| The construction and mining of a complicated water-rich iron mine is often endangered by water-inrush geologic hazards. So, the water-inrush is a difficult problem which desiderates to be solved effectively as soon as possible. Relying on the"the development and study on the crucial technology of exploring the complicated water-rich mine"(NO.2006BAB02A01), one of the national"11th Five-Year"science and technology supporting projects, on the basis of systematical deep analysis of the geohydrologic conditions in the typical complicated iron mine of Baixiangshan, the thesis has applied the fuzzy mathematics method to the comprehensive evaluation research on the partition of inrush risk of the vertical sections of the eastern and western tunnels of the mining area, and established the physical model of the partition of inrush risk, designed and established the spatial database system of Baixiangshan iron mine, The above research can provide the theoretical and practical help for prevention and control ground water of the water-rich deposit. The main works and contents are as followed:(1) On the basis of the comprehensive analysis of effect factors of the inrush risk, fuzzy mathematics methods are used to establish the model of water-inrush risk assessment, and the synthetical analysis and evaluation are performed. So, the variation laws of water-inrush risk of the eastern and western tunnels have been ascertained, and subarea evolution maps have been completed.(2) By terms of the fuzzy mathematics, based on the partitions of inrush risk of the three levels (-495m, -450m and -390m) and vertical sections of the eastern and western tunnels, the physical model of the partition of inrush risk was established by means of SUPAC, the validity of which also could be illustrated. Then, the spatial database system of partitions of inrush risk of Baixiangshan iron mine was established. The above research can provide the theoretical and practical help for prevention and control ground water of the water-rich deposit. (3) Guided with the systems science theory, structure and function of the spatial database system of Baixiangshan iron mine, was designed through analyzing the aim and assignment of the system, and the request of users and the data pool. This process is based on the comprehensive utilization of computer science, GIS technology and the environment evaluation theory and so on. According to the detailed and systematical demand analysis, this dissertation carved out the data layers and established the database which contains words, figures and table. Data and figures could be exported by request, which would provide the straightforward and reliable data support for the safety production program. |
