Calculation of the Height of the Water-Conducting Fracture Zone Based on the Analysis of Critical Fracturing of Overlying Strata

Sustainability, 2022
Accurate division of the water-conducting fracturing zone (WCFZ) in the mining overburden serves as an important basis to evaluate the stability of coal mining under water bodies. Research on the WCFZ is conducive to controlling surface subsidence and realizing safe coal mining under water.

Predicting the Water-Conducting Fracture Zone (WCFZ) Height Using an MPGA-SVR Approach [PDF]

Sustainability, 2020
Mine water that inrushes from coal-roof strata has always posed a substantial threat to mining activities every year. Therefore, an accurate prediction of the water-conducting fracture zone (WCFZ) height in the mining overburden strata is of great significance for the prevention and control of mine water accidents.

Prediction of coal mine water conduction fracture zone height based on integrated learning model. [PDF]

Sci Rep
Abstract To enhance the accuracy of predicting the height of water-conducting fracture zones (WCFZ) in coal mines, this study proposes a novel stacked ensemble learning model. The model integrates XGBoost and Support Vector Regression (SVR) as base learners, with CatBoost serving as the meta-learner, forming a two-layer architecture.
