The normalization process of the multi-field information from a coal mine water-inrush model test

• 摘要：

  Based on the normalization algorithm whose transform function is linear, the multi-field information collected in a coal mine water-inrush model test such as displacement, seepage pressure, stress and apparent resistivity was mapped to values between zero and one in order to eliminate the differences of dimensions and value ranges. In this way the normalization curves of the multi-field information were described in the same coordinate system, which were contrasted with the original curves to analyze the changing tendency and relationship among different variables. It is found that seepage pressure, apparent resistivity and stress are the ideal information resources for water-inrush prediction; abnormal fluctuations of seepage pressure appeares long before the occurrence of water inrush; the apparent resistivity and stress increases suddenly before the occurrence of water inrush, and the apparent resistivity change earlier than the stress.
