DTH drilling rigs use hammer impact at the bit bottom for fast rock breaking, widely applied in quarrying, mining, blasting and foundation construction, sorted by mobility, power and working scenarios. By chassis type: Portable split DTH rigs are lightweight for small mountain blasting holes. Skid-mounted models are fixed on flat mine sites with stable performance. Mini crawler DTH rigs feature flexible off-road travel, fit slopes and muddy open pits. Truck-mounted rigs enable quick transfers for large-scale road and quarry projects. Power falls into two mainstream categories. Pneumatic DTH rigs rely on external air compressors, low cost and durable for hard rock drilling. Hydraulic DTH rigs integrate independent power packs, delivering higher efficiency and easier operation without bulky air pipelines. By application depth and hole size: Light units drill shallow blast holes within 30 meters. Medium rigs handle 30–80m holes for open-pit mineral mining. Heavy-duty DTH rigs reach over 80 meters for large quarry and water well drilling. Explosion-proof pneumatic variants are specially customized for underground mine tunneling and gas-containing working faces. Partnering with a professional dth drilling rig manufacturer ensures strict adherence to these customized standards. Whether you need reliable machinery for harsh mining environments or high-efficiency components, selecting a trusted dth drilling rig supplier guarantees complete technical support and reliable field performance for every project.
