The time-lapse resistivity inversion method is suitable for the regions with continuous conductivity changes, and it can be used to monitor water inrush in those regions.
The fourth aquifer is considered to be a potential threat for coal mining, as it has been proven to be the water supplier for the water inrush in 2011 (Gui and Chen 2007).
The key techniques for the control of water inrush in water-rich faulted zone, jointed fissures and karst passages, and micro-crack water inrush were developed.
Combined with the characteristics of a shortage of inrushing water in the coal mine, we proposed the Sanhejian model of HEMS with its lack of a cold source.
This risk assessment methodology provides a powerful tool for systematically assessing the risk of water inrush in karst tunnels.
A veracious and feasible method is presented to systematically evaluate the risk of water inrush in karst tunnels.
To confirm this consideration, major ion concentrations of two samples (T1 and 2) reported by Gui and Chen (2007) during water inrush in 2001 have been analyzed simultaneously with the data in this study.
With the support of GIS software, a forecasting system for water inrush in Xiamen submarine tunnel was researched and developed, which realized the automated process from basic data input to the result assessment of water inrush.
In this paper, a combination of field measurement, theoretical analysis and numerical simulation were used to study the main control factors of coal mine water inrush in a main aquifer coal seam and its control scheme.
Grouting is a major method used to prevent water and mud inrush in tunnels and underground engineering.
