Study on Numerical Simulation of Overburden Fracture Development Characteristics and Prediction of Water‐Conducting Fracture Zone Height in Shallow Coal Seam Mining

Geofluids
The northern Shanxi mining region, a pivotal coal‐rich area in China, is characterized by substantial reserves of shallow coal seams and distinctive geological mining conditions that exacerbate overburden rock fissure development. This study delves into the mechanisms governing overburden damage and fissure evolution in shallow coal seams using the ...

Adaptive filtering of microseismic data for monitoring a water-conducting fractured zone in a mine

Scientific Reports, 2022
AbstractWater-conducting fractured zones in a rock mass can cause problems in mining. Attempts have been made to monitor their development using microseismic signals. However, due to the lack of prior information, it is difficult to filter out mixed low-frequency interference with traditional denoising methods.

Prediction of the Height of Fractured Water-Conducting Zone: Significant Factors and Model Optimization

Water, 2023
Predicting the height of the fractured water-conducting zone (FWCZ) can be challenging due to their significant grey characteristics and the difficulty in scientifically selecting relevant influencing factors. To address this issue, we utilized the Pearson correlation analysis method and the grey entropy correlation analysis method to identify the ...
