METHOD FOR EXPLORATION, TEST MINING AND EXPLOITATION OF MINERAL RESOURCES AND A SYSTEM TO IMPLEMENT THE SAME Russian patent published in 1996 - IPC

FIELD: mining. SUBSTANCE: two stages are used to working off a pipe. Test mining is the first stage that includes three steps to contour production blocks. Calibration is the first step with filling internal well cavity with heavy liquid until crate part of the pipe comes in contact with overlaying rock. The created working is a pilot-well to place leading needle of breaking tool used at the second step for widening the pilot-well for all the length. At the third step is widened along all the depth. The second stage of pipe working is the stage of working each block with driving pilot-wells. Pipe working comprises two phases from autolithic breccia with high content of diamonds. System for exploration, test mining, and exploitation of minerals includes hydrounit for hydromechanical breaking of the mineral and supplying pulp generated to the surface. Hydrounit is provided with diamond catcher and packaging member used in driving wells with return flushing. The unit includes individual ring packaging sections rigidly installed using sleeves on lower end portion of airlift piping that is the leading needle in driving. Each section is assembled of balls of positive buoyancy, interconnected adjacent balls. EFFECT: higher productivity. 6 cl, 21 dwg
