【摘要】：隨著社會(huì)的不斷發(fā)展,煤炭對國家經(jīng)濟(jì)的影響越來越大,人們對煤炭生產(chǎn)過程中人身與財(cái)產(chǎn)安全的關(guān)注度也越來越高。我國作為產(chǎn)煤大國,煤炭在為國家?guī)砭薮蠼?jīng)濟(jì)利益的同時(shí),在煤炭生產(chǎn)過程中也會(huì)有瓦斯爆炸、煤與瓦斯突出等諸多危險(xiǎn)事故的發(fā)生,造成人身及財(cái)產(chǎn)傷害,其中煤與瓦斯突出事故發(fā)生的頻率不僅較多而且后果嚴(yán)重。所以,加強(qiáng)煤與瓦斯突出預(yù)警工作的研究,減少煤礦危險(xiǎn)事故發(fā)生具有重要的現(xiàn)實(shí)意義。本文首先介紹了煤與瓦斯突出預(yù)警國內(nèi)外發(fā)展現(xiàn)狀以及現(xiàn)有的可拓關(guān)聯(lián)函數(shù)研究成果,系統(tǒng)分析了二區(qū)間套下、二區(qū)域套下、三區(qū)間套下和三區(qū)域套下確定型初等關(guān)聯(lián)函數(shù)以及二區(qū)間套下、三區(qū)間套下不確定型初等關(guān)聯(lián)函數(shù)的基本理論、定理及構(gòu)造方法。其次,提出節(jié)域?yàn)樨?fù)無窮區(qū)間初等關(guān)聯(lián)函數(shù)、節(jié)域?yàn)檎裏o窮區(qū)間初等關(guān)聯(lián)函數(shù)、二區(qū)域套下不確定型初等關(guān)聯(lián)函數(shù)和三區(qū)域套下不確定型初等關(guān)聯(lián)函數(shù)的構(gòu)造方法,給出可拓距、可拓位值和初等關(guān)聯(lián)函數(shù)公式,得到相關(guān)定理并給出證明。然后通過篩選確定煤與瓦斯突出預(yù)警指標(biāo)體系,介紹了模糊層次分析法基本理論和權(quán)重計(jì)算公式,以三區(qū)域套下不確定型初等關(guān)聯(lián)函數(shù)公式和模糊層次分析法為基礎(chǔ),建立煤與瓦斯突出可拓預(yù)警模型,并給出模型應(yīng)用的具體步驟。最后以四老溝礦為實(shí)際背景,運(yùn)用文中所建立的可拓預(yù)警模型計(jì)算出四老溝礦煤與瓦斯突出預(yù)警的綜合關(guān)聯(lián)度,得出該礦煤與瓦斯突出預(yù)警級別為輕警的結(jié)論。上述研究不僅進(jìn)一步擴(kuò)展了可拓關(guān)聯(lián)函數(shù)的構(gòu)造方法,而且所建立的預(yù)警模型對礦井煤與瓦斯突出災(zāi)害事故的預(yù)防具有一定的參考價(jià)值。
[Abstract]:With the development of society, the influence of coal on national economy is more and more great, and people pay more and more attention to the safety of personal and property in the process of coal production. As a big coal-producing country, coal has brought huge economic benefits to the country, but in the process of coal production, there will also be gas explosion, coal and gas outburst and many other dangerous accidents, resulting in personal and property injury. The frequency of coal and gas outburst accidents is not only more and more serious consequences. Therefore, it is of great practical significance to strengthen the research of coal and gas outburst warning and to reduce the occurrence of dangerous accidents in coal mines. In this paper, the current situation of coal and gas outburst warning at home and abroad and the existing research results of extension correlation function are introduced in this paper. The basic theories, theorems and construction methods of the deterministic elementary correlation function under the three regions intercalation and the two regions intercalation and the three regions intercalation. Secondly, the method of constructing uncertain elementary correlation function with two regions and three regions with uncertainty is proposed, which is negative infinite interval elementary correlation function, positive infinite interval elementary correlation function in section domain, and positive infinite interval elementary correlation function in segment domain. The formulas of extension distance, extension value and elementary correlation function are given, and the correlation theorem is obtained and proved. Then, through screening and determining the early warning index system of coal and gas outburst, this paper introduces the basic theory of fuzzy analytic hierarchy process and the calculation formula of weight, which is based on the formula of uncertain elementary correlation function and fuzzy analytic hierarchy process under three regions. The extension warning model of coal and gas outburst is established, and the concrete steps of its application are given. Finally, based on the actual background of Silaogou Mine, the comprehensive correlation degree between coal and gas outburst early warning is calculated by using the extension early-warning model established in this paper, and the conclusion that the warning level of coal and gas outburst in this mine is light warning is obtained. The above research not only extends the construction method of extension correlation function, but also has certain reference value for the prevention of mine coal and gas outburst disaster accident.
