Open Pit Mine Planning and Design: v. 1 Fundamentals: v. 2 CSMine Software Package

Praise for the first edition of this set: 'Students should find it of considerable practical use.' - IMM 'Invaluable Reference ... This book is not a set of miscellaneous papers but a book of detailed planned chapter by chapter guide to open pit design and planning. This is the first of its kind and has had an incomprehensible amount of detailed background research and planning making it an invaluable reference for any professional involved in open pit design, for both beginners and experienced experts. And for those not experienced with mine planning packages it includes CSMINE, a scaled down software of the major mine planning systems which takes you step by step through core basic processes and principles used in resource modelling and open pit design. I highly recommend this book.' - Digby Millikan, Geolite Mining Systems 'Excellent for mining design ... Open Pit Mine Planning is both practical and academic; highly recommended for beginners and experiences experts.' - Amazon.com
