Abstract
This paper recalls that the development of methods of winning to the rise in steep, thick seams with stowing is hampered by the problem of maintaining stability in the overlying rock mass. Examined in succession are the following factors which affect roof kinematics: seam thickness, abutment pressure, pack-compression characteristics, width of dirt band, the method of winning, the rate of coal-face advance, etc. Plans are under way to evaluate the stability of the overlying solid according to the value of deformation relative to the compression at which the solid breaks-up around its edge. This value amounts to 3-4% for highly-resistant types of coal and 1.2-2% for low-resistant coal. The practical application of the technique is discussed.
