一目的和现状辽宁某石棉矿床深部开采机会性研究的目的,是确定该矿-450米水平以下矿床开采的最佳临界深度,为深部矿床勘探和开采的可行性提供依据。该矿原已进行了第一、二期建设工程,现有双流程选厂一座,设计年生产能力石棉一万吨,年处理矿石26万吨。矿井采用中央并列竖井、两翼风井、刘角式开拓系统。主提升井净直径5.0米,井深-460.49米,年提升能力27.6万吨。充填副井净直径4.7米,井深-471.51米,年提升能力12.5万吨。两竖井最大提升深度均达-450米水平。
Aim and Status The purpose of the deep-seeding exploration of a certain asbestos deposit in Liaoning is to determine the optimal critical depth of ore deposit below -450 m and provide basis for the feasibility of exploration and exploitation of deep deposits. The mine has been carried out the first and second phase of the construction project, the existing dual-process plant selected a design annual production capacity of 10,000 tons of asbestos, the annual processing of 260,000 tons of ore. Mine central parallel shaft, two wings air shaft, Liu angle open system. The main hoist well has a net diameter of 5.0 meters, a well depth of -460.49 meters and an annual lifting capacity of 276,000 tons. Filling auxiliary shaft net diameter of 4.7 meters, well depth -471.51 meters, annual lifting capacity of 125,000 tons. Maximum lifting depth of both shafts up to -450 meters level.
