摘要

意图Bou Azzer矿在钴开采过程中遇到了困难。为了选择岩土稳定性问题最小的最佳开采顺序,一种可能的变体是Bou Azzer东部地区540 m深度的路堑和回填采矿方法。本文提出了一种使用二维岩土工程数值模型选择充填采矿方法序列的方法,该方法考虑了矿石和围岩的形态特征、地质力学特性。调查结果。岩石充填采矿和岩石胶结充填采矿的顺序表明,高主应力(Sigma 1)在10-153MPa范围内,安全系数在0.63-1.89范围内。因此,具有胶结回填和欠胶结回填的采矿序列具有10-112MPa范围内的主应力(Sigma 1)和可接受的安全系数。独创性在本研究中,针对低质量蛇纹下盘的情况,提出了自下而上的胶结充填采矿顺序。该开采顺序旨在实现良好的钴矿生产,并为矿工提供安全的环境。实际意义。在采矿业中,选择使用2D或3D岩土数值建模的采矿方法对于确保矿山寿命中最安全、最具操作性的采矿顺序非常重要。

Geotechnical modeling of the method for mining cobalt deposits at the Bou Azzer Mine, Morocco
Purpose. The Bou Azzer Mine encounters difficulties during cobalt mining. In order to select the optimal mining sequence with the least geotechnical stability problems, one possible variant is the cut and backfill mining method used in the Bou Azzer East area at a depth of 540 m. Methods. This paper presents a methodology for selecting a sequence of the cut and backfill mining method using 2D geotechnical numerical modeling, taking into account the morphological characteristics, geomechanical properties of the ore and the surrounding rocks. Findings. The sequences of mining with rock backfill and rock-cemented backfill show that the high principal stress (Sigma 1) is in the range of 10-153 MPa, and the safety factors are in the range of 0.63-1.89. Therefore, mining sequences with cemented backfill and under cemented backfill have a principal stress (Sigma 1) in the range of 10-112 MPa and acceptable safety factors. Originality. In this study, the bottom-up mining sequence with a cemented backfill is proposed for the case of low-quality serpentine footwall. This mining sequence aims to achieve good cobalt mine production and provides a safe environment for miners. Practical implications. In the mining industry, the choice of mining method using 2D or 3D geotechnical numerical mo-deling is important to ensure the safest and most operational mining sequence in the mine lifetime.
