Abstract
Solutions of the gas flow equation are of particular importance in gas control in coal mines. From this point of view the authors carried out the calculations of pressure distribution around a borehole and gas flow rate into the hole, using the implicit form of the finite difference equation. Also, as an application of the results of the calculation a method is proposed for measuring apparent permeability of coal seam in situ.
