| Abstract: | Through engineering practice, the converse-well drilling rig construction technology was applied to the inclined shaft excavation with degree of 48 ° and 60 °, it was shown that inclined wells was proved the converse construction process can be replacing the traditional manual converse missile or climbing well for inclined shaft construction technology. It is a highly efficient and safety construction method. At the same time, converse well drilling rig construction was particularly prevalent for the inclined shaft with the degree of 60 °-90 °, the converse well drilling rig construction technology of shaft excavation with the inclined degree of 48 ° successfully, shows that it may expand the application the converse drilling wells to the scope of inclined degree of 48 °-90 °. |
