Effective Utilization of Horsepower in Mined-land Reclamation Efforts (Part 3).
SAE Earthmoving Ind Conf Peoria Illinois 1977 Apr; :1-12
A search for new tools, methods, and techniques to improve overall efficiency in land reclamation effort was instituted by the Pittsburg & Midway Coal Mining Company (P&M) more than 6 years ago. Although early developments were encouraging, progress was rather slow and very costly. Approximately 2 years ago, the federal Bureau of Mines joined P&M in a program designed to fully test and evaluate early P&M dirt moving concepts as well as others. The resultant specialized reclamation field test has primarily centered on the field test and evaluation of high-volume lateral relocation blades designed to improve dirt handling efficiency in the short distance (less than 50 feet) relocation ranges associated with leveling area- mined spoil banks. Field tests demonstrated the effectiveness of these tools in reducing land leveling and shaping costs by approximately 50 percent compared with conventional bulldozer land reclamation techniques. A total of 1,431 acres of area-mined spoil banks was reclaimed during the test program.
