Full Description
This volume deals with economic aspects of mining companies' development strategies, various mineral deposits development techniques, imitational modeling of mine workings with rock massif, methane extraction technologies during coal mining, geomechanical processes during plow mining, mining transport importance for mineral extraction, massif strain-stress state management using non-explosive destructing materials, and surface mining's detrimental influence on the environment.
Special attention is paid to alternative ways of mining, such as borehole underground coal gasification for extraction of hardly accessible coal and development of gasification plant and development and use of alternative sources of energy such as gas hydrates and sun energy are also disucssed in this book.
This collection of scientific papers will be of interest to mining engineers, engineering technicians, designers, scientific and research personnel, students, postgraduates, and all mining-related professionals working in the coal and ore industry.
