The Equipment Organization of the Mineral Exploration Office of the Ministry of Natural Resources has conducted research on mineral exploration equipment and comparative analysis of mineral exploration technology and equipment at home and abroad. The results indicate that after decades of accumulation， although progress has been made in the development of exploration technology and equipment in China， there are still some shortcomings and challenges. Overall， the current geological exploration team in China is equipped with outdated equipments， limited green advanced equipments， and mainly imported advanced instruments and equipment. The domestic research and development support capacity is insufficient， the level of equipment industrialization is not high， and the safety guarantee conditions for field life are poor. It is urgent to strengthen the construction of mineral exploration equipments， support the comprehensive promotion of green exploration， and meet the new demand for mineral exploration equipment in the new round of breakthrough strategic actions. The China Geological Survey Bureau of the Ministry of Natural Resources has taken the lead in accelerating the construction of a modern field condition guarantee system， and has successively formulated institutional documents such as the Guiding Opinions on Strengthening the Use of Geological Survey Field Comprehensive Support Bases. The main task is to promote green exploration and shorten the gap with advanced equipment levels abroad. To meet the requirements of the new round of strategic mineral exploration and the refinement of national major engineering surveys， the HRD800F horizontal core drill was developed. The power head is a key component of a core drilling rig. This article elaborates on the design scheme， design process， and testing process of the power head for this type of core drill， and summarizes the performance characteristics of the power head.
