在目前党号召勤儉建國勤儉办企業的时候,地質人員决定鑽探任务都考慮以最少数的鑽孔、最小的進尺收集更多的地質資料來解决坝址工程地質問題。一个孔假若岩心獲取率很低,資料錯誤很多又殘缺不全,那么参考价值就不大,說明不了什么問題,浪費了很長时間和投資,并且影响工程進度。故鑽探人員在工作中应与地質人員密切配合,以取得指導与帮助,力求所談資料能正确反映一切地下地質情况。茲就鑽探的布置开孔、鑽進、水文地質三个方 At a time when the party calls for thrifty building a thrifty enterprise, geologists decide that the drilling task should be considered to collect more geological data with the minimum number of boreholes and the smallest footage to solve the engineering geological problems at the dam site. A hole if the core acquisition rate is very low, a lot of data errors and incomplete, then the reference value is not large, that can not be any problem, a waste of a long time and investment, and affect the progress of the project. Therefore, the drilling personnel should work closely with the geologic staff in order to obtain guidance and help so that the materials discussed can correctly reflect all underground geological conditions. Here drilling arrangement of openings, drilling, hydrogeology three parties
