FIELD: mining.
SUBSTANCE: used in the development of mineral deposits, represented by soaked rocks. Such deposits include, for example, a number of diamond-bearing pipes in the Arkhangelsk region. The method includes opening the deposit by vertical mining, preparation of the mined area, creation of an artificial roof over it, subsequent hydraulic destruction of the rock mass, delivery and output of the rock mass to the surface. Mining is carried out by stages. Each stage is divided into chambers located around the opening vertical mining. Before testing each chamber, an artificial inclined broken bottom is formed from a hardening material. Slots pass between the chambers, which are filled with a hardening material. After solidification of the hardening material of the bottom and on the contour of the mining chamber above the bottom, a process working excavation is created, which is completely filled with liquid - water with damming. As the rock mass soaks and peels off, it is delivered and output to the surface. After mining the entire chamber, the bottom is cleaned, and the chamber cavity is backfilled.
EFFECT: simplification of mining operations, the separation of the useful component from the rock during mining and transportation.
