RISBreaking Mechanism and Performance of Coal Subjected to Water Jets Under High In Situ Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of in situ stress on the coal-breaking characteristics of water jets remains unclear, prohibiting the deep coalbed methane (CBM) development. Water jet coal-breaking experiments under different mean three-dimensional ...
Pore Permeability Model Based on Fractal Geometry Theory and Effective Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A reasonable coal seam permeability model should be established to accurately estimate the extraction effectiveness of coalbed methane (CBM). Existing permeability models typically ignore the influence of pore structure ...
