【摘要】：近年来国家对矿山的安全生产工作日益重视,但矿山灾害事故还是时有发生。在矿山事故发生后,如何确定一条最佳的避灾救援路线，指导受灾人员安全撤离从而将事故的影响降到最低,就成为目前矿山紧急事故处理方法的重点研究对象。目前对于矿山避灾救援路线规划的研究,主要侧重于寻找“最短”路径以及优化路径算法效率。大多数研究以“最短”路径作为最优路径，一般仅考虑了巷道的长度、通行难易度等环境因素,而对巷道的安全性并没有进行考虑。本文综合考虑了巷道的环境因素和安全性两个方面，对人员最优逃生路径进行了分析和研究。本文主要研究内容如下： 1)分析了金属矿山井下巷道的分布情况,根据其垂直方向上分层分布的特点,提出了对网络图进行分割处理的思想,以此来提高路经算法搜索的效率。 2)分析了矿山井下巷道环境因素和几种常见的重大灾害的影响因素,并对这些因素的影响进行了量化处理。巷道的环境影响和安全性通过当量长度和健康损失度来进行衡量,并提出了两个衡量权值的求解方法。 3)利用多目标优化理论,提出了最优路径规划决策模型。综合考虑了路径的当量长度和健康损失度进行最优路径的决策。最后,在此研究基础上,构建了最优路径规划原型系统,并以凡口铅锌矿为应用实例,对原型系统进行了应用研究。图28幅,表15个,参考文献66篇。
[Abstract]:In recent years, the state pays more and more attention to the safety of mine production, but the mine disaster accidents still occur from time to time. After the mine accident, how to determine the best route of disaster avoidance and rescue, to guide the disaster personnel to evacuate safely, so as to minimize the impact of the accident, has become the key research object of the mine emergency treatment methods at present. At present, the research on route planning of mine disaster avoidance and rescue mainly focuses on finding the shortest path and optimizing the efficiency of path algorithm. Most studies take the shortest path as the optimal path, and generally only consider the environmental factors such as the length of the roadway, the ease of passage and so on, but the safety of the roadway is not taken into account. In this paper, the environmental factors and safety of the tunnel are considered, and the optimal escape path of personnel is analyzed and studied. The main contents of this paper are as follows: 1) the distribution of underground roadway in metal mine is analyzed. According to the characteristics of layered distribution in vertical direction, the idea of segmenting the network map is put forward. In order to improve the efficiency of the algorithm search. 2) the environmental factors of underground roadway and some common major disasters are analyzed, and the effects of these factors are quantitatively dealt with. The environmental impact and safety of the roadway are measured by the equivalent length and the health loss degree, and two methods to calculate the weight value are put forward. 3) based on the theory of multi-objective optimization, an optimal path planning decision model is proposed. The optimal path decision is made by considering the equivalent length of the path and the degree of health loss. Finally, on the basis of this research, the optimal path planning prototype system is constructed, and the application of the prototype system is studied with Fankou lead-zinc mine as an example.
