抄録

This paper deals with the problem of gas drainage by a borehole within a bounded rectangular area under consideration of absorbed methane gas. The gas pressure distribution at dimensionless time, T, which is calculated by the Finite Element Method, shows the combined pattern of radial flow near the borehole and linear flow in the outer area. The approximate expression method by use of the gas pressure gradient function is useful enough for the rectangular area problem like for the circular area problem shown in the first report.
