Calculation of stresses in inter-chamber pillars
Abstract
In the practice of construction and operation of mines, shafts and underground structures one of the urgent tasks is the calculation of pillars. Its solution is complicated by a variety of types of pillars and conditions of their operation. The nature of operation of inter-chamber pillars depends on a number of parameters, the most important of which, other things being equal, are: the structure of pillars, the properties of the rocks composing them, the depth of work, the type of links between pillars and the host rocks, the ratio of pillar sizes, etc.
