Abstract: On the basis of analyzing the failure of buffer roller of belt conveyor, this paper discussed the improved design of
buffer roller, and carried out strength check on the load-bearing performance of the improved buffer roller. The results showed
that the load-bearing performance of buffer roller was significantly improved after the improved design, which could better meet
the needs of production transportation in underground mines.

Key words: mine; belt conveyor; buffer roller; failure; improved design
