Estimating the probability of satisfactory conditions for main entry intersections in a coal mine in weak rock under deep mining depth
The satisfactory condition of underground coal mine intersections is a fundamental requirement for the safe operation of any underground coal mine. A satisfactory intersection condition goes beyond prevention of a roof fall. It must include the ability of the intersection to safely perform its designed function. A satisfactory condition is especially important for those main entries that provide life-of-mine access; both to the current, active areas of the coal mine, and to the future mining areas of the coal reserve or resource. Life-of-the-mine access may be required for decades. The intersections ...
