FIELD: mining.
SUBSTANCE: group of inventions relates to a system and a method used for generation and application of material for fight against absorption from mine rock fragments when performing operations inside the passage through underground formations. A system for material creation includes a drilling tool connected to a casing string, and a device containing an element for mechanical and hydraulic application of material. This element is adapted for crushing of mine rock fragments. At least some part of the element is moving for displacement, collision, crushing of mine rock fragments to impact surface of the device. Circulating drilling fluid inside a crack formation zone carries mine rock fragments. At least one casing string passes through the crack formation zone of the passage through underground formations and projects in axial direction downwards inside the wall of drilled formations from the most external protective casing string, which lines up the upper end of the passage through underground formations.
EFFECT: element for mechanical and hydraulic material application is capable of catching mine rock fragments for their destruction and formation of material to fight against absorption.
