Abstract: In the quest for economical mining operations, much emphasis should be placed on controlling flood in order to achieve reserve optimization, adequate crusher output, equipment mobility and effectiveness. This study therefore, focuses on flood control in a mine environment taking particular reference in Shagamu Limestone Quarry, Sagamu, Nigeria. The study sheds, more light into the geology of the deposit of the study area, the dewatering and drainage process, operating characteristics, performance and efficiency of pumps were discussed. The Shagamu limestone quarry daily pump record for four weeks were taken and subjected to statistical analysis. The result gotten indicated that their method of flood control is effective. However, it was noted that huge sum of money were expended on pump repairs especially, during rainy season, which is due to epileptic power supply in Nigeria. Additional recommendations were proffered to further enhance the effective and efficient control of flood on the quarry floor.
