| Abstract: | In order to increase the permeability and improve gas extraction rate of the outburst-prone coal seam, this paper puts forward the compound-hydraulic technology, introduces the principle and system composition of the technology. The engineering test shows that the gas drainage quantity of compound-hydraulic technology increased by 3.37 times and 2.80 times more than that of single-hydraulic technology, and gas concentration increased 3.35 times and 2.64 times respectively. |
| Keywords: | drilling and reaming integration hydraulic fracturing compound-hydraulic technology enhancing permeability |
