随着大同煤矿侏罗纪煤层的资源逐步枯竭,开采石炭系煤层迫在眉睫,各个老矿井正逐步准备延深开采石炭系煤层,对缩短延深工期,加快立井建设极为重要。为此,应针对反井技术延深立井进行研究。描述了同煤口泉沟矿的工程延伸概况,根据实际情况制定了具体的施工方案,通过对方案的详细比较,最终选定了最合适的方案。介绍了延深施工准备、施工工艺和施工工艺,为反井技术在延深立井中的应用提供了一定的理论依据,给日后类似工程的顺利开展提供了良好的借鉴。 With the gradual depletion of resources in the Datong Coal Mine Jurassic coal seam, it is imminent to exploit the Carboniferous coal seams. All the old mines are gradually preparing for the further exploration of the Carboniferous coal seams, which is extremely important for shortening the project duration and speeding up the construction of the shaft. To this end, research should be conducted on the anti-well technology extension deep shaft. Describes the extension of Tongkoukouquangou project extension, according to the actual situation of the development of a specific construction program, through a detailed comparison of programs, the final selection of the most appropriate program. The preparation, construction technology and construction technology are introduced, which provide some theoretical basis for the application of antihole technology in deep shaft and provide a good reference for the smooth development of similar projects in the future.
