The laser drilling process involves the use of an infrared laser (of surgical grade at a wavelength about 1064 nm) to bore very fine holes (less than 0.2 millimeters or 0.005 inches in diameter) into a diamond to create a route of access to a black carbon crystal inclusion.
For diamond mining in northern Canada to be more sustainable, planners need to have an idea of what values are the most important to protect. This is usually done through a process called land use planning which identifies areas of the land important to local people, and important to the health of the environment.ventually, the hole runs out of the stuff you were digging up. That is not sustainable. But as an activity, diamond mining can be made to contribute to sustainability. Firstly, we recognize that development is necessary to eliminate poverty and to provide economic choices for northern peoples.
