Efficient Core Drilling Rig Machine for Geotechnical Information Collection in Construction Industry
Description of Core Drilling
Core Drilling is the least invasive type of drilling and is used in difficult or remote areas. A very high standard of quality or representative of the geology can be collected and the information used as the basis for consideration, design and construction based on the potential of the ore body or nature of the geology.
The information is used in modelling to give engineers and geologists a visual representation of what is underground that cannot be seen from the surface. It is a relatively lower cost method due to the drilling method.
Applications
Core Drilling is used in underground mining for delineation of an ore body and resource definition and valuation. It is used in tunnel infrastructure to ensure that no methane pockets of air are mined into, as well as for water bearing areas that could potentially flood the underground infrastructure. In addition, Core Drilling is used for the geo-technical evaluation of the nature, material properties and type of rock for the purposes of designing a certain size shaft, tunnel or stoping panel to be used for the calculation of the type and amount of rock support required.
In the construction or urban infrastructure industries, Core Drilling is mainly used for geo-technical information in the design of foundations for bridges, buildings, tunnels, etc.
