Stability Analysis of Steel Pipe with Large Diameter under Radial Pressure during Deep Shaft Construction

Abstract:

With the increase in depth of coal mining, coal mines constructed are constructing some industrial building of new type in order to improving word condition and increasing utilization of energy. E.g. deep vertical Shaft Carries water chilled to decreasing hyperthermia harm of coal face, the methane is used by steel pipe drainage from deep coal area. Steel pipe’s instability under radial pressure lead to failure during deep shaft construction, calculative method applied isn’t perfect. Critical force of stability is analyzed by theoretical analysis、experimental research and numerical simulation, conclusions can be used for designing as a reference.
