| Abstract: | Compound technique of perforating can effectively control the perforating direction and the fracturing expansion. The feasibility of this technique used in rupturing coal seams is analyzed. The experiments of perforating and fracturing are carried out on coal samples and the experimental effects are satisfactory. Compound technique of perforating and fracturing is promising in coal seams. |
