Study on residual gas distribution in long extraction borehole based on negative pressure attenuation effect
In order to study the distribution law of gas residual content in coal seam under long borehole extraction, the formula of long borehole gas extraction model was deduced based on negative pressure attenuation effect. The gas-air model was established by COMSOL simulation software, and the distributi...
