The voracious appetite of the world for energy and raw materials, coupled with environmental concerns over large surface excavations, ensure that the number and sizes of underground mines will continue to grow. Furthermore, if the 20th century has been the age of skyscrapers in inner cities, then it is projected that the 21st century will be the age of subsurface space. The commercial use of underground space varies from nuclear waste repositories to public facilities. In all such excavations, many pollutants may enter the airstreams including heat, humidity, dust and a variety of dangerous gases. This book covers modern methods of designing and controlling ventilation excavations. The physiological effects of the pollutants are given considerable attention. "Subsurface Ventilation and Environmental Engineering" is directed at the international market and draws on the author's experience of major projects in a number of countries. It should appeal to practitioners, students, teachers and researchers in the fields of mining, civil and mechanical engineering, as well as industrial hygienists with an interest in ventilation and environmental control in underground openings.The treatment reflects the move away from traditional methods of system design towards computer-based techniques.

This book has been written as a reference and text for engineers, researchers, teachers and students who have an interest in the planning and control of the environment in underground openings. While directed primarily to underground mining operations, the design procedures are also applicable to other complex developments of subsurface space such as nuclear waste repositories, commercial accommodation or vehicular networks. The book will, therefore, be useful for mining, civil, mechanical, and heating, ventilating and air-conditioning engineers involved in such enterprises. The chapters on airborne pollutants highlight means of measurement and control as well as physiological reaction. These topics will be of particular interest to industrial hygienists and students of industrial medicine. One of the first technical applications of digital computers in the world's mining industries was for ventilation network analysis. This occurred during the early 1960s. However, it was not until low cost but powerful personal computers proliferated in engineering offices during the 1980s that the full impact of the computer revolution was realized in the day-to-day work of most mine ventilation engineers. This book reflects the changes in approach and design procedures that have been brought about by that revolution. While the book is organized into six parts, it encompasses three broad areas.
