Modern American Coal Mining: Methods and Applications covers a full range of coal mining and coal industry topics, with chapters written by leading coal mining industry professionals and academicians. Highlights from the book include coal resources and distribution, mine design, advances in strata control and power systems, improvements in surface mining, ventilation to reduce fires and explosions, drilling and blasting, staffing requirement ratios, management and preplanning, and coal preparation and reclamation. The text is enhanced with 11 case studies that are representative of underground and surface mines in the United States. Narrative descriptions and appropriate mine plans are presented, with attention given to unique features and situations that are addressed through mine design and construction. A useful glossary is included, as are many examples, figures, equations and tables, to make the text even more useful.
Mining is the foremost source of minerals that all countries find essential for maintaining and improving their standards of living. Mined materials are needed to construct roads and hospitals, to build automobiles and houses, to make computers and satellites, to generate electricity, and to provide many other goods and services that consumers enjoy. The high tech industries and even the better known resource industries are all dependent, in some way, on the mining industry. But exploring, extraction and processing of minerals require big material and labour costs and there is a big number of acute problems to face, such as: environment and water pollution, worsening of mining-geological conditions, depletion of minerals that can be extracted only by conventional methods, rock pressure manifestation, big depths of the deposits and transportation of the minerals on the surface. In order to find modern solutions there is a big number of scientists and engineers all over the world dedicating their research to most current problems and inventions of innovative technologies and techniques in mining. Some of the most important results of such research is presented in this book and covers the following topics: management of strain and stress state of the massif, underground coal gasification, substantiation of rational parameters of various types of support, ventilation in underground openings, design of mine workings and other vital questions.
These research papers also cover a spectrum of innovative technical solutions, including computer-controlled mining equipment, remote monitoring of air quality, and virtual reality training systems.
This textbook sets the standard for university-level instruction of mining engineering principles. With a thoughtful balance of theory and application, it gives students a practical working knowledge of various concepts presented. Its utility extends beyond the classroom as a valuable field reference for practicing engineers.
The U.S. Bureau of Mines examined previous research on rib stability in an effort to develop a practical approach to understanding, characterizing, and controlling weak rib conditions in underground coal mines. Because success in stabilizing ribs depends on a basic knowledge of how weak ribs behave, the report reviews the mechanics of rib failure and the relationship of coal mine geology and pillar constraint to rib instability. Strategies for choosing an effective method of rib support are considered, and various rib support methods are discussed. Finally, the report documents techniques for monitoring ribs and use of models to assess rib stability; such monitoring and modeling can also help determine the most effective method for roof support.
Covers basics of wind-electric systems, water-pumping windmills, and a wind furnace. Focuses on how to build appropriate windmills in many different situations, on all kinds of sites.
