2 #0183;#32;Drilling machinery, equipment used to drill holes in the ground for such activities as prospecting, well sinking (petroleum, natural gas, water, and salt), and scientific explorations. Drilling holes in rock to receive blasting charges is an operation in tunneling, mining, and other excavating.
Mining Drills Mining drills are used to reach ores that are deposited on the lowest part of the ground. The most precious ores require heat and pressure to reach a higher grade, and it can only be done if these ores are deposited several meters underneath the surface of the earth.
The technical demands of underground hard rock mining operations are higher than for open cut, which is why we are collaborating with key mining machinery and technology manufacturers (OEMs) on three automated and continuous mining vehicles designed to create far greater rock stability and less variance in the quality of the ore we extract.
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
