【摘要】：近年來國家對礦山的安全生產(chǎn)工作日益重視,但礦山災害事故還是時有發(fā)生。在礦山事故發(fā)生后,如何確定一條最佳的避災救援路線，指導受災人員安全撤離從而將事故的影響降到最低,就成為目前礦山緊急事故處理方法的重點研究對象。 目前對于礦山避災救援路線規(guī)劃的研究,主要側(cè)重于尋找“最短”路徑以及優(yōu)化路徑算法效率。大多數(shù)研究以“最短”路徑作為最優(yōu)路徑，一般僅考慮了巷道的長度、通行難易度等環(huán)境因素,而對巷道的安全性并沒有進行考慮。本文綜合考慮了巷道的環(huán)境因素和安全性兩個方面，對人員最優(yōu)逃生路徑進行了分析和研究。本文主要研究內(nèi)容如下： 1)分析了金屬礦山井下巷道的分布情況,根據(jù)其垂直方向上分層分布的特點,提出了對網(wǎng)絡(luò)圖進行分割處理的思想,以此來提高路經(jīng)算法搜索的效率。 2)分析了礦山井下巷道環(huán)境因素和幾種常見的重大災害的影響因素,并對這些因素的影響進行了量化處理。巷道的環(huán)境影響和安全性通過當量長度和健康損失度來進行衡量,并提出了兩個衡量權(quán)值的求解方法。 3)利用多目標優(yōu)化理論,提出了最優(yōu)路徑規(guī)劃決策模型。綜合考慮了路徑的當量長度和健康損失度進行最優(yōu)路徑的決策。 最后,在此研究基礎(chǔ)上,構(gòu)建了最優(yōu)路徑規(guī)劃原型系統(tǒng),并以凡口鉛鋅礦為應(yīng)用實例,對原型系統(tǒng)進行了應(yīng)用研究。圖28幅,表15個,參考文獻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.
