The cutter advanced by cutting the rock model at a rate of 1.4 m/s at a depth of 5 mm. Total of 150 monitoring points were installed inside the rock model beneath the cutting path, from 1 to 15 mm (see Fig. 5b). The strain rates in the x-, y-, and z-directions were recorded and plotted against monitoring distances.

While conventional disc cutters apply high compressive loads to fracture rock, the ODC system exploits the tensile weakness of rock through "undercutting". The ODC was the brainchild of design engineer David Sugden who collaborated with Australia's Cooperative Research Centre for Mining Technology and Equipment.
The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

engineers envision the new cutting technology will be used in a number of different types of hard rock mining systems: "For example, a compact and versatile unit could cut and load hard rock in a continuous, automated process. Such a system would enable high-speed mine development and faster access to ore deposits.
The Tungsten Carbide rock saw is the perfect rock-cutting attachment for: quarrying; earthmoving; excavation; mining; This saw uses industry standard teeth, commonly used amongst road profilers. No need for blade cooling or watering during cutting.

Trench cutter systems have been used in civil engineering for the least 30 years for the installation of deep cut-off walls, retaining walls and foundation systems. The systems are constantly advanced to achieve greater depth, penetrate through harder rocks a provide a bigger footprint of the cutter. The state-of-the-art equipment can reach down to 250 m …
The laser mining aspects of this build are similar to the Python Mining Build I described previously. Laser Mining: Mining Lasers and Power Distributor: This build has four 2D Mining Lasers and uses a Weapon Focused blueprint on the Power Distributor. This means it can comfortably deplete an asteroid without exhausting its weapon capacitor.
