Foreword: Welcome to the 2013 edition German Mining of Best of Germany, highlighting thethe Global compaTechnology Serves expertise of German nies that supply equipment and services to the exploration, mining and mineral-processing VDMA industries around the world. Expertise in engineering is not something that is achieved easily. Many of these companies have histories that date back to the 19th century, and have prospered since then only through investing strongly in research and development. With such foundations, it should come as no surprise that Germany leads the world with its mining-sector technology. Germany's reliance on its own hard- and brown-coal resources led to the development of technology that was suited first to local conditions, and then later transferred successfully to other applications in different parts of the world. However, many people forget that German hard rock mining also led the world in terms of its technology, with a legacy of innovation that continues to this day. Consequently, two of the country's three principal mining institutes are located where they could best serve local metal producers. Innovation, research and development are key features that support German success in world markets. This edition of Best of Germany focuses on work being done by VDMA mining branch member companies in this area, from new chain links or electronic control systems, to energyefficient drives for big mining machines, mills or pumps. We hope that you will enjoy reading this publication, wherever you are in the world. Glückauf!
