鑛柱回采是一項繁重而在技术上又复杂的采掘作業。長期拖延矿柱回釆期限就会导致矿柱变形,威胁作業場所的安全,并大大地增加了巷道維持費用。因此及时按比例的在鑛房和矿柱中采鑛就成为企業保証正常安全生产的重要措施。为确保这一措施的实現,則必須合理的选擇和采用开采强度大而又安全的鑛柱回采方法。近几年来某鑛山,在苏联專家的直接指导和鑛山研究所工作組的协助下,对加速鑛柱回采以扭转开采順序問題,进行了一系列的努力研究和革新。 Pillar mining is a burdensome and technically complex mining operation. Prolonged protracted pillars back to preclude the lead time will lead to pillar deformation, threatening the safety of workplaces, and greatly increased the cost of roadway maintenance. Therefore, timely and proportionate mining in mines and pillars has become an important measure for enterprises to ensure normal and safe production. In order to ensure the realization of this measure, it is necessary to select and adopt the mining method of pillar mining with high strength and safety. In recent years a number of mines have been studied and innovated with the help of the direct guidance of Soviet experts and the working group of the Institute of Mines to speed up the recovery of ore pillars in order to reverse the order of mining.
