摘要
针对某金矿急倾斜薄矿脉,借助ANSYS和ABAQUS数值模拟软件,分别模拟了采用双侧联络道和单侧联络道回采矿石时,采场及围岩应力演化过程。模拟过程应力演化的结果表明:用双侧联络道采矿方法回采矿体,比单侧联络道开采更有利于矿山的损失贫化管理和安全管理。
Aimed at steep-thin vein of a gold mine, stress evolutionary processes of stope and sur- rounding rock were simulated by ANSYS and ABAQUS numerical simulation software when bilateral con- tact tunnel and unilateral contact tunnel to stope ore was used separately. Stress evolution result indicates that using bilateral contact road mining method is more beneficial to dilution, loss and safety management of mine than unilateral contact road.
