摘要:

摘 要:根据岩石物理力学性质,水文地质条件综合分析,采用预先疏干工程,预先降低含水层水位及水压,避免采掘场内涌水造成采掘作业停滞;有效降低含水层对边坡稳定性的影响及含水层水压。

Abstract:

Abstract According to rock physical and mechanical properties and hydro geological conditions, adopting pre-drainage project, the project lowers water level and water pressure of aquifer in advance, and avoids mining operation stagnation caused by water inflow in stope, which effectively reduces the effect of aquifer on slope stability and Water pressure of aquifer.
