METHOD OF HYDRAULIC BOREHOLE MINING OF MINERAL RESOURCES AT INCLINED POSITION OF BEDS Russian patent published in 2011 - IPC E21C45/00 

FIELD: mining.

SUBSTANCE: method of hydraulic borehole mining of mineral resources at inclined position of beds involves construction of hydraulic mining and auxiliary wells. Hydraulic mining and auxiliary wells are located in lines along the strike of inclined beds and cross them. Bottoms of vertical hydraulic mining wells are drilled downstream, and bottoms of auxiliary wells having vertical and inclined parts of well, the vertical part is drilled to similar inclined beds and the inclined bed enters similar productive formations, both from upper beds and within productive formations, and is directed towards hydraulic mining wells. Distance between location lines of hydraulic mining wells and auxiliary wells is determined with stability of inter-layer beds-bridges of the worked out area of loose ore beds, and distance between hydraulic mining wells and between auxiliary wells is determined with technical drilling capability of inclined branches towards hydraulic mining wells providing disintegration of loose ores between location lines of hydraulic mining and auxiliary wells of all similar beds subject to development and crossed with hydraulic mining and auxiliary wells.

EFFECT: increasing the scope of mining operations, controlling the mining volume of ore mass as to depth of hydraulic mining well, reducing the scope of construction work of hydraulic mining wells and operating equipment on mining per unit of time.
