用边界元法研究灵湖金矿回采过程中岩体的稳定性,为回采顺序、采场结构、支护手段、矿柱受力状态等问题的解决,提供了理论依据。生产实践证明了该研究成果的正确性。灵湖金矿采用“沿倾斜后退式回采锚杆护顶房柱法”方案,解决了难采矿体的开采问题,取得了显著的经济效益和社会效益。
The boundary element method is used to study the stability of rock mass during the recovery process of Linghu gold deposit, which provides a theoretical basis for solving the problems of recovery sequence, stope structure, supporting measures and stress state of pillar. Production practice proves the correctness of the research results. Linghu Gold Mine adopted the “along the inclined back to the mining roof bollards” program to solve the difficult mining problems, achieved significant economic and social benefits.
