The report outlines the key requirements for an advanced underground coal mining system for the year 2000, focusing on Central Appalachia. The system must be cost-effective, improve miner safety and health, minimize environmental impact, conserve coal, and maintain high production standards. The goal is to achieve a return on investment, reduce injuries, meet health regulations, protect the environment, and recover coal efficiently. The study found that these goals can be met without sacrificing production costs.
