【摘要】 近年来,随着煤炭开采深度、开采强度、开采速度、开采规模等不断增加,煤炭开采受地下水威胁、危害日趋严重。准确、快速的判别突水水源,是快速采取针对性的治水措施的基础,是确保矿井煤矿安全生产的一项关键技术。本文基于ArcSDE空间数据引擎技术和Microsoft SQL Server设计建立矿井突水水源判别综合信息空间数据库;引入空间数据挖掘技术,将其应用于矿井地下水分析中,并基于Voronoi图方法和DEM方法挖掘了矿井地下水化学类型分布规律和地下水水化学与构造的空间关联规则;研究了常用的矿井突水水源判别模型,重点研究了采用F值定权的模糊综合判别模型,并提出了基于GIS的水温识别矿井突水水源的判别方法,并以此为基础构建了集成水位、水化学、水温于一体的矿井突水水源的综合信息判别模型;基于GIS开发了矿井突水水源综合信息快速判别系统。本文取得的主要结论及成果:建立了简单实用的矿井突水水源综合信息识别流程体系;建立了矿井突水水源判别综合信息空间数据库;潘一矿煤系水具有在研究区北部沿潘集背斜走向一带状区域主要为Cl-K+Na型水,南部一集中区域为HCO3-K+Na型水,其他为HCO3·Cl-K+Na型水的分布特点;新生界下含水具有水化学类型为单一的Cl-K+Na型水的特点;得到了研究区内与潘集背斜距离近的煤系水样的HCO3-浓度值小等规则;在潘一矿,贝叶斯判别准确率为87.23%,神经网络判别准确率为87.23%,灰色关联分析判别结果为80.43%,F值定权的模糊综合评判判别准确率为93.48%,综合信息判别结果表明,水温判别对水质判别已经起到了一定的辅助作用,建立的判别模型具有较好的判别效果;基于GIS开发的系统实现了对相关的各种空间数据和属性数据的管理、矿井突水水源的综合信息判别以及空间数据的三维可视化等功能,系统具有较高的应用价值。本文的创新之处:(1)将空间数据挖掘技术应用于矿井地下水分析中,并基于Voronoi图方法和DEM方法挖掘了矿井地下水化学类型分布规律;(2)提出了基于GIS的水温识别矿井突水水源的判别方法,并构建了集水位、水化学、水温于一体的矿井突水水源的综合信息判别模型;(3)开发了简便、快速、实用的基于GIS的矿井突水水源综合信息快速判别系统;更多还原

【Abstract】 In recent years, with the increase of the coal mining depth, intensity, rate and the exploitation scale, coal mining is under the serious threat of groundwater. Discriminating the source of water-inrush exactly and quickly is the basis of taking countermeasures for water-inrush control, and also is a key technology to ensure the mine safety production.Based on the technology of ArcSDE and Microsoft SQL Server, this paper designed and established a comprehensive information spatial database for discrimination of water-inrush source; spatial data mining technology was introduced and then applied it to the analysis of mine groundwater, and based on Voronoi diagram method and DEM method mined the distribution rules of the hydrochemical types and the spatial association rule of groundwater chemistry and structure; the common models in water-inrush source discrimination was studied, and the fuzzy discrimination model based on F-value weighting was focused on, then a identification method of mine water-inrush source with water temperature based on GIS was proposed, and based on these, discrimination model of mine water-inrush source with comprehensive information which is an integration of water level, water chemistry and water temperature was established; a GIS-based discrimination system of mine water-inrush source with comprehensive information was developed.The main conclusions and results of this paper are as follows: a simple and practical flow system which can identify mine water-inrush source with comprehensive information was established; a comprehensive information spatial database for discrimination of water-inrush source was constituted; the distribution rules of the coal measure aquifer water in Panyi were found, such as the main water-type is Cl-K+Na in Panji anticlinal trend belt area in the north of Panyi, a concentrative region of south in the researh area is HCO3-K+Na, and other areas are HCO3-Cl-K+Na, the Cenozoic bottom aquifer water is single type of Cl-Na+K; rules such as the HCO3- values of samples in coal measure water which are close to Panji anticline are low were obtained; in Panyi mine, the discrimination accuracy rates of Bayes, neural network, analysis of gray related degree; method and fuzzy comprehensive evaluation method with F-value weighting are 87.23%, 87.23%, 80.43% and 93.48%. The results of comprehensive information discrimination show that water temperature discrimination has played a supplementary role to the water quality discrimination, and the model have good effects. The system developed based on GIS realize the management for a variety of related data and attribute data, the discrimination of mine water-inrush source, the three-dimensional visualization of spatial data, and also other functions. It has better actual application value.The innovations of this article are as follows:(1)Spatial data mining technology was applied to analyze the groundwater of mine, and based on Voronoi diagram method and DEM the distribution rules of the chemical types of groundwater were mined;(2)A identification method of mine water-inrush source with water temperature based on GIS was proposed and discrimination model of mine water-inrush source with comprehensive information which integrated water level, water chemical and water temperature was established;(3)A simple, rapid and practical GIS-based system for mine water-inrush source discrimination with comprehensive information was developed.更多还原
