Diamond Drilling

WHAT IS EXPLORATION DIAMOND DRILLING? Exploration diamond drilling nowdays is most common, fastest and cheapest way of collecting informations of geological structure of the ground. Is used in mining industry to check known and potentional ore deposits. Differs from other geological drilling because a solid core is extracted from depth for examination on the surface. DIAMOND DRILLING […]

Reverse Circulation Drilling

How Does It Work? Reverse circulation drilling (RC) is a method of drilling mechanism is a pneumatic reciprocating piston known as a “hammer” driving a tungsten-steel drill bit. RC drilling utilises much larger rigs , compressors and boosters and depths of up to 500 metres. RC drilling ideally produces dry rock chips, as large air […]

Grade Control Drilling

Grade Control is an important part to any ore reserve. Drillex International have a fleet of RC Grade Control drill rigs suited to multiple commodities and on the open pit mining operations. This type of drilling is utilized to better define the information on the ore grades and ore blocks on the mine in order to optimize ore extraction as well as mine planning and blasting patterns.

Geo-technical drilling

How does it work?

Geotechnical drilling is a type of drilling that is performed as part of the construction process. It’s also under the supervision of a geotechnical engineer who oversees the process to ensure that the drilling meets the requirements of the project. Reason for geotechnical drilling is site analysis. Site analysis is performed to establish whether or not a site is going to be appropriate for construction. This involves drilling to collect rock and soil samples, as well as drilling to determine soil stability and other matters of interest like underground water level or similar. Site analysis is crucial for very big structures, like buildings, tunels, high-ways, dams etc.
