WATER DISPOSAL METHOD IN DEVELOPMENT OF BEDDED DEPOSITS BY UPRISING WITH INTERNAL DUMPING Russian patent published in 2021 - IPC E21C41/26 E21F16/00 E02D19/06 

FIELD: mining industry.

SUBSTANCE: invention relates to mining and can be used in the development of flooded inclined bedded deposits. The method for drainage during the development of bedded deposits by uprising with internal dumping includes the formation of a dump by means of a dump, a device below the level of the base of the dump along its front, alternately in each run of catchment sump, and the subsequent pumping of water from the sump into the bosom created between the lower side of the working and the slope of the inner dump. Before opening the deposit and driving a cut trench along its lower side to the length of the intended sinus, the rocks are loosened to the depth of the sinus. The dumping of the external dump is carried out with the creation of a berm between the dump sole and the upper edge of the working - the sinus. The width of the berm is set considering the possibility of movement and operation of excavators with bottom digging.

EFFECT: increasing the filtration capacity of the rock mass below the mined-out space.
