在磷矿钻探施工中,所遇的岩矿层构造比较复杂,如非均质、软硬互层,节理发育、多裂隙、硬、脆、碎或松散、粉状,尤其是含矿品位越高,矿化越好的岩矿层,脆性就越大。这些地质因素给岩矿芯的采取和钻孔弯曲的防治造成很大困难。所以,加强磷矿钻探取芯和防治斜技术的研究,探讨其规律,总结成败的经验教训有其重要的意义。
In the process of phosphate rock drilling, the structure of rock and mine encountered is quite complex, such as heterogeneous, hard and soft interbed, joint development, multiple cracks, hard, brittle, broken or loose, powder, especially the ore grade , The better the rock mineralization, the greater the brittleness. These geological factors have caused great difficulties in the rock core and drilling and bending prevention and treatment. Therefore, it is of great significance to strengthen the study of coring and prevention and control of phosphate rock drilling technology, explore its law and summarize the experiences and lessons of its success or failure.
