State-of-the-art techniques for backfilling abandoned mine voids.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, IC 9359, 1993 Jan; :1-17
Abandoned underground mine openings are susceptible to collapse because of the mining methods used, the character of the overburden, and the typically large wide entries with minimal roof support. The final effect of the collapse of the underground workings is surface subsidence. To reduce the probability of subsidence, methods to backfill the mine void with various types of materials have been developed. The paper describes the available technologies for subsidence abatement and discusses their operation and application.
