【摘要】：井工煤矿通风系统与矿井的安全、高效有着紧密的联系,很大程度上,瓦斯治理效果的好坏取决于风流对工作面等用风位置的有效覆盖。所以,煤矿通风系统的优化研究势在必行,不仅提高和改善了矿井生产上多方面的效益,还使得井下各岗位操作人员的人身健康与安全得到了保证。关于矿井通风系统的改造不是简单的选择问题,它是由众多定量及定性的因素组成的系统性决策问题。论文以汪洋煤矿作为研究背景,通过对大量相关文献的阅读和学习,在分析矿井通风系统现状的基础上,结合长远规划需求,拟定出三种可行的、较为合理的改造方案:更换主要通风机、二进一回通风方式、建立矿井瓦斯抽采系统后的一进二回通风方式。以符合国家技术标准规范、实现矿井通风阻力-通风风量匹配为优化目标,采用矿井通风辅助决策系统MVAD对三种矿井通风系统改造方案进行解算决策,从满足国家技术标准规范、实现矿井通风阻力-通风风量匹配上综合分析比较,从定性、定量方面决策了建立矿井瓦斯抽采系统后的一进二回通风方式改造方案是汪洋煤矿通风系统改造的优化方案:1#回风井安设两台型号为FBCDZ-№14D型,电机功率2×55kW;2#回风井安设两台型号为FBCDZ-№14B型,电机功率2×30kW。汪洋煤矿通风系统改造优化方案实施后,通风系统满足了国家技术标准规范的要求,矿井通风阻力降低了71.91%,达到了矿井通风系统风网匹配的目的;实现了矿井通风通风容易,矿井主要通风机配套电机功率降低了34.62%,每年节约电费65万元。汪洋煤矿矿井通风系统改造途径的研究说明,矿井通风系统改造方案是将矿井通风系统改造与建立矿井瓦斯抽采系统等相结合的综合性优化决策问题。汪洋煤矿矿井通风系统改造成功,为生产矿井的通风系统改造提供了可以借鉴的经验。
[Abstract]:The ventilation system of coal mine is closely related to the safety and efficiency of the mine. To a great extent, the effect of gas control depends on the effective coverage of the air flow on the position of the working face and so on. Therefore, it is imperative to study the optimization of coal mine ventilation system. It not only improves and improves the efficiency of mine production, but also ensures the health and safety of operators. The transformation of mine ventilation system is not a simple choice problem, it is a systematic decision problem composed of many quantitative and qualitative factors. This paper takes Wang Yang coal mine as the research background, through reading and studying a large number of related documents, on the basis of analyzing the present situation of mine ventilation system, combining the long-term planning demand, draw up three kinds of feasible, The more reasonable scheme is to replace the main ventilator, to establish the primary ventilation mode after the gas extraction system. In order to meet the national technical standard and realize the matching of mine ventilation resistance and ventilation air volume, the mine ventilation auxiliary decision system (MVAD) is adopted to solve the problem of three mine ventilation system reconstruction schemes. From the comprehensive analysis and comparison of meeting the national technical standards and specifications and realizing the matching of mine ventilation resistance and ventilation air volume, from the qualitative analysis, In quantitative terms, it is determined that the improvement scheme of the primary and secondary ventilation system after the establishment of the gas drainage system in the mine is the optimization scheme of the ventilation system transformation of Wang Yang coal mine. Two models of the return air shaft installed in the Wang Yang coal mine are FBCDZ-14D. The power of the motor is 2 脳 55kW / L and 2 脳 30kW respectively. The two models are FBCDZ- 14B and the motor power is 2 脳 30kW. After the implementation of the Wang Yang coal mine ventilation system reform optimization scheme, the ventilation system meets the requirements of the national technical standards and specifications, the mine ventilation resistance is reduced by 71.91, the purpose of the mine ventilation system ventilation network matching is achieved, and the mine ventilation is easy to be realized. The auxiliary motor power of mine main ventilator has been reduced 34.62, saving 650000 yuan per year. The study of Wang Yang mine ventilation system reconstruction shows that the mine ventilation system reform scheme is a comprehensive optimization decision problem which combines the mine ventilation system transformation with the establishment of mine gas drainage system. Wang Yang coal mine ventilation system reform successfully, for production mine ventilation system transformation can be used for reference experience.
