Application of Casing Running Technology in Directional Water Exploration and Discharge Holes in Underground Coal Mine

Casing running is a very important work in the construction of directional water drilling in underground coal mine, and it is the key to ensure the safety and smooth implementation of subsequent directional drilling and water discharge. Combine engineering examples, analysis of the technical principle of casing running, corresponding technical measures are proposed to form a complete set of effective casing running technology and compound drilling tools, which provides reference for similar project construction in the future.
