resulting from highwall mining is a necessary facet of a ground control investigation. INTRODUCTION Auger and highwall mining has evolved from a secondary production method to become an integral part of many surface mining operations throughout the U.S. and the world. Auger mining in the Appalachians began sometime in the mid 1940s when

Ground Control Design For Highwall Mining

Introduction Auger and highwall mining continues to grow in importance as a coal production method from surface mines. Currently, there may be up to 60 highwall mining systems and as many as 150 auger mining systems operating in the nation’s surface coal mines. Recent estimates suggest that upwards of 45 million clean tons

Mining - Surface mining | Britannica

In strip mining a long, narrow strip of mineral is uncovered by a dragline, large shovel, or similar type of excavator. After the mineral has been removed, an adjacent strip is uncovered and its overlying waste material deposited in the excavation of the first strip. Since strip mining is primarily applied to thin,...

Surface auger mining at Rietspruit Mine Services (Pty) Ltd

A number of high wall mining methods were developed over the years to mine coal reserves exposed on the high walls created during surface mining. The auger mining system was initially developed in the early 1940s in the United States of America. High wall mining is a method of recovering coal from seam
