Abstract: In response to the technical bottlenecks of insufficient process adaptability and low automation level of traditional geological drilling rigs, this paper develops a vehicle mounted multi process automated drilling rig. This device integrates non circulating sampling, air down the hole hammer, and flushing fluid coring drilling processes, and through innovative research and development of multi process power heads, drill pipe automation processing systems, and digital control technology, achieves collaborative operations of rapid sampling of cover layers (efficient air drilling supports real-time geochemical analysis to delineate anomalies) and precise coring of rock and mineral layers (flushing fluid drilling provides key physical objects for resource reserve assessment). In the demonstration applications of typical coverage areas such as Zhangjiakou in Hebei and Chifeng in Inner Mongolia, the key performance indicators of drilling rigs (drilling depth capability, reliability of drill pipe processing system, accuracy of drilling parameter collection, etc.) have all met the design requirements, providing efficient technical equipment support for the rapid breakthrough of strategic mineral exploration in coverage areas.
