Abstract: Environmental Protection of Mining Development Limited Company)〖SX）〗Abstract        Through analyzing the status of tailings particle size, the dam height, the length of dry bank, and the tailings discharge methods and the relevant scientific experiments, it is shown that dust is generated from tailings mainly due to fine size of tailings, high speed wind at dam, too long dry bank, and worse management on multi-pipe discharging. For tailings dust treatment, the paper takes the comprehensive dust control measures, among which controlling the length of dry bank and strengthening the management of multi-pipe discharging belong to the measures in production. At the key sites, tailings dust can be controlled by dust covering agent, water spray at dry bank, greening of dry bank and other measures based on the chemical composition of tailing, water and power supply situation at the reservoir and the situation of sub-reservoir.
