CHINA MINE ENGINEERING

With the continuous increase of mining depth, high water pressure brings great challenge to mine production, high water pressure waterproofing gate will be more and more popular in engineering, and underground waterproofing gate is an important safety facility to prevent water penetration accident, more and more enterprises pay attention to and apply in production. Taking the chamber design of 7.5MPa waterproofing gate as an example, the author discusses the problems of structural design and the selection of discharge mode, and accumulates experience for the following similar projects.
