Based on LCB and PosiStop hydraulic brake system and its working principle , the PosiStop braking system is proposed on the 2 m 3 scrapers and the design calculation and analysis of its application are carried out. The actual ap- plication result shows that , using this new brake technology on 2 m 3 scrapers ,it can im- prove the safety performance of the underground scrapers and meet the needs of under- ground safety production.
