Application of directional boreholes for gas drainage of adjacent seams

Coal gas is a serious hazard in coal mines around the world. Additionally, methane-bearing coal gas emissions contribute greatly to the greenhouse effect. If captured and processed properly, methane released during mining can also be used to generate energy. Because methane must be isolated for thes...

Summary:Coal gas is a serious hazard in coal mines around the world. Additionally, methane-bearing coal gas emissions contribute greatly to the greenhouse effect. If captured and processed properly, methane released during mining can also be used to generate energy. Because methane must be isolated for these reasons of mine safety, greenhouse gas reduction, and energy production, there exists a need for enhanced coal gas drainage technology. Here, An et al design a suitable method for gas drainage of adjacent seams by directional boreholes, even when allowing for the immediately caving of adjacent seams during mining.
