地质勘探工作中的山地工程,大都不是永久性建设。探井、巷道的支柱是为了掘进工作中的安全,一般使用时间不长,特别当勘探后证明没有工业价值时,支柱就要拆除。因此我们根据矿井的建设情况,在深井掘进中采用了临时钢筋掛钩吊框支柱法。这种支柱方法的优点是:结构结实,架设迅速,拆卸方便。在我们地质勘探工作中有相当的实用价值。
Most of the mountain projects in geological exploration work are not permanent construction. The pillars of exploratory wells and roadways are used for safety in the excavation work. Generally, they are not used for a long time. When the exploration proves that there is no industrial value, the pillars must be dismantled. Therefore, according to the construction of the mine, we adopted the method of temporary steel hook hanging frame pillars in the deep shaft excavation. The advantages of this pillar method are: strong structure, rapid erection, and easy disassembly. It has considerable practical value in our geological exploration work.
