我队勘探的岚县矿区,矿层坚硬而厚,漏水严重,绝大部分钻孔都是漏着用清水钻进,钻进技术规范很不好找,特别是调节水量问题。大家知道,在钻粒钻进中水量调节得合适与否,对提高进尺和保持均衡的小时效率是有着密切的关系的,这已是每个钻探 In the mining area of ​​the Qixian County where our team is exploring, the seam is hard and thick, and the water leakage is serious. Most of the boreholes are leaked with clean water. The technical specifications for drilling are very difficult to find, especially the problem of adjusting the water volume. As we all know, whether or not the amount of water in the drilling of the drilling rigs is adjusted properly is closely related to the improvement of the footage and the maintenance of a balanced hourly efficiency. This is already every drilling.
