METHOD OF MANAGEMENT OF COAL-ROCK MASSIVE CONDITION

摘要

Method of management of coal-rock massive condition includes drilling wells and pumping them with solutions. Before injection the coaxial electrode for high voltage pulse discharges is located in the well the encapsulation is then inserted so that the electrode is located in the middle between the borehole bottom and encapsulation, and injecting of fluids into the well is alternated with a series of pulse action on them, the action parameters are selected based on the strength properties of the rock and the physic-chemical properties of the solutions which are pumped.
