METHOD FOR DEVELOPMENT OF MINERAL FIELD Russian patent published in 2012 - IPC E21B7/18 E21B43/00 

FIELD: mining.

SUBSTANCE: technology includes tunnelling wells 1 to supply a hydraulic fluid into a payout bed 2, where operation wells 3 also stretch. The bed rock is developed with the help of autonomous drilling devices 4, from the mines 5 a bore mud is carried in an upward flow to a head of wells 3, directing further for enrichment in hydraulic pneumatic cyclones 6. Removal of the developed rock from the bottomhole is carried out with the help of an upward gas flow or with the help of the same working fluid spent at the bottomhole, but together with a liquid phase containing inclusions of ore, which is raised to a head of wells 3 by pressure of gas phases produced by a device 4, at the same time a mineral is partially recovered due to introduction of hydrogen and carbon oxide into a gas medium, establishment of conditions for reheating of rock particles, produced by a high-temperature agent of a thermal gas generator of a drilling device.

EFFECT: enhancing effectiveness and reliability of a production process.
