Height measurement of the water-conducting fracture zone based on stress monitoring

Arabian Journal of Geosciences, 2021
In North China, waterproof coal pillars contain massive coal resources, which cause a huge waste of resources. With the reduction of high-quality recoverable reserves, the mining of coal resources threatened by water and sand inrush disasters has been gradually emphasized in recent years.

Investigation of the Height of Fractured Water-Conducting Zone: A Case Study

Geotechnical and Geological Engineering, 2021
At present, the prediction of the height of fractured water-conducting zone has become increasingly important for the safety of underground mining, since the mining depth increase continuously. According to mining conditions and petrophysical parameters of overburden strata, a suitable numerical model is established by FLAC3D to carry out numerical ...

The height of fractured water-conducting zone in undermined rock strata

Engineering Geology, 2011
The height of fractured water conducting zone is of significant importance for the safety of underground mining. Because of the conspicuous discrepancy of the height of fractured water conducting zone in Bulianta Coal Mine as predicted by the traditional method with those observed in practice, a systematic research has been carried out.
