Mine dewatering processs : improvement strategies on existing system

Water, an essential fluid for the mining progression, eventually finds its way to the bottom of the mine due to the effects of gravity. Expulsion of water is not simple and in fact is complicated due to a number of complex issues such as water build-up in the underground mine. By mapping water build up through out the mine identifies where problem areas are allowing for mechanical or geological means of diverting stagnant water to sumps. 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 environmental sustainability are discussed. Mapping of water flow is done in order to identify hazardous areas. Dewatering process model and its calculation, and methods of water quality improvement are elaborated. Strategies and the roles of maintenance leader for efficient dewatering system is developed, discussed and recommended for the mine authority.
