CMR1000 Multi-Purpose Drilling Rig

Depth capacity: 2000m(BQ) Rod Diameter: BQ to PQ Drilling angle: 45~90 degree CE Certification

CMR1000 is designed for multi-purpose drilling, and is a high capacity, heavy duty multi purpose drill rig which is highly effective in diamond coring, reverse circulation and rotary drilling techniques.

 Air hammer drilling techniques   Axial pressure works against the up ward force when the air hammer pushes down the pistons, ensuring the drilling force efficiently passing through the pipe to the bit. When using air hammer drilling, the speed is 15-30 rpm.

 The features below defines the performance of RC drilling,

1. high drilling efficiency

2. Adopted to complicated ground stratum

3. Quality hole formation

4. Simple drilling technique

5. lower cost

6. Less contaminated samples

Combination of core drilling and RC drilling

  The drilling depth of most the present RC drill is up to 400 meters due to using heavy double-wall drilling pipes, CMR-1000 is perfectly designed by combination of core drilling and RC drilling, RC drilling for shallow drilling and quality control, and core drilling for deep drilling and long term reserve estimation.
