Criteria analysis in the selection method of mud pumping in coal mining project

The process of discharging water from the pit is one of the stages prior to the continued excavation of coal deposits. Due to the increase of coal price, several areas that were not economically valuable became visible to re-mined. In some mine ponds that are considered economically viable, are necessary to pump the mud before carried out the water before further digging. This requirement needs decision-making for the determination of sludge pumping methods. A large number of criterion variables for selecting the best mud pumping method drives this study. The distance of three mine ponds under the company is quite far each other. Some steps were executed to have the best method to cater to the problem. The results indicate that there are six criteria that suitable to be considered in selecting a method for mud pumping. Those are the productivity of pump, man power, mobilization, supporting facilities, flexibilities, and operational cost.
