Chapter six is devoted to explaining the myths of high horizontal stresses that have been commonly blamed for most roof control problems in recent years. Chapter seven is longwall mining. It contains all the elements of the subjects that I experienced in my research and consulting career. Factors affecting and mine plan designs for multiple seam mining are addressed in Chapter eight. Chapter nine deals with bumps and covers the occurrence, factors affecting, mechanisms, and control of bumps. Entry stability problems including roof and rib falls and floor heaves and their control and supporting methods are addressed in chapter ten.
Chapter eleven illustrates the theories and methods of various types of underground and surface instrumentation. The various types of material models used in computer modelings and model calibration and case examples are included in chapter twelve. Surface subsidence is addressed in chapter thirteen which covers characteristics, factors, affecting, survey, prediction, and damage assessment and mitigation of surface subsidence. Highwall stability the only subject related to surface mining is covered in chapter fourteen. --Book Jacket.
