Coarse dust around mining areas: a study of available dust collectors and their efficiency
Student paper otherStudent thesis
The current research was focused on the dust particles ranging from 10ìm to 2mm around mining area. This fraction of coarse mining dust is considered to be non-respirable, therefore catch less attention than respirable dust. The necessity of the research were analyzed by doing a literature study, and dust collectors that could be available for the future study on coarse mining dust were listed in the report. Laboratory work was carried out to analyze the dust samples collected from residential area close to LKAB mining site. At last, a future plan was figured out to give guidance for the continuous further study on current subject. The conclusion of the literature study showed that there is an urgent need to start the study on coarse dust around mining area, and the inverted frisbee and marble dust collector are two promising ones with improved catching efficiencies on dust collection therefore should be further tested both experimentally and practically. The tested results from laboratory work showed the dust contains metals indicating the dust origin from mining site, and the particles from mining site are coarser than natural soil. The two significant dust sources in this mining site are the dam and the huge open pit. Lots of actions could be done for dust control purposes. And to improve the dust monitoring, a wind anemometer and a horizontal gauge should be added to the station where dust collected, and a more efficient dust collector of inverted frisbee is suggested to replace NILU collector. The future plan was compiled in three aspects including dust measurement, dust origin as well as dust generation, spreading and settling. The suggestions in future plan offer a general direction in which we should mainly endeavor to.
