Catastrophic Model of Water Inrush from Coal Mine Floor
Applied Mechanics and Materials, 2013The water inrush from coal mine floor is a typical catastrophic process. A catastrophic theory is applied to water bursting in pit footwall for the first time. Through the research on lost stabilization of energy in the floor system of coal mine, a cusp catastrophic model applied to forecast water bursting from coal mine floor is put forward.

Analysis of Mechanism of Water Inrush in Karst Tunnels
Underground Construction and Ground Movement, 2006In China, carbonate rocks cover an area of 3.443 million km squared, which consist of 36% of the nation's territory. It is not unusual to encounter karst related problems in tunnel construction. It is a difficult problem to build tunnels in complex karstified area.

Attribute recognition model for risk assessment of water inrush
Bulletin of Engineering Geology and the Environment, 2017An attribute recognition model of water inrush risk evaluation is established based on attribute mathematic theory and software is developed for risk assessment in a tunnel. In our model, the entropy weight method is applied to analyze the weights of evaluation indexes.

Investigations of water inrushes from aquifers under coal seams
International Journal of Rock Mechanics and Mining Sciences, 2005In many coal mines, limestone-confined aquifers underlie coal seams. During coal extraction from these mines, water inrushes occur frequently with disastrous consequences. This paper introduces the hydrogeological conditions of the coal mines and the potential water inrush disasters from aquifers under coal seams.
