The application of Adaline in recognition of mine water quality types

It has an important significance to correctly identify mine water quality types in order to judge water inrush sources.Taking a certain coal mine in North China for example in this paper,two different water quality types of mine inflows from coal seam roof and floor aquifers have been effectively identified by applying Adaline method.Two of four unknown mine water samples are indetified as roof aquifer water,two as floor aquifer water.The convergence and its speed have a close relationship with the choice of step parameter α in the process of neuron learning and training.Besides,with smaller noise background,neuron itself is still able to normally work due to its anti-noise property.
