【摘要】：礦井通風(fēng)系統(tǒng)(Mine Ventilation System-MVS)是由通風(fēng)網(wǎng)絡(luò)(包括通風(fēng)網(wǎng)絡(luò)中各條巷道及其風(fēng)流、通風(fēng)構(gòu)筑物和各類用風(fēng)場所)、通風(fēng)動力及其附屬裝置、風(fēng)流監(jiān)測與控制設(shè)施等若干子系統(tǒng)及其單元組成的大型復(fù)雜關(guān)聯(lián)系統(tǒng)(Large Complex Correlative System-LCCS)。礦井通風(fēng)系統(tǒng)在礦井設(shè)計、建造、運行、管理等各個階段對礦山的安全作業(yè)起著舉足輕重。為了滿足安全上可靠、技術(shù)上可行、經(jīng)濟(jì)上合理,需對礦井通風(fēng)系統(tǒng)進(jìn)行綜合安全評價分析。 本文的研究是以《云南永昌鉛鋅股份有限公司勐糯鉛鋅礦井下通風(fēng)系統(tǒng)優(yōu)化設(shè)計研究》課題為基礎(chǔ)而展開的,目的是通過對井下復(fù)雜通風(fēng)系統(tǒng)組成部分的安全評價進(jìn)行一些理論研究,達(dá)到對通風(fēng)系統(tǒng)的調(diào)節(jié)作出正確的決策。礦井通風(fēng)系統(tǒng)的復(fù)雜具體表現(xiàn)為系統(tǒng)的多環(huán)節(jié)性、非線性、時變性和可維修性以及系統(tǒng)各影響因素之間的強耦合性,其關(guān)聯(lián)屬性具有模糊性、灰色性和層次性。依據(jù)礦井通風(fēng)系統(tǒng)的屬性,在充分借鑒已有研究成果的基礎(chǔ)上,做了如下深入研究： 1、綜合評述國內(nèi)外針對礦井通風(fēng)系統(tǒng)安全評價的研究現(xiàn)狀,闡述了國內(nèi)外礦井通風(fēng)安全評價研究方法及各種評價體系組成的特點。 2、詳細(xì)的介紹了本文綜合評價理論體系。通過綜合運用層次分析法、灰色系統(tǒng)理論和模糊數(shù)學(xué),提出了礦井通風(fēng)系統(tǒng)的灰色評價與層次分析法及模糊數(shù)學(xué)相結(jié)合的灰色多層次綜合評價模型。 3、按照現(xiàn)代系統(tǒng)安全理論和人—機—環(huán)境—管理分析方法,建立包括礦井通風(fēng)系統(tǒng)環(huán)境B1、通風(fēng)技術(shù)設(shè)施B2、技術(shù)工作人員B3、通風(fēng)系統(tǒng)安全管理B4的4個一級單元、25項二級指標(biāo)的多因素多級指標(biāo)評價體系。 4、應(yīng)用層次分析法確定礦井通風(fēng)系統(tǒng)安全評價指標(biāo)體系中各指標(biāo)的權(quán)重,并運用灰色關(guān)聯(lián)度分析函數(shù),使灰關(guān)系量化、序化、顯化,構(gòu)造了灰色關(guān)聯(lián)矩陣和綜合評價矩陣,在此基礎(chǔ)上利用模糊綜合評價進(jìn)行三級綜合評價。該體系評價方法能很好地解決礦井通風(fēng)中存在的大量內(nèi)涵和外延都不明確的模糊概念,定性與定量的對井下通風(fēng)系統(tǒng)作出評價,是一種簡便而有效的評價與決策方法。 5、對永昌股份有限公司勐糯鉛鋅礦井下通風(fēng)系統(tǒng)安全水平進(jìn)行了全面科學(xué)評價,最后得出了礦井安全級別,與實際情況相吻合。 實例表明該種評價方法較客觀的評價了礦井通風(fēng)系統(tǒng)的優(yōu)劣程度,定性與定量的指出組成通風(fēng)系統(tǒng)各評價因素對影響礦井通風(fēng)優(yōu)劣情況的輕重緩急,為下提高通風(fēng)效果提出決策依據(jù),應(yīng)用于工程實際,具有可行性及工程實用價值。
[Abstract]:The mine ventilation system (Mine Ventilation System-MVS) is composed of ventilation networks (including roadways and their air flow in the ventilation network, ventilation structures and all kinds of air places), ventilation power and its accessories, Air flow monitoring and control facilities and other subsystems and their units composed of a large complex correlation system (Large Complex Correlative System-LCCS). Mine ventilation system plays an important role in mine design, construction, operation and management. In order to meet the needs of safety reliability, technical feasibility and economic reasonableness, it is necessary to conduct comprehensive safety evaluation and analysis of mine ventilation system. The research of this paper is based on the research on the optimization design of ventilation system in Mengnuo lead-zinc mine of Yunnan Yongchang lead and Zinc Co., Ltd. The purpose of this paper is to make a correct decision on the regulation of the ventilation system through some theoretical research on the safety evaluation of the components of the underground complex ventilation system. The complexity of mine ventilation system is characterized by its multi-links, nonlinearity, time-variability and maintainability, and the strong coupling among the influencing factors of the system. The associated properties of the system are fuzzy, grey and hierarchical. Based on the attributes of mine ventilation system and based on the existing research results, this paper makes the following in-depth research: 1. The current research situation of mine ventilation system safety evaluation at home and abroad is comprehensively reviewed. The research methods of mine ventilation safety evaluation at home and abroad and the characteristics of various evaluation systems are described. 2. The comprehensive evaluation theory system of this paper is introduced in detail. By using the analytic hierarchy process (AHP), grey system theory and fuzzy mathematics, a grey multi-level comprehensive evaluation model of mine ventilation system is put forward, which combines the grey evaluation with the analytic hierarchy process (AHP) and the fuzzy mathematics. 3. According to modern system safety theory and man-machine-environment-management analysis method, four primary units, including mine ventilation system environment B1, ventilation technical facility B2, technical staff B3, ventilation system safety management B4, are established. Multi-factor and multilevel index evaluation system of 25 secondary indexes. 4. The weight of each index in the safety evaluation index system of mine ventilation system is determined by the analytic hierarchy process (AHP), and the grey relation is quantified, sequenced and explicit by using the grey relational degree analysis function, and the grey relation matrix and the comprehensive evaluation matrix are constructed. On this basis, fuzzy comprehensive evaluation is used to carry out three-level comprehensive evaluation. The evaluation method of this system can solve the fuzzy concept of a large number of intension and extension which are not clear in mine ventilation. It is a simple and effective method to evaluate the underground ventilation system qualitatively and quantitatively. 5. The safety level of ventilation system under Mengnuo lead-zinc mine of Yongchang Co., Ltd is evaluated scientifically. Finally, the safety grade of mine is obtained, which is consistent with the actual situation. The example shows that the evaluation method objectively evaluates the quality of mine ventilation system, and points out qualitatively and quantitatively that the evaluation factors that constitute ventilation system have an important effect on the quality of mine ventilation. In order to improve the ventilation effect, the decision basis is put forward and applied to engineering practice, which is feasible and practical.
