150m Deep Underground Hard Rock Drilling Equipment Customized Dia

XY-1A hard rock drilling equipment is a widely used portable drill suitable for drilling water wells, geological survey, geological core drilling, small grouting holes, and blasting holes for railway, water conservancy, bridges, dam foundation, and other construction projects. According to different strata, it drills by choosing diamond, composite films, and alloy bits.

This hard rock drilling equipment is suitable for geological survey, geological core drilling, small grouting holes, and blasting holes for railway, water conservancy, bridges, dam foundation, and other construction projects. It can drill through different strata by choosing appropriate bits including diamond, composite films, and alloy.

The drilling rig is mainly used for geological general investigation and exploration, road and tall building foundation exploration, various holes in concrete structures, river levees, subgrade grouting holes, drilling and direct grouting, civil wells, and earth temperature central air-conditioner systems.

The drill bit plays a crucial role in water well drilling operations. Bit quality directly affects drilling efficiency and quality. Proper selection and usage are essential for optimal production and operation.

• After completing the drilling structure, replace the central drilling tool promptly. Clean the hole bottom and blow away residue. Stop drill bit rotation before slowly lifting the drilling tool with appropriate force.
• Monitor casing follow-up during drilling, maintain awareness of hole conditions, and keep the hole clean when necessary. Avoid forcing the drill bit during extraction.
• When excess rock slag accumulates at the hole bottom, potentially jamming the eccentric bit, apply air pressure to clean the hole, activate the DTH hammer briefly, then lift the central drilling tool again.
