Analysis of Flow Field of Gas Drained from Roof of Working Seams

The paper described the basic principle of gas drainage form boreholes or roadways arranged along roof strike of the working seams and the distribution characteristics of roof rock fractures,analyzed the distribution of gas folw field in the three-dimensional area of the upper corner angle and the goaf of coal face-roof fractures-drainage holes or roadways in the roof before and after practicing gas drainage techniques from roof with flow field theory,and pointed out some key problems need pay attention to in the application of gas drainage techniques from roof。
