Book Description
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.

Book Description
Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.
