  • Coiled Tube Turbodrilling: a proposed technology to optimise drilling deep hard rocks for mineral exploration

    The need to drill deep boreholes more efficiently for mineral exploration has raised the attention to investigate the feasibility of recent drilling technologies for such applications. The two principal methods of Reverse Circulation (RC) and diamond core drilling are usually used in combination by mine operators are subjected to certain limitations and inefficiencies. Considering that delivering ...

  • Installing gravity sewer in tough Georgia rock

    It took a contractor who was receptive to an innovative new installation approach, a good deal of patience and a whole lot of determination — after two previous attempts by other contractors using drills and air hammers were unsuccessful — to finally conquer a pesky 800-foot (243.8 m) stretch of tough Georgia blue granite. Hence, project owner Coweta County Water and Sewer Authority ...

  • A fuzzy logic based classification for assessing of rock mass drillability

    This paper describes a fuzzy classification system for evaluating of rock mass drillability. Six parameters; Uniaxial Compressive Strength (UCS), joints dipping, Mohs hardness, joints aperture, joints spacing and grain size have been used. In this fuzzy system, each rock mass is classified into five modes from very poor to excellent condition. As a case study, 15 rock masses in two mines in Iran ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

  • Grindex pumps bedrock for more trains

    Dewatering a big tunnelling project demands both reliable dewatering pumps and a well planned sedimentation system. This case study from the Swedish railway project Ådalsbanan shows a good example of this. Ådalsbanan is one of the biggest railway projects in Sweden and comprises investments of 6600 MSEK. It stretches as far as 130 kilometres, from the city of Sundsvall to the ...

  • Oil & Gas exploration access road (Orito - Putumayo, Colombia) case study

    Background: Ecopetrol, one of the principal petroleum companies in latin america, has been expanding its reach deeper into the forests of Colombia. Drilling exploratory wells in remote locations such as the Putumayo basin concurs with a very aggressive growth strategy. The area around Orito is an extremely dense, undulating forest with poor soils and wet subgrades, nearly impossible to drive ...
