Abstract

Based on the mine investigations of directional hydraulic fracturing using the bidirectional sealing device, aimed at weakening of a dirty band in a coal bed, the researchers have refined the valve synchronizer and eliminated detected vibration defects. The article presents the laboratory analysis of the KS-1 valve synchronizer operation and validates its efficient performance parameters.
