发布时间：2018-09-13 09:40
【摘要】：作为矿井五大自然灾害之一,矿井水灾一直威胁矿井的安全生产。我国矿井的地质条件复杂,是世界上水害最严重的国家之一。近年来,随着矿井的采掘深度不断加大,其对地下水的扰动影响也进一步增大,突水事故发生的概率和突水强度也呈现出增强的趋势。鉴于井下水灾事故的急剧性,一旦发生水灾事故,需要受困地区的作业人员尽快的撤离到安全地点,以减少作业人员的伤亡。基于此种考虑,本文研发了矿井水灾发生时的紧急避灾系统,本系统是安全避险“六大系统”的重要组成部分之一,能够在一定程度上提升矿井的应急避灾能力,对数字化矿山的建设具有一定贡献性的意义。第一章为绪论,其中首先分析了本文的研究背景、目的和意义,然后讨论了国内外研究现状。第二章为矿井充水条件分析,包括矿井充水水源分析、矿井充水通道分析、矿井充水强度分析、矿井的水文地质类型分析以及突水的巷道内的流动及其演化规律。第三章为矿井水害避水路线的比选与改进,首先讨论了避灾设计的原则,基于对最短路径算法的比较,选取了传统的迪杰斯特拉算法作为解算工具;然后针对矿井避水的具体要求。本文对传统的迪杰斯斯特拉算法进行了改进,用当量路径代替实际路径,这样可以综合考虑各个巷道的通行效率。第四章为巷道网络模型的建立与分析,其中首先分析了巷道网络模型的数据来源及网络模型的特点,然后确定了巷道网络参数的存储结构。第五章是矿井壁水系统的设计与实现,借助Microsoft Visual Studio 2012作为开发环境,使用Visual Basic.NET作为开发语言,设计了紧急避险系统,然后基于某矿的工程地质材料,在该矿上进行了应用。
[Abstract]:As one of the five natural disasters, mine flooding has been threatening the safety of mine production. The geological condition of mine in our country is complex, and it is one of the countries with the most serious water damage in the world. In recent years, with the increasing of mining depth, the disturbance of underground water is further increased, and the probability of water inrush and the intensity of water inrush also show an increasing trend. In view of the sharp nature of the underground flood accident, once the flood accident occurs, it is necessary for the operators in the trapped area to evacuate to the safe place as soon as possible in order to reduce the casualties of the workers. Based on this consideration, an emergency disaster avoidance system is developed in this paper, which is one of the most important parts of the "six systems" of safety and avoidance, and can improve the ability of mine emergency disaster avoidance to a certain extent. It has certain contribution significance to the construction of digital mine. The first chapter is the introduction, which first analyzes the background, purpose and significance of this paper, and then discusses the current research situation at home and abroad. The second chapter is the analysis of mine water filling condition, including mine water source analysis, mine water filling channel analysis, mine water filling intensity analysis, mine hydrogeological type analysis and water inrush roadway flow and its evolution law. The third chapter is the comparison and improvement of mine water disaster avoidance route. Firstly, the principle of disaster avoidance design is discussed. Based on the comparison of shortest path algorithm, the traditional Dijstra algorithm is selected as the solution tool. Then the specific requirements for mine water avoidance. In this paper the traditional Dijess Stella algorithm is improved and the equivalent path is used to replace the actual path so that the efficiency of each roadway can be considered synthetically. The fourth chapter is the establishment and analysis of the roadway network model. Firstly, the data source of the roadway network model and the characteristics of the network model are analyzed, and then the storage structure of the roadway network parameters is determined. The fifth chapter is the design and implementation of mine wall water system. With the help of Microsoft Visual Studio 2012 as the development environment and Visual Basic.NET as the development language, the emergency risk avoidance system is designed, and then based on the engineering geological materials of a mine, it is applied to the mine.
