Investigation of Dust Generation & the Effectiveness of Suppression Techniques Used on Longwall BSL and Crushers.

Andrew Rutherford Pty Ltd – November 2003

Proposal Summary:
The Joint Coal Board, now Coal Services, has been entrusted with the Underground Coal Health for many years, and this includes the monitoring of environmental factors, especially dust via the Standing Dust Committee.

Through this committee, longwall exposure is measured on a regular minimum six monthly basis and advice and assistance offered to the mines on dust control and mitigation.

One area of high dust make is the BSL and Crusher, where the resultant dust can severely contaminate intake ventilation and therefore expose greater numbers of operators to high dust exposures.
