In the light of the qualities of grouped companies with multi-mine, we presented a proposal for implementing scientific management referred to as center-distributed data warehouse or hybrid data warehouse that local data warehouse is built for each mine enterprise to satisfy the major production management and decision-making while global one extracts information from them. Applying the objected oriented...
The function systems of digital mine for underground metal mines were figured out after analyzing and summarizing to the characteristics of informatization for mines from both domestic and international. The function systems, in the view of actual management of underground metal mines, were integrated with six areas including visualization of geological resources, optimization of design and planning,...
Hidden dangers in system are the main reason that causes accident happen. Using theory of constraints, it achieved the coal mine hidden dangers divided scientifically and reasonably. On the one hand, establishing coal mine hidden danger information's constraint treating flow, it makes the definition of the coal mine worker's responsibility and ability clear. On the other hand, it study on the operating...
Coal mine safety evaluation analyses mine's existent dangerous and harmful factors, and judges mine's potential risks. The evaluation result is propitious to guard against accidents and make management decisions. This paper analyses all kinds of influence elements on coal mine safety, constructs evaluation indexes system, measures weights using AHP, and applies dynamic fuzzy theory in mine safety...
The paper studied on gas prediction problem. According to traditional prediction methods on coal mine safety being offline without dynamic prediction function and the shortcomings in the traditional online learning with least squares support vector machine (LS-SVM), this paper gave an improved online prediction algorithm of LS-SVM. This algorithm was used in gas prediction of some coal mine. By comparing...
