Based on the present situation of the development of mineral resources in China, by the comparison analysis on the existing core drills both in China and abroad, YDX-1 portable core drill was developed with characteristics of high-efficiency, lightweight and portable, modular and fully hydraulic top driving. The related data in drill operation and drilling process are collected, analyzed and processed by electro-hydraulic control, virtual instrument and internet network technologies; the drill rig fault diagnosis and treatment, the recognition of operating conditions and automatic processing of typical conditions, drilling parameters optimization, remote data transmission and monitoring are carried out to realize the automation control of drilling process. The practice proves that YDX-1 portable core drill has the characteristics of excellent performance with reasonable design layout, wide application, high reliability, high mechanization degree, good overall quality and strong adaptability of drilling technology; it is a new generation of drilling machine for exploration in mountainous and inconvenient traffic areas.
