Abstract

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

Keywords
