PROCESS OF HYDRAULIC MINING OF SOLID MINERAL RESOURCES THROUGH HOLES Russian patent published in 2002 - IPC

FIELD: mining industry. SUBSTANCE: body of mineral resources is divided into stalls and stall is divided into blocks. Pulp discharging and hydraulic monitoring holes are drilled and knocked together. Stalls are developed by chambers with wash-out of mineral product in chamber through hydraulic monitoring hole and with lift of pulp to surface through pulp discharging hole of adjacent chamber. Each block is developed by central and several adjacent peripheral chambers, pulp discharging holes are drilled in central chambers. Pulp discharging hole is knocked together with hydraulic monitoring holes in each block through additional hydraulic monitoring hole drilled in close proximity to pulp discharging hole and knocked together with the latter. Pulp discharging hole is knocked together with hydraulic monitoring hole of each next peripheral chamber in block after development of preceding peripheral chamber. Next peripheral chamber in block is developed after fall of overlying rock into worked out space of preceding peripheral chamber. After development of all peripheral chambers and filling up of worked out space in last chamber central chamber is developed with formation of pillar adjacent to peripheral chambers of next block. EFFECT: simplified structural shaping of bottoms of production chambers with preservation of completeness of extraction of mineral product. 2 dwg
