不同瓦斯压力条件下钻孔有效抽采半径的模拟分析OA
Simulation analysis of drilling effective radius of extraction under the condition of different gas pressure
本文通过COMSOL Multiphysics对模拟原始瓦斯压力1.5MPa和瓦斯压力1MPa钻孔抽采过程中钻孔有效抽采的变化，说明不同区域钻孔有效抽采半径的不同，以此为不同区域的钻孔布置间距的确定提供依据。
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.
