Technology relating to the revegetation of lands disturbed by surface-mining is well advanced in the midwestern and Appalachian coal fields. Past accom- plishments demonstrate that the dis- turbances resulting from surface-mining have a potential for management and development. The challenge for the fu- ture will be to develop this potential and to maximize the productivity of reclaimed land. Basic to this concept is the de- velopment of practical methods for pre- mining and post-mining evaluation. Chemical and physical characteristics of the overburden need to be characterized to plan an efficient and profitable mining operation that complements a reclama- tion program designed to achieve an ap- propriate land-management objective. This will return an increasingly larger percentage of the land disturbed by sur- face-mining for coal to economic use. New technology for the reclamation and revegetation of lands disturbed by surface-mining for coal is developing at a rapid rate. This trend will continue as funds for environmental research increase and as more emphasis is placed on en- vironmental protection and land-use plan- ning. The expanding research program has encouraged participation by scientists trained in many disciplines that are directly or indirectly related to surface- mining and reclamation. Although ap- plied research will continue to dominate the research effort, basic research should receive greater emphasis. The abuses of the past should serve as reminders of what may occur when exist- ing knowledge about environmental pro- tection and reclamation is ignored. These past practices are not representative of the mining and reclamation methods in use today. A discussion of present-day reclamation practices is as difficult as giving a resume of agricultural technol- ogy. We can, however, review the basic concepts and procedures that apply to reclamation methods used in the United States. This information, reviewed in context with past practices and the cur- rent research emphasis, suggest the direc- tion future reclamation practices may take. The disturbances resulting from surface-mining for coal may be considered an asset in future land-use planning. Land-management methods can and should be developed to fully utilize the productive capacity of the disturbed land MenosTechnology relating to the revegetation of lands disturbed by surface-mining is well advanced in the midwestern and Appalachian coal fields.
