Book Description
Excerpt from Coal Mining Kinks: Compiled From the Regular Issues of Coal Age This difficulty may be overcome by sharpening the drill as shown in Fig. 1, where, it will be seen, the corners have been turned back so that the cutting edge assumes a curved outline. Such a drill point as this will not wedge in ordinary cracks and will thus prevent sticking. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.
