【摘要】：礦井通風(fēng)系統(tǒng)是礦井生產(chǎn)的重要系統(tǒng)之一，對(duì)井下災(zāi)害治理和預(yù)防發(fā)揮著巨大作用。通風(fēng)系統(tǒng)優(yōu)化是保障礦井安全高效生產(chǎn)的有力手段，優(yōu)化后的通風(fēng)系統(tǒng)在節(jié)能、抗災(zāi)變能力等方面有很大提高，進(jìn)而為礦山企業(yè)創(chuàng)造更大的經(jīng)濟(jì)效益。 本論文以平煤十三礦礦井通風(fēng)系統(tǒng)為研究對(duì)象，采用了理論分析與計(jì)算機(jī)解算通風(fēng)網(wǎng)絡(luò)的綜合研究方法，進(jìn)行了礦井通風(fēng)參數(shù)的收集、通風(fēng)阻力的測(cè)定、通風(fēng)優(yōu)化方案的提出及優(yōu)選、各優(yōu)選方案通風(fēng)網(wǎng)絡(luò)的解算、通風(fēng)網(wǎng)絡(luò)圖的繪制以及最優(yōu)通風(fēng)方案的確定等研究。依據(jù)通風(fēng)系統(tǒng)現(xiàn)狀所存在的問(wèn)題，提出了四個(gè)優(yōu)化方案，從各方案的技術(shù)、安全和經(jīng)濟(jì)角度進(jìn)行了詳細(xì)論述和對(duì)比。 本論文采用3D Vent通風(fēng)管理軟件對(duì)東翼通風(fēng)系統(tǒng)和經(jīng)方案三、方案四改造后的通風(fēng)系統(tǒng)進(jìn)行了通風(fēng)網(wǎng)絡(luò)解算，且東翼通風(fēng)系統(tǒng)各巷道風(fēng)量解算結(jié)果的相對(duì)誤差均低于10%，從而證明了所建立的通風(fēng)巷道模型可用于通風(fēng)系統(tǒng)的分析，可在此基礎(chǔ)上進(jìn)行通風(fēng)系統(tǒng)優(yōu)化探究。通過(guò)對(duì)方案三、方案四的技術(shù)可行性、安全可靠性、經(jīng)濟(jì)合理性等指標(biāo)的討論和對(duì)比，最終選擇了方案四。計(jì)算機(jī)解算結(jié)果表明經(jīng)方案四優(yōu)化改造后的東翼通風(fēng)系統(tǒng)總回風(fēng)量可增加105m3/s，東回風(fēng)井主扇負(fù)壓由3881Pa降到2380Pa，風(fēng)量由179m3/s降到了154.5m3/s；-200回風(fēng)井新增加主扇負(fù)壓為1788Pa，風(fēng)量為129.5m3/s，主要進(jìn)、回風(fēng)巷及各個(gè)用風(fēng)地點(diǎn)風(fēng)量充足且未出現(xiàn)風(fēng)速超限的情況。經(jīng)方案四改造后的通風(fēng)系統(tǒng)可實(shí)現(xiàn)己一采區(qū)、己一輔助采區(qū)、己三采區(qū)分區(qū)獨(dú)立通風(fēng)，消除了東翼通風(fēng)系統(tǒng)各采區(qū)間的角聯(lián)通風(fēng)問(wèn)題，提高了東翼通風(fēng)系統(tǒng)的穩(wěn)定性。經(jīng)方案四改造后東翼通風(fēng)系統(tǒng)的主扇電機(jī)總運(yùn)行功率由原來(lái)的908.1Kw降為811.55Kw，，一年可節(jié)約67.66萬(wàn)元電費(fèi)，給該礦帶來(lái)了一定的經(jīng)濟(jì)效益。 由此可見(jiàn)，方案四改造后的通風(fēng)系統(tǒng)可解決平煤十三礦東翼通風(fēng)系統(tǒng)風(fēng)量不足、通風(fēng)負(fù)壓過(guò)大等問(wèn)題，為礦井瓦斯災(zāi)害治理、高地溫災(zāi)害防治等工作打下堅(jiān)實(shí)的基礎(chǔ)，符合該礦長(zhǎng)遠(yuǎn)規(guī)劃要求。本課題的技術(shù)探究為平煤十三礦東翼通風(fēng)系統(tǒng)優(yōu)化改造提供了科學(xué)依據(jù)，其研究?jī)?nèi)容具有一定的理論意義和實(shí)用價(jià)值。
[Abstract]:Mine ventilation system is one of the important systems in mine production, which plays an important role in disaster control and prevention. Ventilation system optimization is a powerful means to ensure mine safety and high efficiency production. The optimized ventilation system has greatly improved in energy saving and disaster resistance, thus creating greater economic benefits for mining enterprises. This paper takes the ventilation system of coal mine in No. 13 coal mine as the research object, adopts the comprehensive research method of theoretical analysis and computer calculation of ventilation network, and carries on the collection of mine ventilation parameters and the determination of ventilation resistance. The research on the proposal and selection of ventilation optimization scheme, the solution of ventilation network, the drawing of ventilation network diagram and the determination of optimal ventilation scheme etc. According to the existing problems of ventilation system, four optimization schemes are put forward. The technical, safety and economic aspects of each scheme are discussed and compared in detail. In this paper, 3D vent ventilation management software is used to calculate the ventilation network of the east wing ventilation system and the ventilation system after scheme 3 and scheme 4. And the relative error of the air volume calculation results of each roadway in the east wing ventilation system is lower than 10, which proves that the established ventilation tunnel model can be used in the analysis of ventilation system, and on this basis, the ventilation system optimization can be explored. Through the discussion and comparison of the technical feasibility, safety and reliability, economic rationality and so on, the fourth scheme is selected. The results of computer calculation show that the total return air volume of the east wing ventilation system can be increased by 105 m3 / s, the negative pressure of the main fan of the east return shaft decreases from 3881 Pa to 2 380 Pa, and the air volume decreases from 179m3/s to 154.5 m 3 / s -200 return air well with a new increase in the negative pressure of the main fan to 1788 Pa. the air volume is 129.5 m3 / s. There is sufficient air volume and no excess wind speed in the return-air lane and each wind-using area. The ventilation system can be ventilated independently in the first mining area, the auxiliary mining area and the third mining area after the fourth scheme, which eliminates the angle connecting wind problem in each section of the eastern wing ventilation system, and improves the stability of the eastern wing ventilation system. The total operating power of the main fan motor of the east wing ventilation system was reduced from 908.1 KW to 811.55 Kw. after the fourth scheme, the electricity cost of 676600 yuan per year could be saved, which brought certain economic benefits to the mine. It can be seen from this that the ventilation system after scheme four can solve the problems of insufficient air volume and excessive negative pressure of ventilation system in the east wing of No. 13 Coal Mine, thus laying a solid foundation for mine gas disaster management and prevention and control of high ground temperature disasters. In line with the long-term planning requirements of the mine. The technical exploration of this subject provides a scientific basis for the optimization and transformation of ventilation system in the east wing of Pingshan No. 13 Coal Mine, and its research content has certain theoretical significance and practical value.
