ABSTRACT
Coal mining-induced surface subsidence causes many environmental problems and geological
hazards, including damage to buildings, depletion of water resources, and land desertification. However,
numerous coal resources in China are buried under buildings. To solve these problems, a solid waste
backfill mining (SWBM) technique has been proposed to control the surface subsidence under buildings.
This paper introduced the fundamental principle of the SWBM technique and then presented a model
based on the theory of equivalent mining height (EMH) to predict surface subsidence. In addition,
the compaction effects of backfill materials were obtained through an experiment on the compaction
properties thereof. Afterward, measuring transects were arranged to conduct field observation of surface
subsidence: when the backfill materials are sufficiently compacted, the compression degree is 0.13 with
13% deformation. Moreover, the measured maximum subsidence was 18 mm, which is lower than that
predicted for the maximum deformation of a nearby building. In addition, surface buildings were slightly
influenced by coal mining and no obvious cracks were found. Therefore, this technique provides a new
approach for controlling the surface subsidence induced by coal mining.
