Abstract:
The new round of strategic action for mineral exploration breakthrough has put forward higher requirements for drilling technology, and the shallow drilling technology is of great important for rapid verification in shallow cover area. Moreover, the multi-technique drilling technology can provide technical supports for green and efficient drilling in complex formations. Based on this requirement, the TGQ-200RC multi-technique automatic drill is developed. The overall schedule of the drill is formulated, and the main components of the drill are designed such as the multi-techniques power head, clamping and unscrewing device, 6-DOF drill rod swinging mechanism, vehicle-mounted integrated hydraulic rod storage, electro-hydraulic control and parameter monitoring system. Furthermore, the process of multi-mechanism collaborative action during automatic adding and removing drill rods was planned. The field test shows that the TGQ-200RC drilli has high drilling efficiency, good sampling quality, and features of multi-technique capability, mobility, automation, and digitization, the average time for a single automatic adding or removing of drill rods is about 90s. With the wireless remote control, it can achieve unmanned operation in the wellhead, effectively reducing labor intensity and improving operational safety. The TGQ-200RC multi-technique automatic drill can provide solid support for building a green, efficient and economical rapid verification drilling technology system, and useful reference for promoting the automated upgrading of domestic shallow drilling equipment.
