Subsidence induced by underground excavations poses a formidable challenge for mine operators and engineers, as it entails significant disruptions to surface infrastructures, forests, cultivated land, and other areas. This phenomenon occurs by the sinking of the ground due to the excavation of underground deposits and is a well-known issue in both coal and hard rock mining. However, the nature of surface subsidence in hard rock mining differs notably from coal mining. Hard rock mines often encounter an unexpected occurrence of surface subsidence, with sinkhole or pothole phenomenon. The mechanisms underlying sinkhole subsidence are inherently complex, adding challenges in predicting and mitigating them. This paper delves into the understanding of the mechanisms governing sinkhole subsidence and their effects in hard rock mine by employing the discontinuous simulation technique using 3DEC software. The study focuses on a Chromite mine situated in eastern part of India, where instances of surface subsidence have occurred. The results obtained from the simulation are compared with field observations from the mine site. Thus, this paper provides valuable insights on characteristics of sinkhole subsidence and their mechanisms in the hard rock mining.
