    Borehole mining is done to mine many industrial materials like uranium, iron ore, quartz sand, gravel, gold, diamonds and amber. It is a remote controlled method of underground mining. It is also used in exploration, oil, gas, and water stimulation.

  • Borehole - Wikipedia

    Borehole drilling has a long history. By at least the Han Dynasty (202 BC – 220 AD), the Chinese used deep borehole drilling for mining and other projects. The British sinologist and historian Michael Loewe states that borehole sites could reach as deep as 600 m (2000 ft).

  • Borehole Mining - Kinley Exploration : Kinley Exploration

    Borehole Mining No longer a science project, borehole mining is proving itself as a workable technology that can be applied to a number of industries. Hydraulically jet-cutting a cavern of rock 20 feet in diameter from a drilled bore hole allows this system to recover resources previously uneconomical for open pit or underground mining operations.

  • What are the main methods of mining? American ...

    There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining ...

  • API Advanced Drilling Techniques

    Advanced Drilling Techniques Horizontal Drilling. Horizontal drilling starts with a vertical well that turns horizontal within the reservoir rock in order to expose more open hole to the oil. These horizontal "legs" can be over a mile long; the longer the exposure length, the more oil and natural gas is drained and the faster it can flow.
