Height measurement of the water-conducting fracture zone based on stress monitoring
Arabian Journal of Geosciences, 2021In 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.

The height of fractured water-conducting zone in undermined rock strata
Engineering Geology, 2011The 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.

Water flooding disasters are one of the five natural coal-mining disasters that threaten the lives of coal miners. The main causes of this flooding are water-conducting fractured zones within coal seams. However, when resistivity methods are used to detect water-conducting fractured zones in coal seams, incorrect conclusions can be drawn because of ...

The Height of Water-Conducting Fractured Zones in Longwall Mining of Shallow Coal Seams
Geotechnical and Geological Engineering, 2015The height of the water-conducting fractured zone is of significant importance for both the prevention of water inrush induced disasters and the design of longwall mines. To ensure the mining safety of shallow coal seams under water-rich aquifers, an approach for forecasting the height of the water-conducting fractured zone is proposed by analyzing the
