【摘要】：火災(zāi)、煤塵、沖擊地壓和瓦斯爆炸等危險(xiǎn)是礦井常見(jiàn)災(zāi)害，一旦發(fā)生，災(zāi)害區(qū)域擴(kuò)展快，影響范圍大，直接威脅礦井及其井下工作人員的生命安全，為防止災(zāi)害的擴(kuò)大，減少損失，保障救援人員的生命安全，需要快速有效的建立起密閉隔離墻隔將易自燃區(qū)、有害氣體源或瓦斯聚集區(qū)進(jìn)行隔離。因此，研究礦山救護(hù)用快速密閉技術(shù)是礦山救援工作中亟待解決的一個(gè)重要課題。 論文在分析不同快速密閉的類型適應(yīng)性基礎(chǔ)上，研究了以氣囊式密閉和水凝膠防爆密閉相結(jié)合的礦用快速密閉技術(shù)體系。首先，分析了水凝膠密閉填充材料的成膠工藝與成膠機(jī)理，提出水凝膠填充材料制備方法，實(shí)驗(yàn)研究了水凝膠填充材料的膠凝時(shí)間，，包括不同影響因素下膠凝時(shí)間的變化規(guī)律以及水凝膠材料最適宜濃度及膠凝時(shí)間，掌握了水凝膠材料的穩(wěn)定性及力學(xué)性能。然后，選取了快速氣囊密閉材料，測(cè)試了材料的阻燃性，同時(shí)，對(duì)不同形狀巷道的適應(yīng)性及結(jié)構(gòu)設(shè)計(jì)進(jìn)行分析，確定了氣囊密閉的固定與充氣方式。最后，通過(guò)在模擬巷道對(duì)不同的巷道密閉進(jìn)行試驗(yàn)，實(shí)現(xiàn)了快速密閉的遠(yuǎn)距離安全施工，在大佛封煤礦和小南溝煤礦火災(zāi)救援應(yīng)用表明，為火區(qū)快速隔離及救援起到很重要的作用。 論文通過(guò)研究進(jìn)一步完善了礦山救護(hù)用快速密閉體系，為防止災(zāi)害的擴(kuò)大、減少損失、保障救護(hù)人員的生命安全，創(chuàng)造安全的救援環(huán)境提供了保障，對(duì)增強(qiáng)礦井的防災(zāi)、抗災(zāi)能力，保證了礦工的生命安全有重要意義。
[Abstract]:Fire, coal dust, impact ground pressure and gas explosion are common disasters in mines. Once they occur, the disaster areas expand rapidly and have a wide range of impacts, which directly threaten the safety of mine and underground workers, and prevent the expansion of disasters. In order to reduce losses and ensure the safety of rescue workers, it is necessary to quickly and effectively set up a closed wall to separate areas that are prone to spontaneous combustion, harmful gas sources or gas accumulation areas. Therefore, it is an important task to solve the problem in mine rescue work to study the fast sealing technology for mine rescue. On the basis of analyzing the adaptability of different types of rapid sealing, the paper studies the technical system of mine rapid sealing combined with airbag sealing and hydrogel explosion proof sealing. Firstly, the gelation process and gelling mechanism of the hydrogel sealing filling material were analyzed, and the preparation method of the hydrogel filling material was put forward, and the gelation time of the hydrogel filling material was studied experimentally. The stability and mechanical properties of the hydrogel materials were mastered, including the change of gelation time under different factors, the optimum concentration of hydrogel materials and the gelation time. Then, the fast airbag sealing material is selected, the flame retardancy of the material is tested, and the adaptability and structure design of different shape roadways are analyzed, and the fixed and inflatable ways of airbag sealing are determined. Finally, through the experiment of different tunnel airtight in simulated roadway, the long distance safety construction of fast airtight is realized. The application of fire rescue in Dafofeng coal mine and Xiaonangou coal mine shows that, It plays an important role in fast isolation and rescue of fire area. Through the research, the paper further consummates the fast airtight system of mine rescue, which can prevent the expansion of disaster, reduce the loss, guarantee the life safety of rescuers, create a safe rescue environment, and enhance mine disaster prevention. The ability to resist disasters is of great significance to ensure the safety of miners.
