CHAPTER 11 Mining Technology - Princeton University

deep underground mining technology shifted its principal focus from a concern for the pro-tection of surface resources to a concern for maximum economic recovery and the conser- vation of the resource. Lessees are required to mine all coal that can be extracted eco-nomically and within the limits of safety and technology so that coal reserves are not left in the ground where they can ...
