“…The failure of structure on an isolated footing in Eastern Kentucky gives an idea that isolated footing for such backfill soil leads to failure due to cracking through differential settlement 13 . This can probably be eliminated by including raft as a foundation for arresting differential settlement 49,50 .…”

“…Further, different index properties of the soil like liquid limit, plastic limit, shrinkage limit, plasticity index, liquidity index and consistency index also play a vital role to characterize soil deposits and predict their shortterm as well as long-term behaviour under loading. The literature [9][10][11][12][13] on fill soil in opencast coal mines describes that, in general, soils consist of sandstone, siltstone, mudstone, shale, clay and coal [9][10][11][12][13] .…”

“…However, the planned structure started showing signs of failure. Cheeks 13 was appointed as a third party to study the reason behind the settlement of the backfill foundation. He found that water flowing in the ditch during heavy rains have entered the ground with vigour, and whirlpools were formed over the entry area.…”

In this study we collate existing knowledge and suggest a possible methodology for construction on environmentally challenged backfilled mines to restore the sustainability of human settlement. The possibility of reconstruction on a backfill soil with a sustainable solution has been explored. The study highlights the issue of subsidence in backfilled opencast mines through a meticulous understanding of different case studies of construction on mine spoil. The prime focus of the study apart from structural and construction aspects includes the behaviour of heterogeneous mine spoil. Collapse settlement and hydrocompression are discussed to develop an understanding of failure in backfill. The study also incorporates the proposition of possible effective ground improvement treatment for improving soil behaviour through effective utilization of demolished concrete waste material. Further, ground improvement through demolished waste stone column has also been discussed. Finally, a feasible method for constructing a low-rise building on backfilled soil is proposed with available experimental data on bearing capacity. This study along with a comprehensive list of references may prove useful for conducting further research and a thorough understanding of the issues faced by the mining sector in India and other developing countries.
