This revision of the standard reference in the field has been updated to reflect the enormous progress made in the sciences of coal mine ground control. Many chapters are completely new and virtually all have been substantially rewritten. The book covers common ground control problems underground, rock properties and in situ stresses, geological effects and roof stability classification and investigation, roof bolting, coal pillars, ground control in longwall mining and multiple-seam mining, bumps, instrumentation, special supports and problems and surface subsidence.
