A Trial Application of Chemical to Suppress Mine-Environmental Dust-Techno Economic Evaluation

摘要

Dust is an undesirable by product of mining operations. Coal dust larger than 74 microns in size may cause explosion whereas finer than 5 micron causes pneumoconiosis. The problems I has been there since the very beginning of mining operations but the introduction of mechanised mining systems have aggravated the menace. In opencast mines a considerable amount of particulate matter is released to the mine atmosphere. While the dust generated by drilling can be contained locally, the one generated and located along the haulroads create menace peculiar to the vehicular movement or the direction and intensity of wind. Cloud of dust along the haulroads, particularly during dry months, is a typical sight. Continuous and increased frequency of traffic may result in the presence of dust clouds an everlasting affair.
