【摘要】 压缩空气是矿山生产的动力源之一,占全矿电力消耗的10%～35%。由于矿山压气系统中涉及的空间信息、技术指标及经济指标等各种信息数量可观,而决策方法尚没有通用的、线性的计算工具,使得对矿山压气系统优化进行决策有诸多困难。特别是云锡区域性矿山这样的特大型矿山,要快速、准确地进行压气系统优化决策几乎不可能。因此,采用辅助决策系统的方法,利用计算机强大的数据管理和分析计算功能,使得决策者在压气系统方案的选择中,能方便地结合决策人的知识和经验,通过辅助决策系统产生的各种方案提供的参考数据,是进行压气系统方案优化一种途径。本文结合云锡区域性矿山现代化信息化规划研究课题,通过对矿山压气系统现状的调查研究,应用系统工程的分析方法,针对区域矿山南部压气系统,在对从压气站址、供气方式、管网布置和设备选型等方面的优化设计方法进行全面分析研究的基础上,开发了矿山压气站网优化辅助决策系统。该辅助决策系统运用系统工程的优化方法,如网络优化理论、决策分析理论等实现了矿山压气站网的优化计算;运用管理信息技术对系统优化决策的相关数据收集管理;通过计算机可视化的交互方式来完成压气站网优化的决策计算,简化了优化计算工作,提高了决策效率。本论文研究中完成主要工作及成果有:(1)通过现场调查,建立了矿山压气设备,管网参数及压损参数的数据管理系统;(2)开发了最小树Prim算法的供气管网结构及长度优化计算C#语言程序;(3)提出了“线段定义-块提取”方法,实现了批量提取管网数据参数的图形数据采集。(4)应用空气动力学理论实现了对供气管径的选择、供气量及压力损失的计算(5)对压气设备的选型进行经济技术方案论证,得出选型方案;(6)为保证矿山压气系统的节能高效运行,提出了在地下矿山建立“压气管理及监控系统”建议方案。采用Visual Foxpro 6.0编写了系统主要界面和计算程序,结合云锡南部区域压气系统数据对本文的研究结果进行了验证。采用本系统进行辅助决策的方案表明,仅云锡南部区域压气系统就可以节约投资43万元,年节约电费98万元。具有节能降耗的社会效益和经济效益。更多还原

【Abstract】 The compressed air is one of the main power in mine production. It generally occupy 10%～35% of the entire power consumption of a underground mine. Because the mine compressed air system involves mass of dada, such as spatial information, technical and the economic indicator etc., the optimization of mine compressed air system is very difficult. The decision-making methods for compressed air system optimization still not have a general way. Especially the YUNNAN TIN GROUP that is such a mine of large scope, it is nearly impossible that to carry on the compressed air system optimization decision-making fast and accurately without a highly effective accurate decision-making tool.Therefore, using the method of assistance decision system, making use of the computer’s powerful data management and the analysis computation function, can combine decision-maker’s knowledge and the experience conveniently when decision-maker choose the compressed air system plan, can avoid making big fault in the process decision-making, the reference data through the assistance decision system which each kind of plan provides, is one path to optimize the compressed air system plan.Combining the program of YUNNAN TIN GROUP region modernization and information plan, through investigating and researching the regional mine compressed air system status of YUNNAN TIN GROUP, applying the systems theory’s analysis method, by analyzing and researching on the Southern compressed air system compressor stations from the site, gas, pipeline network and equipment and so on comprehensively, the author developed the mine compressor stations network optimization decision support system.The aided decision-making system uses optimization methods of project, such as network optimization theory, decision analysis theory and so on, achieves optimization of mine compressor stations network; use information management technology to collect information, completes compressor stations network optimization decisions through computer visualization of interactive, simplifies the optimization work, improves the efficiency of decision-making. The major work and the results this paper completed are:(1) Through investing the status, constructing the data management system of mine compressed air equipment, network parameters and the pressure loss parameters; (2) Making use of the minimum tree optimization theory, achieving optimization of air supply network’s length and structure;(3) Application of theoretical aerodynamics, achieving the calculation of the compressing air supply pipe diameter’ choice, the capacity and the pressure loss;(4) By economic and technical feasibility studies on selection of the compressing equipment, getting the Selection program;(5) To ensure that mine compressor system’s the energy saving and efficient operation, the idea is proposed that the underground mine’s establishment of "a compressed air management and monitoring system".Using Visual FoxPro 6.0 to compile calculation procedure, data from YUNNAN TIN GROUP southern region’s compressed air system verified the results of the test. The system used for decision support program shows that only the southern region of YUNNAN TIN GROUP compressed air system can save￥430,000 of investment and save electricity cost￥980,000, and has energy saving with the social benefits and economic benefits.更多还原
