摘要
Abstract
Through COMSOL Multiphysics to simulate the original gas pressure 1.5 MPa and the gas pressure 1 MPa that borehole drilling effective extraction radius change in the process of extraction, explain the differences about borehole radius of effective extraction between the different regions, to provide basis for the confirmation of the borehole layout spacing in different areas.关键词
