在回采戈罗布拉哥达特矿床的保安矿柱时,在采矿影响区内有综合烧结厂、选矿厂和磁选厂、南矿工业广场、机车库等工程设施。保安矿柱的埋藏深度为320～560米(图1),厚10～60米,倾角20°～30°,沿走向长100米,在该矿床和南区之间有一无矿带,沿走向长700～800米。围岩为玄武玢岩、凝灰岩和捕虏凝灰玢岩,岩性坚硬稳固。
During the recovery of the security pillars of the Gorobbuda Dute deposit, there are integrated sintering plants, concentrator and magnetic separation plants, South Mining Industrial Square, garage and other engineering facilities in the mining area of influence. The security pillar is buried at a depth of 320-560 meters (Figure 1), with a thickness of 10-60 meters, an inclination of 20-30 degrees and a length of 100 meters along the strike. There is a mineralized zone between the deposit and the southern area along the strike 700 to 800 meters long. Surrounding rocks are basaltic rocks, tuffs and captive tuff rocks, which are hard and firm.
