Mine Water Pouring, Causes and Prevention of

Mine water pouring is a phenomenon in which the underground mining process destroys aquifers, water barriers, and hydraulic faults, causing rock movement and ground collapse, resulting in groundwater and surface water gushing out into underground shafts, chambers, and mining sites. It is also known as mine water gushing. Mine water pouring deteriorates the underground environment and brings certain difficulties to the construction, digging, mining, and management of mechanical and electrical equipment.

Downhole water inrush mainly comes from atmospheric precipitation, surface water, groundwater, mining wastewater, old goaf water, filling water seepage, etc. The amount of downhole water inrush is an important indicator for evaluating the technical, economic, and safety feasibility of mine construction. Studying the size and characteristics of water inrush is the main basis for rationally designing mine construction and production plans, designing mine waterproof and drainage...
