Selection and optimization of mine pumping systems

Abstract

The paper describes various factors which affect the design of a pumping system for a mining layout. Variation of the make and quality of mine water with respect to mine layout and developments are important factors to be considered in the design of a pumping system. The main pumping duties which can be assigned to a mine dewatering system are specified in terms of delivery rate, total head and the quality of mine water. The physical effects of undissolved solids on the wear and tear of the pump are outlined together with the possible solutions. Various inter-related design factors considered in the paper are standage capacity, water make, load factor, cost of minimizing friction losses, centralized pumping versus individual pumps delivering directly to the surface.

Types of pump available together with their operational characteristics have been discussed in relation to selection and optimization of mine pumping systems. Typical case histories are described that indicate the necessity for advanced planning in solving specific pumping problems.
