    A drilling rig is an integrated system that drills wells, such as oil or water wells, in the earth's subsurface.Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers.Drilling rigs can sample subsurface mineral deposits, test rock

  • Diamond Core Drilling: Theory, Mechanisms and Applications
    Drill StructureRotary and Wire Line Diamond DrillingCORE ExtractionApplicationsMajor Diamond CORE Drilling LocationsHealth and SafetyCompanies Involved in Diamond CORE DrillingSources and Further ReadingThe term diamond core drilling comes from the ‘diamond bit’ drill used during this process. This drill bit is made up of a group of small, industrial grade diamonds set into a metallic, soft matrix. As the ground is drilled this matrix will wear away and expose more diamonds.The diamond bit is then attached to a drill rod which measures to about 10 feet in length. More sections of pipe can be attached to the top of the drill rod, allowing greatSee more on azomining
