This is one of the very few books which provides, at an advanced level, a general introduction to the state-of-the-art on mine environmental engineering. This work focuses on the elements of the process environment and their interactions with the regulatory and social environments. It systematically presents the major environmental problems of mining operations. Special emphasis is placed on mathematical modeling, computer simulation, expert systems and electronic remote monitoring of mine atmosphere. Filled with illustrations, this work describes industrial practices in detail and discusses government mining regulations on environmental standards around the world. This rare, two-volume publication is a useful text for students, professional engineers, research scientists, and government officials concerned with health and safety in mining operations.
