Inverse problem solution for estimating gas content and gas diffusion coefficient of coal
The authors suggest the method of interpreting experimental data on gas pressure in a pressure flask containing a coal specimen, that allows defining gas content and gas diffusion coefficient of coal. The offered method is based on solving an inverse problem for a set of diffusion equations each fit...

| description | The authors suggest the method of interpreting experimental data on gas pressure in a pressure flask containing a coal specimen, that allows defining gas content and gas diffusion coefficient of coal. The offered method is based on solving an inverse problem for a set of diffusion equations each fitting a certain size within the coal specimen grain-size composition. The numerical experiments have shown that a quantitative estimate of gas content has error not higher than a few per cents, even with input data distortion. |
