Visibility problem under control

摘要

WHILE ENVIRONMENTAL, HEALTH and safety issues are the primary reasons for worry, dust can also have a major impact as the result of increased maintenance and clean-up costs. It is also an indication that mined ore is being lost as it is being transported from the pit to the crushing circuit. Although water can minimise certain dust problems, the benefits are short term. Furthermore, the addition of water can cause surfaces to become slippery. According to General Electric, it has been proven that regular watering and the application of chemical suppressants in conjunction with optimal aggregate surfaces is the only effective option for controlling fugitive dust emissions on haulage routes.
