Integrated DTH drilling rigs integrate drilling host, air compressor, power system and walking chassis into one whole unit without separate supporting equipment, widely used in open-pit mines, quarries and road engineering. They are classified by chassis, power form and drilling capacity. In mobility classification, crawler integrated DTH rigs take the dominant place. Equipped with rubber or steel tracks, they travel freely on mud, steep slopes and uneven mine ground. Wheel-integrated models suit flat construction zones for quick short-distance transfer. By power source, diesel integrated rigs work independently in remote sites without power grids, being the mainstream type. Investing in an electric integrated DTH drilling rig allows operators to run with low noise and zero emissions, making it highly suitable for urban slope reinforcement and indoor projects. Based on drilling depth, light integrated rigs drill within 35m for small blasting and anchoring holes. Medium ones cover 35–80m for general quarry mining. Heavy integrated DTH drilling rigs reach over 80m for large open-pit exploitation. Featuring automatic feeding and centralized control panels, they deliver high efficiency and simple operation compared with separated split rigs.
