Sneak Peek #9 Drilling machine

A drilling machine is a stationary or self-propelled unit for drilling wells in rocks of various strengths for underground and open-pit mining of mineral resources. There are machines for different purposes: for drilling exploration, mining, including explosive, as well as special wells (degassing, for descent materials, etc.). According to the method of rock destruction, there are percussion rotary and rotary drilling machines. These machines drill wells with a diameter from 100mm to 1000mm to a depth of 200m. Diamond drilling machines used for drilling wells during clearing and exploration in solid and very solid rocks, they have a high frequency of rotation of the drill rod (from 2000 rotations/min and more).

In medium-heavy and heavy self-propelled machines, all working mechanisms and equipment are installed on the platform. Self-propelled drilling machine includes a caterpillar platform, a pneumatic engine or a car, a mast, a rotational-feed mechanism with a drill rod, a compressor, an oil tower, various drive motors with starting equipment, instrumentation and drilling process control equipment, pneumatic transport systems and dust absorption, jacks for machine installation. Mobile (portable) drilling machines have a working body with a drive, brace columns for its installation in the underground workings, a frame on which all parts of the machine are mounted, and a control panel.
