摘要：

It's shown that forecasting methane emission of production faces and development workings in coal mines which providing aerological safety of underground coal mining is based at the complex description of gas motion in porous mediums which suitable reflecting geotechnological processes and physical conditions specified by initial and boundary conditions. It's recommended continuing improving method of designing ventilation of gas-bearing development workings and production faces at the base forecasted evaluating methane emission dynamics and dynamical method of calculating air quantity. It's noted that the technology of defining methane danger of development workings and production faces must take into account influencing at the one of ventilation regime, filtration and diffusion parameters of methane transfer.
