鑽探是地质勘探工作的一种手段。一个鑽孔效果的好坏,不只是决定于鑽探施工的质量,而且也决定于鑽孔设计的正确性。过去我队某些鑽孔的岩矿心采取率虽满足了地质要求,但鑽孔的理想设计与实际施工結果却相差很大。有的在同一剖面上,第一排鑽孔与第二排鑽孔几乎相交起来,这样就不符合整个勘探工程的佈置要求,严重影响了计算矿量。现将我队在这一方面的几点教训和经验写出,供同志们研究参考。
Drilling is a means of geological exploration. The quality of a borehole depends not only on the quality of the drilling application, but also on the correctness of the borehole design. In the past, some of the rock drilling center of our team to take the rate although to meet the geological requirements, but the ideal design of the borehole and the actual construction results are quite different. In some cases, the first row of drilling holes and the second row of drilling holes almost intersect on the same section, which would not meet the layout requirements of the entire exploration project and seriously affected the calculation of ore amount. Now my team in this area a few lessons and experiences written for comrades to study and reference.
