METHOD OF DOWNHOLE HYDRAULICKING MINERAL RESOURCES

摘要

METHOD OF DOWNHOLE HYDRAULICKING MINERAL RESOURCES A method of downhole hydraulicking mineral resources pursuant whereto production panels are laid out at a deposit, holes are sunk in a longitudinal axis of each production panel, a means of hydraulicking mineral resources -- comprising a monitor and a means of lifting pulp to the surface -- is lowered into each of the holes. A mineral is broken hydraulically by a jet from the monitor, displacing at least once in a horizontal plane within confines of a main sector extending in a direction opposite to that in which a next hole is located, in radial working so that pillars are formed therebetween, An angle of each radial working is about the divergence angle of the jet of the monitor, and an angle the radial working make with each other is decided by the conditions of stability of the pillars between the radial workings during a period of driving a radial working.
