The Evaluation of The Safety of Underground Catchwater Engineering under the High Water Pressure in Wennan Mine

摘要

In this paper, by using TFINE elasto-plastic finite element program with 3-D model, the change of stress-strain of the underground catchwater engineering under high water pressure and some sorts of hydraulic conditions is studied, the softening action of pressure water is also analyzed. Moreover, the international advanced analytic method of point safety degree is adopted and the stability and safety of underground catchwater engineering are analyzed and evaluated. All of these works will provide new methods for control of mine gob water.
