【摘要】：煤矿资源在我国能源的提供中一直占据着重要位置,煤炭行业的发展一直受到国家的高度重视。近年来,随着高产高效矿井的快速建设和“科技强企”战略的实施,智能化工作面逐渐成为采煤领域研究的热点课题。当前智能化工作面作为推进矿井建设走向自动化、信息化的重要方式,具有安全性高,科技含量高的优点。智能化工作面的建立,可以有效提升煤炭企业的核心竞争力,切实提高矿井生产水平,真正实现煤矿的减人提效。智能化工作面系统构建及可靠性评价研究是近年来的研究热点。为了解决智能化矿井在建设中存在的系统划分不明确,工作面在快速连续推进过程中出现各系统协同工作中出现的不可靠等问题,本论文研究了智能化工作面系统构建和可靠性评价分析。本文首先建立了智能化工作面系统模型,包括顺槽集中控制中心、采煤机智能控制系统、支架围岩电液控制系统、工作面视频监控系统、通讯网络系统、智能负荷中心系统和智能集成供液系统。这7个子系统具有连接紧密、相互协同运行的特点。本文在分析了各系统的构成及功能的基础上,提出了智能化工作面系统的评价指标。由于智能化矿井在实施过程中的可靠程度本身具有模糊性的特点,本文提出了基于多层次模糊分析的可靠性评价方法,对智能化矿井建设可靠度进行评价。该方法是通过对建立的智能化工作面模型进行分析,得出智能化工作面在建设中各个指标的权重值,为智能化工作面可靠性评价水平的发展提供理论支持。最后,本文结合山西焦煤集团晋兴公司斜沟矿18201智能化工作面,分析了该矿智能化工作面系统,并对该系统的可靠性进行了基于多层次模糊分析的可靠性评价。结果表明:该方法可以较好的对该矿智能化工作建设的可靠性进行评价,具有一定的实践指导意义。
[Abstract]:Coal resources have always occupied an important position in the supply of energy in China, and the development of coal industry has been attached great importance to by the country. In recent years, with the rapid construction of high-yield and high-efficiency mines and the implementation of the strategy of "strong enterprise in science and technology", intelligent working face has gradually become a hot topic in the field of coal mining. As an important way to promote the automation and informatization of mine construction, intelligent working face has the advantages of high security and high science and technology content. The establishment of intelligent working face can effectively enhance the core competitiveness of coal enterprises, improve the level of mine production, and realize the reduction of human resources in coal mines. Intelligent working face system construction and reliability evaluation is a hot research topic in recent years. In order to solve the problem that the system division is not clear in the construction of intelligent mine and the unreliability of each system in the process of rapid and continuous advance, etc. This paper studies the intelligent working face system construction and reliability evaluation analysis. In this paper, the intelligent working face system model is established, including the centralized control center along the channel, the intelligent control system of the shearer, the electro-hydraulic control system of the surrounding rock of the support, the video monitoring system of the working face and the communication network system. Intelligent load center system and intelligent integrated liquid supply system. These seven subsystems have the characteristics of close connection and cooperative operation. On the basis of analyzing the constitution and function of each system, the evaluation index of intelligent working face system is put forward in this paper. Because the reliability of intelligent mine in the process of implementation has the characteristic of fuzziness, the reliability evaluation method based on multi-level fuzzy analysis is put forward in this paper, and the reliability of intelligent mine construction is evaluated. This method is based on the analysis of the established intelligent working face model, and obtains the weight value of each index in the construction of the intelligent working face, which provides theoretical support for the development of the reliability evaluation level of the intelligent working face. Finally, this paper analyzes the intelligent working face system of 18201 intelligent working face of Shanxi Coking Coal Group Jinxing Company, and evaluates the reliability of the system based on multi-level fuzzy analysis. The results show that this method can evaluate the reliability of the intelligent work construction of the mine, and has certain practical significance.
