Improvement strategies for mine dewatering process

A Coal Mine in Australia has experienced inefficiencies and reliability problems with the current dewatering process. This study investigated and discussed the causes for the inefficiency. The optimum conditions relating to functionality, as well as financial and environmental sustainability are discussed. Mapping of water flow is done to identify hazardous areas within the mine. Dewatering process modelling and calculation, and methods of water quality improvement are presented and discussed. Strategies for efficient dewatering system is developed and recommended for the mine authority.
