Abstract:

Based on remodeling of raw coal main transport system, the colliery constructs a semi-continuous waste rock discharging system. Waste rock will be transferred to temporary storage roadway through the belt conveyor and scraper conveyor, and will be discharged using this system while coal is not in use. The application of this system will significantly improve the waste rock discharging transport capacity of this colliery, greatly reduced potential risk, as well as saving the coal mine production and operating cost.

Key words: the main transport system, semi-continuous waste rock discharging system, plow discharger, Slip coal mouth remodeling
