通过调研大量的文献，本文对企业信息系统的发展历程、发展现状和趋势进行了系统的综述，分析了矿山信息系统发展状况与存在的问题。针对目前在信息概念上存在的模糊认识，笔者从哲学角度出发探讨了信息的本质，初步定义了信息的概念，并论述了对信息本质认识的作用和意义。 在矿山信息提取方面，笔者提出了最优频率匹配法理论，初步研究了最优频率匹配法的性质。在此基础上，开展了声波信号与噪声的分离研究，以及去噪处理的探索实践。另外，还利用最优频率匹配法进行了信号压缩的初步尝试。通过建立水泥浆水化热及井中套管柱受力形变的数学模型，本文介绍了如何采用系统模拟技术，来实现固井期间井内温度的预测及套管柱受力形变分析。经过统计分析中原油田的钻头资料，建立了钻头购销规划决策随机模型。通过计算机模拟分析，既解决了钻头在多地层使用时存在的选型优化的难题，也提取得到了各种综合的信息。这些信息的获得，为油田矿区、钻头生产厂家、井队等部门进行钻头购销、使用决策提供了科学的依据。 在信息系统开发方面，通过对目前企业信息系统体系结构中存在的问题和不足的分析，笔者提出了具体的完善意见和建议。定义了企业事务的概念。以信息论和控制论为指导，建立了面向事务设计方法。利用这个方法实现了对企业各种活动的范围、内容、信息流通等，以事务为单位的合理划分与构建。以企业事务系统为基础，定量地描述了企业的信息体系结构。提出了矿山数据库分级设计思想，并在实际的应用中取得了良好的效果。在此基础上，本文定义了面向事务数据库设计的基本概念与设计步骤，介绍了面向事务管理应用软件开发详细的处理逻辑。以喀拉通克铜镍矿信息系统研制开发为例，进行了面向事务设计方法的成功尝试和实践，解决了信息系统开发过程中存在的“瓶颈”问题。另外，本文还在软件通用性和自动化方面进行了深入的探索；通过细致地研究矿山数据表的特性，利用数据库技术实现了矿山输入管理通用应用软件的开发，以及进行表内或多表之间数据动态分析计算的通用化编程，取得了十分显著的效果。 在信息的定量处理和应用上，本文提出了序贯通信模型的概念，中常大月卜们卜士拳位愉大摘要H并对序贯通信进行了初步的分类。推导了矿山语法信息、语用信息和语义信息量的计算公式，开发相应的软件实现了信息量的计算。结合喀拉通克铜镍矿化验结果原始数据，实现了对各种信息量的分析与处理，取得了很有意义的结果。 目前在工程领域己经大量地采用数据库技术，但缺乏系统的理论指导。本文在声波层析成像勘察的工程实践中，通过采取两步走的方式，实现了日常工程技术数据的数据库管理和应用;并探讨了数据库技术与工程应用软件的融合问题，为工程中如何利用数据库技术作了较为系统的探索与尝试。
After investigating numerous literatures, this paper roundly summarizes the course, state and trend of information system, discuss problems existed in mine information management. In allusion to confusion concerning about information, the author analyses information"s essences, principally defines the concept of information. Finally the effect and significance in recognition on what is information are discussed.In study of information abstraction, the author firstly establishes the Optimum Frequency Matching Theory (OFMT), studies its characteristics and rules, applies this method into real signal abstraction and noise elimination of seismic wave"s CT during the detection of underground rock"s fissures and cracks in Xinqiao S and Fe mine. Results are obtained approvingly. Otherwise, how to use OFMT to compress signals is fundamentally investigated. Secondly, The mathematical models of slurry"s hydration heat and oil casing string"s mechanics during cementing are established. Then system simulation technique is used to successfully predict temperatures around casing string, mud and formation, obtains the quantitative changes in stress and strain of casing string. On the base of such information, cement design can be implemented more reasonably. Thirdly, According to the results by analyzing drilling bit data from Zhongyuan Oilfield, a statistical relationship between drilling rate, drilling time and bit quantity used is organized in forms of Rayleigh or self-defined probability distribution function. A discrete random model for bit planning is constructed by use of system simulation theory. The detailed information from systemic simulation can be used as a basis for scientific management and decision for production, selling and bit use in such related departments as bit manufacture, oil company and drilling team.In aspect of developing information system, according to current problems and limitations in information system architecture, idiographic ideas and suggestions for improving this architecture are put forward. Then the concept of Enterprise"s Transaction (ET) is defined. Under the guidance of information theory and cybernetics, the systemic architecture of ET is constructed and modeled quantitatively. In foundation of information system"s physical database, the author introduces a new method which is named Database Grading Technique (DGT). Excellent results are achieved by using this method during developing KalatongkeIVCu and Ni Mine"s management information system. Based on above work, this paper theorizes a new methodology which is called Transaction-Oriented Design Method (TODM) for information system"s strategy formulation and implementation, defines basic concepts of Transaction-Oriented Database Design (TODD) and its detailed logic procedures, accomplishes corresponding software development of information system by means of TODM. Taking Kalatongke Cu and Ni Mine"s management information system as a example, this paper carefully describes methods and steps in database design and its operation system"s development, deeply probes into the all-purpose programme of software, and solves the bottleneck problems in developing information system. Otherwise, the author also excellently realizes the general development of data input management program and dynamic computation within one table or tables such as accounting, synthesizing, aggregating by means of database technique for mine.In quantificational determination and application of mine information, this paper establishes the Order Transfixion Communication Model (OTCM), and basically classifies this model into 32 types of sub-models. Functions to calculate phraseological, pragmatic and semantic information are formulated. Then programs are coded for information computations. Significant results are acquired after processing Kalatongke Cu and Ni Mine"s assay data and explaining or commentating its meaning within such information.Through adopting two-step manner, this
