Borehole mining Borehole mining tool and technology principle schematic Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting ( hydraulicking ).

In some countries, mining is responsible for significant amounts of water use, as well as water waste. Environmentally, potential negative effects of mining can include air, land/soil and water pollution of different kinds. Mining produces potentially hazardous/toxic tailing waste, and can leach toxic chemicals, heavy metals and air pollutants.

In-situ mining (also called in-situ leaching or recovery) is a mining method that's used to obtain minerals like uranium and copper through drilled boreholes into a deposit. In-situ mining works by dissolving naturally occurring minerals that are in a solid state. A leaching solution is pumped into the boreholes where it makes contact with the ore.

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.

Pit mining, one of the most common techniques, hollows out land to extract raw materials. It blasts away land and strips vegetation, leaving the area vulnerable to soil erosion — the wearing away of the topsoil layer of time. Topsoil is necessary for plants to grow, and without it, mining sites can't truly recover.
