Abstract.

Safety of works in the heavy loaded longwalls is a pressing scientific and practical problem. Currently, safety of works in the longwalls under the increasing loads is ensured by up-todate powered supports and automatic control of their operation. Method for the powered support control has been improved, and now system of automatic control estimates probability of the gas-dynamic phenomena occurred in the faces and, in order to prevent them, controls and changes pressure in hydraulic cylinders of the powered support elements and, consequently, ensures quick response of the powered support sections to the changed mining-and-geological situation in the face. Thanks to this, safety of works and productivity of the mining operations are essentially increased. This article presents merit, schemes of work and efficiency of the proposed method.

Keywords:

powered support control, pressure in hydraulic cylinders, sections of powered support.
