Calculation of near-shot pillars
Authors:
Abstract
Mine and laboratory studies by the method of volumetric models established that the operation of the main roof is to some extent similar to the operation of thin slabs. In the general case, the main roof in the mode of its steady motion is a cantilever plate on an elastic base, which rests on the coal massif in front of the mine face and near-shot pillars ...
