Core Drilling Rig

Choosing a right drilling rig is important for coring. Generally, core drilling rigs should be chosen according to design depth of drilling, design angle of drilling, rock conditions, and drilling methods etc. Here we give you some examples as follows:
Diamond core drilling requires hydraulic drilling rigs with higher speed and wider range of speed regulation. Besides, the drilling rigs should be equipped with bottom hole pressure gauge, speed and torque meter. When driven by electric motor, core drilling rigs should be fitted with voltage meter and ammeter.
When creating holes in the alluvial layer, stack layer or loose sandy land, blade bits or common carbide drill bits can be used. The mud can be used as washing fluid.
Impact bits are suitable for drilling into gravel layer. Drilling after cement injection or orifice tube embedment is also applicable.
When drilling in hard rock, you should use carbide drill to drill a hole of 300mm depth, and then use diamond-impregnated bit.
