Study on the depth and pattern of floor failure in closely spaced bifurcated coal seams
At present, most existing formulas for calculating floor failure depth are applicable to specific floor structures. Due to the complex geological characteristics of bifurcated coal seams, the variable relative dip angles and spacing between the upper and lower seams lead to a floor structure that di...
