煤仓是煤矿硐室中施工难度较大的一项工程,在工作面岩层稳定、无瓦斯和涌水的情况下,施工直立式煤仓多采用普通反井法---混凝土支护。本文以仙亭煤矿2#皮带+300 m煤仓为例阐述了普通反井法在特定条件下立井煤仓中的应用,为该类巷道施工提供经验借鉴。
煤倉是煤礦硐室中施工難度較大的一項工程,在工作麵巖層穩定、無瓦斯和湧水的情況下,施工直立式煤倉多採用普通反井法---混凝土支護。本文以仙亭煤礦2#皮帶+300 m煤倉為例闡述瞭普通反井法在特定條件下立井煤倉中的應用,為該類巷道施工提供經驗藉鑒。
매창시매광동실중시공난도교대적일항공정,재공작면암층은정、무와사화용수적정황하,시공직입식매창다채용보통반정법---혼응토지호。본문이선정매광2#피대+300 m매창위례천술료보통반정법재특정조건하립정매창중적응용,위해류항도시공제공경험차감。
Coal bunker construction is difficult in the cavern of a project ,in which raised -shaft method-concrete support is frequently applied under the conditions of stable strata at workface without gas and water gushing . Taking the 300-meter coal bunker with No .2 belt in Xianting Colliery as an example ,the author expounds the application of general raised -shaft method in the construction of coal bunker in vertical shaft under certain con-ditions ,which provides the reference for similar roadway construction .
