Product Introduction
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.
RC drilling uses a drill bit that features round, protruding tungsten-carbide buttons, to cut through hard rock and earth. The drill rods themselves are hollow and feature an inner tube with an outer barrel (similar to air core drilling).
RC drilling typically produces dry cuttings, as their compressors also pump air ahead of the drill bit, drying the rock in the process.
While the process itself is typically dry, water can be injected when collaring a new hole as a way to reduce dust and assist in lifting cuttings to the surface. When water is injected, an additive gets mixed into the water, known as Super Foam. This makes the cuttings bind to each other, increasing sample recovery.
