Selecting efficient parameters and operation modes for valve-synchronizer of two-side sealing device
Publikováno v:
Journal of Mining Science. 50:94-100
Based on the mine investigations of directional hydraulic fracturing with the use of two-side sealing device, aimed at weakening dirt bands in coal, the researchers have refined the valve synchronizer and eliminated detected vibration defects. The ar
