Numerical Investigation of Competitive Methane Transport in Multiborehole Coal Seam Drainage and Its Implications for Borehole Layout Design

Abstract Methane drainage efficiency in coal seams is significantly affected by borehole arrangement, as overlapping pressure sinks in multiborehole systems can redistribute gas migration pathways and reduce the effective performance of individual boreholes. To quantify this inte...

Quantification and Mechanism of the Interborehole Effect in Coal Seam Gas Drainage

Abstract Coal seam gas drainage is crucial for reducing carbon emissions and ensuring safe coal mine production. In engineering, multiborehole combined drainage is widely adopted. However, the interaction among boreholes leads to the complex superposition of their respective infl...
