In the recent three years, diamond drilling has been extremely widely used in the Northwest Bureau of Geology. For example, diamond drilling was carried out in 10 geological surveys between 1961 and 1962. Some of the boreholes in the Cibinoir geological prospecting team reach a depth of 600-800 meters and the Mens Guell-1100 meters.
