| Abstract: | This paper introduces the types of the coal texture and the occurrence of the coal-bed gas in China,points out that the content of the coal-bed gas in outburst coal seam is higher while the gas brust is easy but the gas exploitation is difficult,and probes into the feasibility of damaging the seam floor into fissured body by using the effect of the loose blasting and making the diffused coal-bed gas move into the boreholes through the floor cracks for extraction and utilization. |
