我队为使坑探工程逐步向机械化方向发展,扭转坑探浅井施工长期处于手工操作的落后状态。近年来,我们对现有坑探机械产品结合我队施工地处海拔高达2800米以上、气压低的具体条件进行了全面权衡,选择了部分不受海拔、地形、地质条件影响、且又简易轻便的设备,进行系统配套试验,经使用达到了预期
In order to make the pit-digging project gradually develop toward mechanization, our team reversed the long-term pit-exploration and shallow-well construction in a laggard state by hand. In recent years, we have carried out a comprehensive trade-off between the existing pits and mechanical products and the construction of our team located at an altitude of more than 2,800 meters above sea level. The specific conditions of low pressure are selected. Some are not affected by altitude, topography and geological conditions, Of the equipment, the system supporting test, by using to achieve the desired
