In conjunction with association rules for data mining, the connections between testing indices and strong and weak association rules were determined, and new derivative rules were obtained by further reasoning. Association rules were used to analyze correlation and check consistency between indices. This study shows that the judgment obtained by weak association rules or non-association rules is more accurate and more credible than that obtained by strong association rules. When the testing grades of two indices in the weak association rules are inconsistent, the testing grades of indices are more likely to be erroneous, and the mistakes are often caused by human factors. Clustering data mining technology was used to analyze the reliability of a diagnosis, or to perform health diagnosis directly. Analysis showed that the clustering results are related to the indices selected, and that if the indices selected are more significant, the characteristics of clustering results are also more significant, and the analysis or diagnosis is more credible. The indices and diagnosis analysis function produced by this study provide a necessary theoretical foundation and new ideas for the development of hydraulic metal structure health diagnosis technology. 展开更多

The nontraditional mining industry is an important part of nontraditional mineral resources projects. It is a new mining industry focusing on the application of new science and technology, producing high value added outputs, offering comprehensive services, protecting the environment and saving energy sources. This paper discusses main principles of two kinds of nontraditional miming technology: the drilling hydraulic fracturing and drilling hydraulic mining applied to the coalbed methane production. Furthermore, this paper introduces the characteristics and application of these two kinds of technology. 展开更多
