Analysis on Subsidence Law of Bedrock and Ultrathick Loose Layer Caused by Coal Mining

Geofluids, 2021
In the process of coal mining, when the buried depth is large and the loose layer is thick, the ground subsidence tends to be abnormal, thus causing great damage to the surface ecological environment.

Prediction Modeling of Ground Subsidence Risk Based on Machine Learning Using the Attribute Information of Underground Utilities in Urban Areas in Korea

Applied Sciences, 2023
As ground subsidence accidents in urban areas that occur due to damage to underground utilities can cause great damage, it is necessary to predict and prepare for such accidents in order to minimize such damage.

A time function-based prediction model of mining subsidence: application to the Barapukuria coal mine, Bangla

Scientific Reports, 2022
Coal mining may lead to ground subsidence in a long term and is widely distributed, which can cause environmental damage and other disasters. Predicting the dynamic process of ground subsidence in real time is very important for offering theoretical or ...
