VCR法免除了人员在顶板下作业,大大提高了采矿的安全性。但是,它依然存在着地压方面的问题,例如:凿岩峒室、采准巷道的稳定性,充填体的工作性态等。针对上述问题,本文论述了在凡口矿的现场研究和室内模拟结果。它为该法的设计和施工管理提供了岩石力学的依据。 The VCR method eliminates the need for personnel to work under the roof and greatly increases the safety of mining. However, there are still some problems with the ground pressure, such as the rock drilling chamber, the stability of the quasi-entry roadway, the working behavior of the filling body, and so on. In response to the above problems, this article discusses the site research and indoor simulation results at the Fankou mine. It provided the basis of rock mechanics for the design and construction management of the law.
