Abandoned Coal-Mined Lands - Nature, Extent, And Cost Of Reclamation - Introduction

The development and use of minerals and mineral fuels are essential to national security and to the maintenance of an expanding economy. As a Nation, we often met these needs but failed to recognize and assess the impact that mining and mineral processing activities have on other natural resources. Currently, the growing demand for energy and minerals is accompanied by an increasing awareness that the provision of these resources must not conflict with society's demand for a clean and habit-able environment. Although present mining and mineral processing activities incorporate, or have under development, technology capable of minimizing environ-mental impacts on land, air, and water, many older operations, particularly in the first half of this century, lacked the technological, social, and environmental insights that exist today. Consequently, a substantial backlog of damaging and potentially damaging conditions remains from such problems as mine subsidence, acid water generation, burning and nonburning waste banks, abandoned surface-mined lands, abandoned underground mine fires, and abandoned mine shafts and oil and gas wells.
