Spontaneous inrushes of water in underground mines
International Journal of Mine Water, 1986Several water inrushes occurring in Italian underground mines were carefully observed in order to study causes and circumstances, of such events and to investigate the possibility of predicting these inrushes.

Experimental research on water inrush in tunnel construction
Natural Hazards, 2015With the rapid development of underground construction, a large number of tunnels will be built at the positions where unprecedentedly complex geological conditions exist. It results in more and more tunnel water inrush accidents. Study on water inrush becomes more and more important. The water inrush in tunnel construction is the results of water–rock

Water inrush in mines as a consequence of spontaneous hydrofracture
Journal of Mining Science, 2015The authors review water inrushes in mines as a consequence of spontaneous hydrofracturing of surrounding rocks. In the developed hydrofracture model, the fracture grows under the pressure of underground water in the area of reduction in mining-induced stresses.

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.

Water Inrush Risk Evaluation into the Tanjiaba Tunnel
Applied Mechanics and Materials, 2014The Tanjiaba tunnel lies in Hurongxi highway in Hubei Province. There are some middle karstified soluble rocks and a fish pool above the tunnel. To avoid the disaster of water inrush into the tunnel, risk evaluation is necessary to guide the construction. Fuzzy mathematics model is put forward to distinguish potentially dangerous parts along the tunnel.

A study on a water-inrush incident at Laohutai coalmine
International Journal of Rock Mechanics and Mining Sciences, 2013Abstract An underground water-inrush incident at Laohutai coalmine in China was investigated using an integrated approach based on data from microseismic monitoring, hydrochemistry isotope analysis, meteorology, and mining-induced subsidence. It was found that the incident was closely related to a snow storm and the rapid melting of the snow, and was

Mine Stability and Water Inrush in Coal Mine
2020This chapter describes three major parts associated with mining stability and mine water inrush: The first part discusses the stability issues related to rock burst in deep underground coal mines, the second part studies the height variations of water-conducting fractured zone in shallow underground coal mines, and the last part presents a numerical ...

Water inrush dangerousness evaluation of coal floor from SDM
Proceedings 2011 IEEE International Conference on Spatial Data Mining and Geographical Knowledge Services, 2011The floor water inrush is a geology hazard in China. Tt is a complex nonequilibrium and nonlinear evolution process which is affected by many factors. Spatial Data mining (SDM) can reveal spatial patterns and features of water inrush. With the SDM technique, the water inrush dangerousness of 9# coal floor of zhangcun coal mine was evaluated. The result

Water inrush sources monitoring and identification based on mine IoT
Concurrency and Computation: Practice and Experience, 2018SummaryInternet of things (IoT) is applied to water inrush source monitoring network for overcoming complexity and uncertainty of coal mines in monitoring. This study starts from the idea of sensory mines and the architecture of IoT, and describes key techniques in IoT‐based mine water inrush source sensing.
