Optimising the operation of drainage systems to improve the safety of deep mine sumps

Abstract This paper discusses the problem of the accumulation of solid materials and water in deep mine sumps, which negatively affects the safety and efficiency of sumps operation. The proposed solution is the implementation of two-stage pump-hydroelevator systems. The research is based on theoretical modeling, empirical analysis, and experimental testing using methods of hydrodynamic modeling and energy consumption calculations. The results showed that automating the processes of cleaning and pumping water reduces the number of accidents by 50-80%, shortens the time personnel spends in hazardous zones by 70-90%, and allows for operation at depths of up to 200 meters. The implementation of the systems also increases the lifespan of pumps by 1.5–2 times and reduces maintenance costs. Automated systems enhance the safety and efficiency of mine operations, ensuring the stable operation of sumps.
