Optimal sublevel height and drawing process for horizontal sectional combined mining in steeply inclined, and closely spaced coal seam groups
Abstract The extraction of steeply inclined and closely spaced coal seams induces intense strata pressure disasters owing to cross-layer fracturing and collapse, rendering strike longwall fully mechanised mining unsuitable. An innovative horizontal sectional combined mining method with simultaneous...
