Design of Debris Shield of Powered Support with 6.2M Large Mining Height

Abstract:

One of the difficulties of the world’s mining industry is how to ensure safe and reliable work of the powered support with large mining height more than 6m. The paper introduces the design and calculation of debris shield of the powered shield support with 6.2M large mining height. In this paper, first mechanical model of powered support with large mining height was established, the mechanical characteristics of powered support was analyzed, and overall design of powered support and general structure of debris shield could be done according to the force calculation.
