METHOD FOR EXTRACTION OF MINERAL RESOURCES AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2005 - IPC

FIELD: mining industry.

SUBSTANCE: method includes opening productive bed by product slanting well, casing the well by pipes column, mounting well block with concentrically positioned pipes columns, lift and hydro-monitoring headpiece, hydro-monitoring erosion of bed and raising formed mixture of rocks by said lift to surface. According to method, opening of productive bed is performed using product slanting well and its casing is performed by displacing outer pipes column of well block along well axis and concurrent rotation of inner pipes column, hydro-monitoring headpiece is inserted inside outer column of pipes of well block, and during erosion of bed it is pulled out of outer pipes column of well block. Device for realization of said method is made in form of well block, including as common parts concentrically placed pipes column, outermost of which is casing column of well, and inner one is provided with headpiece with lift, hydro-monitoring headpiece and pressurizing element, and portal in form of two-passage swivel for feeding water and draining pulp. Pressurizing element is mounted at end piece above hydro-monitoring headpiece and is made in form of cylindrical shelf. To limit movement of inner pipes column relatively to outer pipes column, at lower end of outer pipes column a bushing is mounted with possible interaction with cylindrical shelf, outer diameter of which exceeds inner diameter of bushing.

EFFECT: higher efficiency, lower costs, lower laboriousness.
