【摘要】:神華蒙西棋盤井煤礦緩坡副斜井井筒工程全長5 588 m,埋深476 m,呈螺旋狀至底部煤層工作面,井筒采用直墻半圓拱斷面,斷面尺寸18.9 m2。井筒通過地質(zhì)非常復(fù)雜,主要為第四系砂土層、第三系砂礫層、砂質(zhì)泥巖等,部分地段穿過煤層,加之井筒斷面小,施工難度非常大。為了實(shí)現(xiàn)斜井施工安全、快速、低成本的目標(biāo),本文在收集國內(nèi)外有關(guān)隧道和煤礦井巷施工技術(shù)資料的基礎(chǔ)上,結(jié)合棋盤井煤礦斜井的特點(diǎn),對(duì)斜井施工的技術(shù)難題進(jìn)行了研究。施工工法的確立和運(yùn)輸方案的選擇將直接影響斜井的施工進(jìn)度和施工安全,本文根據(jù)棋盤井斜井的斷面開挖形式,采用有軌運(yùn)輸施工技術(shù);研究了螺旋式斜井通風(fēng)技術(shù);研究了明槽段施工技術(shù);研究了第三系暗槽段施工技術(shù);研究了基巖段施工技術(shù)以及通風(fēng)施工技術(shù)。
[Abstract]:Shenhua Mengxi Qipan Coal Mine has a total length of 5 588 m and a buried depth of 476 m. The shaft adopts a straight wall semi-circular arch section with a sectional size of 18.9 m ~ 2. The wellbore passing through geology is very complicated, mainly composed of Quaternary sandy soil layer, Tertiary sandy gravel layer, sandy mudstone and so on. Some parts of the well pass through coal seam, and the shaft cross section is small, so the construction is very difficult. In order to achieve the goal of safe, fast and low cost construction of inclined wells, this paper combines the characteristics of inclined wells in Qipanjing coal mine on the basis of collecting the technical data of tunnel and coal mine roadway construction at home and abroad. The technical problems of inclined well construction are studied. The establishment of construction method and the choice of transportation scheme will directly affect the construction progress and construction safety of inclined well. According to the cross-section excavation form of chipboard well, the construction technology of rail transportation is adopted, and the ventilation technology of spiral inclined shaft is studied. The construction technology of the open groove section, the construction technology of the tertiary dark groove section, the construction technology of the bedrock section and the ventilation construction technology are studied.
