Mine drainage system is the core supporting project for safe production of open-pit mines and underground mines, which is directly related to the safety of underground operation, the stability of surrounding rock of roadway and the overall production continuity. Problems such as mine water gushing, water seepage in rainy season, and groundwater backward flow can easily lead to roadway water accumulation, equipment soaking, slope instability and even water seepage accidents, which is the top priority of mine safety management and control. A set of scientific and perfect mine drainage system not only needs reasonable pump unit...

Many mine pipeline projects have some problems, such as insufficient water pressure, pipe explosion and leakage, rapid aging of pipe network, etc., which are not essentially pipe quality problems, but caused by mismatched design parameters in the early stage, chaotic application of standards, and inadequate site construction details. Especially in South Africa mining area, the terrain difference is large, the temperature difference between day and night is obvious, and the field conditions are harsh, so the requirements for the design specification, pressure bearing grade and laying standard of South Africa mining pipeline are far more stringent...

Practitioners who have had mine site experience know that the replacement of tailings pipeline is one of the most time-consuming, production-affecting and costly tasks in mine operation and maintenance. In order to control the budget, many project teams choose ordinary steel pipes or ordinary HDPE pipes at the beginning. After just a few years of operation, problems such as pipe wall wear, leakage and pipe explosion will frequently occur, which will directly lead to unplanned downtime and cause considerable economic losses. This problem is particularly prominent in lithium mine and rare earth mine projects. The tailings...
