Method for lifting of magmatic lava to the surface

摘要

Invention relates to the mining industry and may be used for magmatic lava extraction and lifting to the surface for further processing. The disclosed method comprises using a carrier pipe for lava lifting and a smaller diameter pipe for injection of an incombustible gas, wherein the pipes are connected via a disperser. The carrier pipe and the disperser have a plurality of holes of various diameters to ensure efficient lava saturation by gas. The dispenser is preferably designed as cowl concentrically wrapped around carrier pipe. The effect of lava lifting through the carrier pipe is achieved via repetitive lowering and lifting motions of the carrier pipe with simultaneous lava saturation with the gas inside the carrier pipe, which lowers the lava viscosity. After stabilization of the flow velocity of the gas-saturated lava from the carrier pipe, the lava lifting process is changed to lava collection conditions.
