Scientific drilling into the Earth is a way for scientists to probe the Earth's sediments, crust, and upper mantle.In addition to rock samples, drilling technology can unearth samples of connate fluids and of the subsurface biosphere, mostly microbial life, preserved in drilled samples.
An underground rocket or rocket drill is a device for rapidly drilling holes through soil and rock of varying composition at rates up to 1 metre per second [1] [2] by utilising supersonic jets of hot gases. It was developed by Russian engineer Mikhail Tsiferov in 1948.
The main level for science is the 4850 Level, which can be accessed through the Yates and Ross shafts. At 1,490 meters, SURF is the deepest underground laboratory in the U.S. For experiments on the 4850 Level, the average rock overburden is approximately 4,300 meters water equivalent (m.w.e.). This depth provides significant protection from ...
Boring is drilling a hole, tunnel, or well in the Earth. It is used for various applications in geology, agriculture, hydrology, civil engineering, and mineral exploration. Today, most Earth drilling serves one of the following purposes: return samples of the soil and/or rock through which the drill passes; access rocks from which material can ...
Producing boreholes with wide range of diameters or drilling in water environment can be mentioned. The research team from Slovakia has developed drilling concept based on utilization of electrical plasma. The core of the research is held in Research Centre for Deep Drilling which was opened in the premises of Slovak Academy of Sciences.

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.
