【摘要】:論文主要針對(duì)礦井突水的仿真過(guò)程進(jìn)行了研究。系統(tǒng)總結(jié)出了突水過(guò)程的相關(guān)規(guī)律。包括:突水點(diǎn)分布規(guī)律、突水過(guò)程演化規(guī)律、突水方式與突水漫延的規(guī)律、巷道內(nèi)水流運(yùn)動(dòng)規(guī)律。并介紹了影響突水的地質(zhì)和工程因素,作為后續(xù)建立突水仿真算法的理論基礎(chǔ)。 該研究采用巷道的測(cè)量導(dǎo)線點(diǎn)作為數(shù)據(jù)源,建立了巷道空間數(shù)據(jù)結(jié)構(gòu)和拓?fù)潢P(guān)系,分析巷道網(wǎng)絡(luò)聯(lián)通性和巷道網(wǎng)絡(luò)權(quán)值。并且對(duì)巷道的存儲(chǔ)結(jié)構(gòu)進(jìn)行了優(yōu)化,采用稀疏矩陣的存儲(chǔ)方式,提高算法的計(jì)算和存儲(chǔ)效率。 論文根據(jù)水害事故避災(zāi)線路的設(shè)計(jì)原則,建立了突水避災(zāi)算法。該算法在圖論學(xué)的基礎(chǔ)之上,通過(guò)對(duì)巷道的網(wǎng)絡(luò)可通行性進(jìn)行分析,實(shí)現(xiàn)了由多個(gè)任意起始點(diǎn)至多個(gè)任意終點(diǎn)的,多地點(diǎn)人員避災(zāi)的最佳線路算法。為礦井安全生產(chǎn)服務(wù)。 最后,研究并實(shí)現(xiàn)了突水漫延算法、水量約束突水漫延算法。該算法根據(jù)預(yù)計(jì)的突水總量、突水起始點(diǎn)、巷道斷面、坡度、長(zhǎng)度等情況,仿模擬水害在巷道內(nèi)的發(fā)展演化過(guò)程,模擬水流的下向漫延和上向升漲,,分析出突水影響的范圍。并求解出最佳的水害避災(zāi)路徑。 該算法實(shí)現(xiàn)了由突水量約束突水范圍的快速直觀三維表達(dá),為制定避災(zāi)路線,事故調(diào)查,優(yōu)化路線及應(yīng)急救援決策提供依據(jù)。
[Abstract]:The paper mainly studies the simulation process of mine water inrush.The related laws of water inrush are summarized systematically.It includes: the distribution law of water inrush point, the evolution law of water inrush process, the law of water inrush mode and water inrush spread, and the water flow movement law in roadway.The geological and engineering factors affecting water inrush are introduced as the theoretical basis for the subsequent establishment of water inrush simulation algorithm.In this study, the spatial data structure and topological relationship of roadway are established by using the measured traverse points of roadway as data source, and the network connectivity and weight of roadway network are analyzed.The storage structure of laneway is optimized and the storage efficiency of the algorithm is improved by using sparse matrix storage method.According to the design principle of water disaster avoidance line, the algorithm of water inrush disaster avoidance is established in this paper.On the basis of graph theory, the algorithm realizes the optimal route algorithm from multiple arbitrary starting points to multiple arbitrary endpoints by analyzing the network passability of laneway.For mine safety production services.Finally, the water inrush diffusion algorithm and the water-constrained water-inrush diffusion algorithm are studied and implemented.According to the predicted total water inrush, the starting point of water inrush, the section of roadway, slope, length and so on, this algorithm simulates the development and evolution process of water disaster in the roadway, simulates the downward spread and upward rise of water flow, and analyzes the influence range of water inrush.The optimal path of water hazard avoidance is obtained.The algorithm can express the range of water inrush by water inrush quickly and intuitively, and provide the basis for making disaster avoidance route, accident investigation, optimizing route and emergency rescue decision.
