【摘要】：矿井通风系统(Mine Ventilation System-MVS)是由通风网络(包括通风网络中各条巷道及其风流、通风构筑物和各类用风场所)、通风动力及其附属装置、风流监测与控制设施等若干子系统及其单元组成的大型复杂关联系统(Large Complex Correlative System-LCCS)。矿井通风系统在矿井设计、建造、运行、管理等各个阶段对矿山的安全作业起着举足轻重。为了满足安全上可靠、技术上可行、经济上合理,需对矿井通风系统进行综合安全评价分析。 本文的研究是以《云南永昌铅锌股份有限公司勐糯铅锌矿井下通风系统优化设计研究》课题为基础而展开的,目的是通过对井下复杂通风系统组成部分的安全评价进行一些理论研究,达到对通风系统的调节作出正确的决策。矿井通风系统的复杂具体表现为系统的多环节性、非线性、时变性和可维修性以及系统各影响因素之间的强耦合性,其关联属性具有模糊性、灰色性和层次性。依据矿井通风系统的属性,在充分借鉴已有研究成果的基础上,做了如下深入研究： 1、综合评述国内外针对矿井通风系统安全评价的研究现状,阐述了国内外矿井通风安全评价研究方法及各种评价体系组成的特点。 2、详细的介绍了本文综合评价理论体系。通过综合运用层次分析法、灰色系统理论和模糊数学,提出了矿井通风系统的灰色评价与层次分析法及模糊数学相结合的灰色多层次综合评价模型。 3、按照现代系统安全理论和人—机—环境—管理分析方法,建立包括矿井通风系统环境B1、通风技术设施B2、技术工作人员B3、通风系统安全管理B4的4个一级单元、25项二级指标的多因素多级指标评价体系。 4、应用层次分析法确定矿井通风系统安全评价指标体系中各指标的权重,并运用灰色关联度分析函数,使灰关系量化、序化、显化,构造了灰色关联矩阵和综合评价矩阵,在此基础上利用模糊综合评价进行三级综合评价。该体系评价方法能很好地解决矿井通风中存在的大量内涵和外延都不明确的模糊概念,定性与定量的对井下通风系统作出评价,是一种简便而有效的评价与决策方法。 5、对永昌股份有限公司勐糯铅锌矿井下通风系统安全水平进行了全面科学评价,最后得出了矿井安全级别,与实际情况相吻合。 实例表明该种评价方法较客观的评价了矿井通风系统的优劣程度,定性与定量的指出组成通风系统各评价因素对影响矿井通风优劣情况的轻重缓急,为下提高通风效果提出决策依据,应用于工程实际,具有可行性及工程实用价值。
[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 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.

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.
