Gold Mine Sampling Drilling SRC531 3 3/4'' 95mm RC Drill Bits
Product Introduce: Reverse circulation hammers and bits are used in exploration and
grade control applications to obtain an accurate sample with no
risk of contamination. Sollroc offers a range of reverse
circulation hammers and drill bits that provide outstanding
performance coupled with reliability and simplicity. The reverse circulation drilling method has the capability of reaching depths of 500 metres. A pneumatic hammer-like device is used to hammer into the earth to remove rock samples which are then pushed up into the mining machine using compressed air. The samples are collected in a sample bag which is located within the machine. More than one sample bag can be collected which allows for more of a variety of samples to be analysed. Sample bags are usually marked to show the location from which the sample was taken as well as the depth from which the samples are extracted. Adavantages: 1. Direct drilling cost reductions in the range of 25% to 40%. 2. Faster completion of drill programs with quicker delivery of results. 3. Reduced man-hours at the drill with decreased exposure to potential accidents. 4. Reduced contractor activity in the mine reduces mine support burden. 5. Indirect cost reductions gained from a simplified sampling process. 6. Requires less water than diamond drilling. Technical Parameters RC bits Model SRC531
RC hammers
Working principle The on-board compressor delivers power to a pneumatic reciprocating
piston. The piston, in turn, drives a tungsten-steel drill bit
which is purpose designed to be able to crush hard rock. Similar to air core drilling, drill cuttings are returned to
surface inside rods. We achieve this through the use of dual wall
drill rods: an outer drill rod with an inner tube. When compressed
air is blown through the rod, the volume displaces the air, lifting
the samples to the surface. Once cuttings reach a diverter at the top of the hole, they’re
moved through a hose and around the cyclone, which slows the sample
down. From the cyclone the sample goes over a splitter that
delivers a percentage of the entire sample into a sample bag. The
exploration drilling team then collect the samples aligned to the
hole depth and lay them out for the client to log, and then
transport to the lab for assay. Detailed Photo: About us: SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, is a technique of drilling that uses dual wall drill rods that consist of an outer drill rod with an inner tube. By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination,which is mainly used in deep hole exploration and mining grade control.
Delivery Way: By Air, By express or By Sea
