复杂、富水地质条件下硐室与巷道支护技术研究

Tunnel and Chamber Supporting Technology Research under the Complex and Rich Water Geological Conditions

为解决白象山铁矿复杂、富水地质条件下硐室和巷道支护问题,我们开展了岩石物理力学性质试验、综合物探地质超前预报工作,并依据其揭示的工程与水文地质条件对硐室和巷道围岩进行了分级,研究制定并实施了硐室和巷道支护方案。

In order to solve the problems of chamber and tunnel support in the complex and water rich geological conditions of Baixiangshan iron mine,we have carried out the rock physical and mechanical properties test and comprehensive geophysical geological prediction,and classified the chamber cavern and tunnel roadway surrounding rock according to the engineering and hydrogeological conditions revealed by it. We study and formulate the supporting scheme for chamber and tunnel. The result of the support scheme was analyzed by monitoring means and proved that the support scheme was safe and reliable.
