【摘要】：井工煤礦通風(fēng)系統(tǒng)與礦井的安全、高效有著緊密的聯(lián)系,很大程度上,瓦斯治理效果的好壞取決于風(fēng)流對(duì)工作面等用風(fēng)位置的有效覆蓋。所以,煤礦通風(fēng)系統(tǒng)的優(yōu)化研究勢(shì)在必行,不僅提高和改善了礦井生產(chǎn)上多方面的效益,還使得井下各崗位操作人員的人身健康與安全得到了保證。關(guān)于礦井通風(fēng)系統(tǒng)的改造不是簡(jiǎn)單的選擇問(wèn)題,它是由眾多定量及定性的因素組成的系統(tǒng)性決策問(wèn)題。論文以汪洋煤礦作為研究背景,通過(guò)對(duì)大量相關(guān)文獻(xiàn)的閱讀和學(xué)習(xí),在分析礦井通風(fēng)系統(tǒng)現(xiàn)狀的基礎(chǔ)上,結(jié)合長(zhǎng)遠(yuǎn)規(guī)劃需求,擬定出三種可行的、較為合理的改造方案:更換主要通風(fēng)機(jī)、二進(jìn)一回通風(fēng)方式、建立礦井瓦斯抽采系統(tǒng)后的一進(jìn)二回通風(fēng)方式。以符合國(guó)家技術(shù)標(biāo)準(zhǔn)規(guī)范、實(shí)現(xiàn)礦井通風(fēng)阻力-通風(fēng)風(fēng)量匹配為優(yōu)化目標(biāo),采用礦井通風(fēng)輔助決策系統(tǒng)MVAD對(duì)三種礦井通風(fēng)系統(tǒng)改造方案進(jìn)行解算決策,從滿(mǎn)足國(guó)家技術(shù)標(biāo)準(zhǔn)規(guī)范、實(shí)現(xiàn)礦井通風(fēng)阻力-通風(fēng)風(fēng)量匹配上綜合分析比較,從定性、定量方面決策了建立礦井瓦斯抽采系統(tǒng)后的一進(jìn)二回通風(fēng)方式改造方案是汪洋煤礦通風(fēng)系統(tǒng)改造的優(yōu)化方案:1#回風(fēng)井安設(shè)兩臺(tái)型號(hào)為FBCDZ-№14D型,電機(jī)功率2×55kW;2#回風(fēng)井安設(shè)兩臺(tái)型號(hào)為FBCDZ-№14B型,電機(jī)功率2×30kW。汪洋煤礦通風(fēng)系統(tǒng)改造優(yōu)化方案實(shí)施后,通風(fēng)系統(tǒng)滿(mǎn)足了國(guó)家技術(shù)標(biāo)準(zhǔn)規(guī)范的要求,礦井通風(fēng)阻力降低了71.91%,達(dá)到了礦井通風(fēng)系統(tǒng)風(fēng)網(wǎng)匹配的目的;實(shí)現(xiàn)了礦井通風(fēng)通風(fēng)容易,礦井主要通風(fēng)機(jī)配套電機(jī)功率降低了34.62%,每年節(jié)約電費(fèi)65萬(wàn)元。汪洋煤礦礦井通風(fēng)系統(tǒng)改造途徑的研究說(shuō)明,礦井通風(fēng)系統(tǒng)改造方案是將礦井通風(fēng)系統(tǒng)改造與建立礦井瓦斯抽采系統(tǒng)等相結(jié)合的綜合性?xún)?yōu)化決策問(wèn)題。汪洋煤礦礦井通風(fēng)系統(tǒng)改造成功,為生產(chǎn)礦井的通風(fēng)系統(tǒng)改造提供了可以借鑒的經(jīng)驗(yàn)。
[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.
