Physical simulation and drilling optimization design of hydraulic cavitation and permeability enhancement in Wuhushan Coal Mine

For the problems that poor gas permeability and strong gas adsorption in the coal seams of Wuhushan Coal Mine leads to poor drilling and extraction efficiency and low extraction rate, physical simulation and on-site testing methods were used to numerically simulate the changes in drilling parameters...
