Risk Assessment of Water Inrush in Tunnel through Water-Rich Fault
Geotechnical and Geological Engineering, 2017A fuzzy comprehensive evaluation method based on gray theory is proposed to assess the risk of water inrush in tunnels through water-rich fault. The Grey-Fuzzy method consists of two parts: one is the single factor evaluation matrix which is created by evaluation index and the risk grade membership function, the other one is the weight of each ...

Water inrush and environmental impact of shallow seam mining
Environmental Geology, 2005Shallow seam mining is very common in China for enhancing coal recovery. However, this may cause a series of severe problems in environment and mining safety in some cases, because the alluvium aquifers are directly above the shallow coal seams. Some typical water and sand inrush incidents resulting from shallow mining in China are analyzed.

The Analysis of the Coal Floor Water Inrush Effected by the Fault
Applied Mechanics and Materials, 2014Water inrush from coal floor is some kind of complex geology and mining phenomenon. It is the confined water underlying the coal seams breaking the barrier of the bottom layer, and the water runs into the face of mine in emergencies or delayed, causing natural disasters like discharge increases or flooding.

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.

Development and Experimental Research on a Formula of Water Inrush Coefficient
Applied Mechanics and Materials, 2013Based on analysis of water inrush coefficients developed and applied in deep coal mining with high water pressure, the author proposes that there are some defects of water inrush coefficients in calculation and application. By simulation experiments on the water resistance properties of the aquiclude in a coal seam floor, the author arrived at the ...
