What is Mining Subsidence Prediction?
Mining subsidence prediction develops numerical models, influence functions, and probabilistic methods to forecast surface deformations from underground coal extraction.
Researchers apply SAR interferometry, Knothe time functions, and geomechanical models for longwall mining predictions. Key papers include Suchowerska Iwanec et al. (2016) on multi-seam subsidence (94 citations) and Zhang et al. (2020) improving Knothe models (46 citations). Over 500 papers address this subtopic via OpenAlex integration.
Why It Matters
Accurate predictions prevent infrastructure damage in densely populated coalfields, as shown in Xuan and Xu (2017) grout injection control (74 citations). Suchowerska Iwanec et al. (2016) highlight multi-seam risks to surface structures. Ng et al. (2010) SAR mapping (118 citations) enables real-time monitoring for safe operations in regions like Australia's New South Wales and China's Heze City.
Key Research Challenges
Multi-seam subsidence modeling
Predicting interactions in overlapping coal seams complicates surface deformation forecasts. Suchowerska Iwanec et al. (2016) note extraction above or below prior seams alters stress distribution. Numerical models require site-specific geomechanical calibration (94 citations).
Dynamic time-dependent prediction
Standard Knothe functions inadequately capture transient subsidence phases from mining start to closure. Zhang et al. (2020) propose improvements for dynamic surfaces in Heze City (46 citations). Vervoort (2020) identifies distinct phases needing refined time functions (37 citations).
Remote sensing integration accuracy
SAR interferograms face atmospheric and decorrelation noise in subsidence mapping. Ng et al. (2010) use small stacks for accumulated subsidence in Australia (118 citations). Przyłucka et al. (2022) apply InSAR/PSI over 20 years in Poland's Upper Silesia (32 citations).
