Mechanisms and equation improvement for gas seepage in coal seams around boreholes subjected to high-pressure CO2 foam fracturing

Meitian dizhi yu kantan
ObjectiveThe special low-porosity, low-permeability structures of high-gas-content coal seams restrict efficient gas drainage. To address this issue, this study accurately determined the seepage parameters of annularly fractured coals around boreholes ...

Evaluation method of regional anti-outburst effect based on resistivity image

Meikuang Anquan
Coal seam gas pressure is an important indicator for the evaluation of regional outburst prevention effect. Due to the influence of coal seam fractures, it is difficult to accurately measure the residual gas pressure of coal seams.

Temporal and spatial evolution mechanism of large-diameter borehole pressurerelief and permeable gas seepage in high gas coal seam

Meitan kexue jishu
Mine gas extraction has the dilemma of low extraction rate, short effective extraction cycle, and substandard gas pre-extraction concentration. In order to realize the precise pressure relief and permeability of high gas and low gas permeability coal ...
