Power Shovels is a celebration of the land leviathans that have inhabited the open pit mines over the past century. Due to their massive size and unbelievable capabilities, interest in these machines extends far beyond their role in the extraction of minerals and precious metals. Author Orlemann focuses on the super stripper and loading class of shovels. Discover how the super stripper can remove vast amounts of earth and place it over a football field away. This book reveals design, engineering, manufacture, assembly, and operation of these modern and massive shovels.

There's no way to guess Quail Lakes was a surface mine. Aside from two deep lakes, there's no evidence that massive earthmoving machines once rumbled across these rolling 1,200 acres of Illinois farmland, lakes, wetlands, and native prairie plants. But the same Quail Lakes that today is home to endangered bird species and hundreds of other wild creatures was a coal mine — a surface mine with pits as deep as 75 feet. Despite what you have heard about about surface mining, Quail Lakes points to something very different. The Quail Lakes you will read about in this book is a microcosm of the realistic and responsible use of land that is possible today. The same property that has yielded crops to feed generations of farmers and livestock also provided coal to generate electricity for homes and businesses. And miners did not leave the land worn out. To the contrary. Thanks to federal mine reclamation laws and passionate stewardship by owners Doug and Diane Oberhelman, the farm fields once again yield bumper crops. Wildlife abounds. And the grasslands and lakes offer wonderful opportunities for fishing, hunting, hiking, camping, swimming, wildlife watching, stargazing, and anything else you can dream of doing in a place where wild animals roam and stars shine bright.
