| Summary: | The article presents the research results of parameters of the mud pulse method the loosening of outburst-hazardous coal seams in the faces of development workings system APSS-1. The results of the monitoring and evaluation of the effectiveness of pulse loosening a coal seam in static and pulsed mode of injection fluid, the main provisions of the developed techniques and additions to methods of acoustic control with a view to their use in hydroimpulsive impact. It is established that application of pulsed injection of fluid leads to a decrease in the active phase of the process pulse loosening a coal seam, to increase its efficiency and increase the speed of the output. |
