mechanical analysis and computer simulation. In the design process of the double tampingmechanism, we mainly studied the stability of the stent in the no-load and full load. Under thepremise of exhibit fabric system defects, we select models for backfill mining conveyor. Theindustrial test were implemented in some working faces, data that this filling mining for themining basically showed no impact to surface buildings and facilities. |
