The Schramm T685 WS truck mounted drill bored a 5.5 inches (14 cm) hole that, on 22 August 2010, was the first to break through to the 33 trapped men, confirming they had survived the accident. [9] The company also manufactured the T130XD air core drilling rig owned by Geotec S.A., a Chilean-American joint venture drilling company.
Hydraulic fracturing [a] is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep rock formations through which natural gas, petroleum ...

Rock drill mounted on a tripod. The large objects on the legs are weights to anchor it down into position. In reciprocating power drills, the drilling cylinder is mounted on a feed-screw, such that as the hole is drilled and the drilling point recedes from the rock face, the drill-bit continues to move into it, while the anchor point (on the tripod or column) remains in place.

Deep hole drilling also differs from normal drilling in that, depending on the drilling process and the drilling diameter, cooling lubricant must be pumped to the cutting edges in large quantities and under high pressure. This ensures good cooling and at the same time good lubrication of the contact areas between the workpiece and the cutting ...
