发布时间：2018-08-06 18:36
【摘要】：随着采矿业的发展,矿井建设规模越来越大,产量也随之提高。此时,传统的辅助运输模式已很难满足矿井安全、高效生产的要求,制约了矿井开采能力的提高,制约了矿井自动化和集中化控制的实现和发展。因此,对大型矿井迫切需要提高辅助运输的连续化和自动化水平。而要解决辅助运输系统连续化问题,需解决运输系统的贮运关系匹配、可靠性分配以及系统无人值守等若干关键技术问题。本文主要研究解决前两个关键技术问题,并为此做了如下几方面的研究:1、在研究分析矸石运输系统工艺流程的基础上,对工艺流程简化处理以及对辅助运输设备的输送能力进行等效转化,建立矸石运输系统的贮运基本模型,推导得出基本模型的贮运匹配关系方程。并进一步推广到更加一般的情况中,推导得出适用于求解任意子系统相关参数的一般匹配关系式。2、从所依据的基本原理、结构的组成部分以及各组成部分中相关数据矩阵所包含的元素值的是如何获取等方面介绍了在研究矸石运输系统可靠性分配时所用到的可靠性分配方法与模型——可靠性分配屋。3、以矸石运输系统为例,应用所建立的两个模型,计算得出矸石运输系统中各参数的理论值、实际值,以及基于故障模式计算得出可靠性分配指标,找出了系统中的薄弱环节。从而为设备的选型提供了一种新的参考方法,避免了设备选型的盲目性。同时,进一步提高了系统的可靠性。
[Abstract]:With the development of mining industry, the scale of mine construction is increasing, and the output is also increasing. At this time, the traditional auxiliary transportation mode has been difficult to meet the requirements of mine safety and efficient production, which restricts the improvement of mine mining capacity, and restricts the realization and development of mine automation and centralized control. Therefore, it is urgent to improve the continuous and automatic level of auxiliary transportation for large mines. In order to solve the continuous problem of auxiliary transportation system, it is necessary to solve some key technical problems such as transportation system storage and transportation relation matching, reliability distribution and system unattended. This paper mainly studies the first two key technical problems, and makes the following research on the following aspects: 1. On the basis of the research and analysis of the technological process of the gangue transportation system, The simplified technological process and equivalent transformation of transportation capacity of auxiliary transportation equipment were carried out, and the basic model of storage and transportation of gangue transportation system was established, and the equation of matching relation between storage and transportation of the basic model was derived. And further extended to the more general case, the general matching relation. 2, which is suitable for solving the relevant parameters of any subsystem, is derived from the basic principle. This paper introduces the reliability distribution methods and models used in the study of the reliability distribution of gangue transportation system from the aspects of the components of the structure and how to obtain the values of the elements contained in the relevant data matrix of each component. -Reliability Distribution House. 3, in the case of gangue transport systems, By using the two models established, the theoretical and practical values of the parameters in the gangue transportation system are calculated, as well as the reliability distribution index calculated based on the fault mode, and the weak links in the system are found out. It provides a new reference method for equipment selection and avoids blindness of equipment selection. At the same time, the reliability of the system is further improved.
