| Abstract: | For the issues that low permeability coal seam gas extraction does not have obvious effect and low gas extraction rate, we propose the perforating technology which has been applied maturely in oil and gas ex- ploration to increase coal seam porosity and improve gas extraction effect. Through analysing the feasibility of perforating technology applied in gas extraction and improving gas extraction rate, we can provide the evidence for the next step to carry out field testing and theoretical analysis roundly. |
