【摘要】 摘要：随着信息技术的不断创新和广泛应用,越来越多的领域都选择将行业信息化升级应用作为其前进脚步的重要推动力。信息化创新应用逐渐为大多数行业所接受并集中成为其提高产业竞争的核心手段。我国矿业信息化进程正在发生着悄然的改变,相比以往的装备水平落后、数字化管理能力差以及资源有效利用程度低等矿山信息化发展制约因素,现阶段的矿业已经具备了基本的生产调度数字化管理、高效能设备生产调度应用以及资源综合高效利用的条件与能力。因此,针对矿山发展实际需求,通过在现有信息化水平基础上进行生产调度数据集成、资源开采参数精细化设计以及生产实时预警等矿山多个具体环节的集中研究,使各环节的管理与实施能够统一集成到同一个智能化调度平台当中,从而使得矿业整体调度运行达到一个初步的智能化水平是具有重要意义的。调度是一个非常庞大的体系,其内容涉及到矿山实际生产的方方面面,而每一步的实施和实现又要以客观的矿山需求为准则,因此,调度的实现过程是一个循序渐进的信息化技术创新应用过程。调度实现应该秉持总体设计分布实施的思路,将矿山调度各环节的信息化应用逐步实现后再集成到调度平台当中。本文从矿山调度实际需求出发,着重对调度部分关键技术进行研究,主要内容如下：(1)对调度数据集成方式进行研究。针对矿山数据采集技术特点与采集数据形式,分别对空间信息采集技术、资源信息采集以及采集网络化技术进行了研究。定义了满足调度要求的存储元数据,并进行了数据结构设计,在对调度数据应用进行翔实论证的基础上,实现了数据的稳健、实时、开放式管理与调用。(2)在分析广泛应用的三维建模技术模型构建原理及其特点的基础上,结合数据库存储原理完成了调度模型字典库结构以及数据架构设计通过实际应用检测验证了方法的可行性。(3)借鉴三维可视化仿真技术原理,对调度可视化目标进行了分类研究,并从资源环境可视化建模、模型动态更新以及工况动态仿真三个方面研究了可以实现调度场景动态可视化仿真技术的原理与方法。提出采用“平台+插件”结构体系构建可视化仿真平台,并在VC++和HOOPS开发环境下,成功立实现了三维场景下的调度目标可视化仿真。(4)在全面分析矿山生产要素以及生产技术特点的基础上,总结提出了矿山调度生产知识推理方式。在进行推理体系结构定义、数据结构定义的基础上完成了推理步骤设计,成功开发实现了推理系统并以实际数据进行论证。从调度安全控制角度出发,提出了围绕“人、材、物、产”进行安全知识体系构建的思路。(5)在通过收集矿山生产数据和分析矿山实际需求的基础上,采用模糊预测型线性规划理论对矿山生产资料配置方法进行研究；针对矿山自然崩落采矿方法生产细节进行资源开采特征参数分析与论证,并总结出可供智能调度进行生产数据实时提取的有效途径。研究阐述了通过采用合理方法对资源优化配置以及开采参数进行有效评估的方式来实现矿山调度目标参数合理确定的思路,为不同矿山针对自身实际特点实现有效决策支持提供借鉴。(6)结合三维虚拟仿真技术的原理与应用实现,提出了将矿山生产预警、灾害预警等在虚拟仿真平台中进行应用的思路。利用三维模拟技术实现了假设条件下矿山突水进程模拟,并成功在虚拟平台中开发实现从而达到为调度生产实施提供安全保障的目的。(7)对调度执行系统体系构建和实现方法进行了研究。结合矿山实际调度需求,从生产和安全两个方面阐述调度执行关键技术,根据部分矿山应用需求实现了调度生产和安全执行控制,获得良好效果。更多还原

【Abstract】 Abstract:Constant innovation and broad application of information technology have propelled development in increasing number of fields where upgrading of industrial informatization are witnessed. Being a powerful weapon, innovation and application of information technology are embraced by and integrated in most industries to improve core competitiveness. Similar changes are also taking place in domestic mining field. Mining used to be constrained by backward equipment, poor digital managerial capability and low efficiency in resource utilization. While modern mining is capable of digital management of basic production scheduling, making high efficient equipment dispatching and resource utilization possible. In this paper, such issues as existing informatization platform based data integration for production scheduling, fine design of mining parameters and real time warning system are studied. The aim of the study is to integrate management and implementation of said issues through one single information technology based dispatching platform, which, in light of the demand of the mining industry, is of great significance.As a systematic engineering,mining dispatching involves many down-to-earth issues. Step wise implementation and realization of this huge system hinge upon real demand of mining enterprises. Therefore, realization of mining dispatching is a gradual process with innovation and application of informatization techniques. Principle of overall design and stepwise implementation should be strictly followed in realizing mining dispatching. As a result, informatization of dispatching in individual mining activities should be pursued before final integration is done within the dispatching system. In light of the specific demand of mining enterprise, some key issues of dispatching as presented below are studied in this paper.(1) Considering the characteristics of mining data acquisition technique and the form of acquired data, this paper studies spatial information acquisition techniques, data acquisition concerning mining resource and networked acquisition technique. Proper store metadata and corresponding data structure are defined. Based on articulated proof of dispatching data application, stable, real time and open management and invocation of data was realized.(2) Principle and characteristics of widely applied3D modelling techniques were analyzed. Based on the analysis, database storage principle was used to define dictionary structure of the dispatching system and data structure. Case study then made proved applicability of this method.(3) Categorization of visualized dispatching subjects was made via visualized3D simulation technique. Principle and method of dynamic dispatching view were studied in view of visualized resource environment modelling, dynamic model upgrading and simulation of real time mining activity. The structure of Platform+Plug-In was proposed to build visualized simulation platform. Visualized3D simulation of dispatching subjects was realized within the VC++and HOOPS development platform.(4) Knowledge reasoning method of mining dispatchingwas proposed after a thorough analysis concerning mining production element and mining technique was conducted. The reasoning step design was made after definition of the reasoning structure and corresponding data structure was done. A mining safety production system concentrating on personnel, property, material and production was put forward from the perspective of safety control of dispatching.(5) Mining production resource allocation via linear fuzzy prediction theory was made based on acquired data concerning mining production and demand analysis of mining enterprise. In view of block caving, analysis and demonstration of resource mining parameters was made, based on which an effective method of production data acquisition for intelligent dispatching was proposed. In the study, the thought of proper mining dispatching parameter decision via optimized resource optimization and effective evaluation of mining parameter was illustrated, providing insightful reference to mining decision-making.(6) Application of mining production pre-warning and disaster pre-warning within virtual simulation platform was proposed after an analysis was made concerning3D virtual simulation. Under postulated condition, mining water bursting was simulated via3D simulation technique in a virtual platform. This application was put forward for safety implementation of the mining production dispatching system.(7) Architecture construction and realization of the dispatching system was studied. Key technique concerning dispatching implementation was illustrated from the perspective of both mining activity and safety production. Production scheduling and its safety implementation with satisfactory result achieved were realized in view of certain demands of mining enterprises.更多还原
