Article Preview

Nonlinear methods can be used to identify inrush water rapidly. Yet to identify the mixture water must be combined with water chemistry analysis. Take 9 levels inrush water in Tangshan Mine as an example, according to routine water test data, nonlinear methods, including gray correlation analysis, stepwise distinguishing, neural network, were used to determine water supply quickly, and the results were compared. On the basis, the indicators of piper three-line graph, SI, PCO2 determine the composition of the mixed water and supply channels. The results showed that the main recharge sources of 9th levels inrush water are alluvial and Ordovician limestone water, and infiltrating surface water. Possible ways to supply water are the tectonic fracture, gob, leakage shaft, closed adverse drilling.
