【摘要】：礦井通風是礦井安全生產(chǎn)的命脈。為了認真貫徹落實“安全第一，預防為主”的方針，促進煤礦安全生產(chǎn)和管理，提高礦井安全保障能力及抗災能力，必須保證通風系統(tǒng)保持最佳運行狀態(tài)，近些年，一些國有重點煤礦隨著開采深度的加大，自然災害的威脅更加的突出，有不少煤礦的瓦斯涌出量增大，原來是低瓦斯礦井的變?yōu)楦咄咚沟V井或者有突出危險的礦井。礦井通風系統(tǒng)是整個煤炭企業(yè)生產(chǎn)大系統(tǒng)的命脈，它擔負著向各個用風地點輸送高質高量的新鮮空氣。雖為礦井開采系統(tǒng)服務，但是事關整個企業(yè)生產(chǎn)大系統(tǒng)的安全生產(chǎn)，縱觀歷年來的煤礦事故，尤其是重特大事故，常常是瓦斯積聚造成瓦斯局部爆炸引起的，這些都與礦井的通風系統(tǒng)有著直接或間接的關系,因此應該對煤礦的通風系統(tǒng)的安全可靠性進行評價。 本文首先根據(jù)礦井通風系統(tǒng)安全可靠性評價體系建立的原則，從主要礦井通風動力及設施可靠性、通風系統(tǒng)環(huán)境可靠性、礦井安全監(jiān)測系統(tǒng)可靠性、礦井通風防災救災系統(tǒng)可靠性4個方面建立了礦井通風系統(tǒng)安全可靠性評價體系，明確各評價指標的意義及計算方法，進行指標分級。介紹隸屬函數(shù)確定的原則、隸屬函數(shù)的構造方法及確定類型，詳細的給出每個評價指標的隸屬函數(shù)。運用插值法完善評價體系，利用插值法繪制出指標與其隸屬度之間的函數(shù)曲線，當評價指標為一具體數(shù)值時，則其將對應一個相對精確的隸屬度值。介紹了權重確定的基本理論及層次分析法，并提出改進的層次分析法，利用改進的層次分析法計算求出礦井通風系統(tǒng)安全可靠性評價體系準則層的權重及其各二級因素的權重，并給出評價結果的綜合處理。通過對模糊綜合評價方法在礦井通風系統(tǒng)安全可靠性評價中的應用的研究，說明模糊綜合評價方法應用于礦井通風系統(tǒng)安全可靠性評價中的可行性，闡述模糊綜合評價的一些基礎知識，并介紹多層次的模糊綜合評價以及模糊合成算子的選擇情況，，提出利用模糊綜合評判評價一些定性評價的因素，用統(tǒng)計學方法確定模糊綜合評價的隸屬度，引入二級模糊綜合評判評價礦井通風系統(tǒng)的安全可靠性的構想。
[Abstract]:Mine ventilation is the lifeblood of mine safety production. In order to implement the principle of "safety first and prevention first", to promote the safety production and management of coal mine, and to improve the ability of mine safety guarantee and disaster resistance, In recent years, with the increase of mining depth, the threat of natural disasters is more prominent in some state-owned key coal mines, and the amount of gas emission increases in many coal mines. The mine ventilation system is the lifeblood of the large production system of the whole coal enterprise. It is responsible for conveying high quality and high quantity of fresh air to various wind-using sites. Although it serves the mine mining system, it has a bearing on the safety production of the large production system of the whole enterprise. Throughout the years, coal mine accidents, especially serious and serious accidents, It is often caused by local gas explosion caused by gas accumulation, which is directly or indirectly related to mine ventilation system. Therefore, the safety and reliability of coal mine ventilation system should be evaluated. According to the principles of safety and reliability evaluation system of mine ventilation system, this paper firstly discusses the reliability of ventilation power and facilities, the environmental reliability of ventilation system, and the reliability of mine safety monitoring system. In this paper, the safety and reliability evaluation system of mine ventilation system is established in four aspects: the reliability of mine ventilation disaster prevention and disaster relief system, the significance and calculation method of each evaluation index, the classification of indexes, and the principle of determining membership function. The construction method and type of membership function are given in detail. The evaluation system is perfected by interpolation method, and the function curve between index and membership degree is drawn by interpolation method. When the evaluation index is a specific value, it will correspond to a relatively accurate membership value. The basic theory of weight determination and the analytic hierarchy process (AHP) are introduced, and an improved AHP is proposed. By using the improved analytic hierarchy process (AHP), the weight of the criterion layer of the safety and reliability evaluation system of mine ventilation system and the weight of the secondary factors are calculated. Through the research on the application of fuzzy comprehensive evaluation method in the safety and reliability evaluation of mine ventilation system, the comprehensive treatment of the evaluation results is given. The feasibility of applying the fuzzy comprehensive evaluation method to the safety and reliability evaluation of mine ventilation system is explained. Some basic knowledge of fuzzy comprehensive evaluation is expounded, and the multi-level fuzzy comprehensive evaluation and the selection of fuzzy composition operator are introduced. This paper puts forward the conception of evaluating the safety and reliability of mine ventilation system by using fuzzy comprehensive evaluation to evaluate some qualitative evaluation factors, determining the membership degree of fuzzy comprehensive evaluation by statistical method, and introducing the two-stage fuzzy comprehensive evaluation method to evaluate the safety and reliability of mine ventilation system.
