在伟大领袖毛主席“备战、备荒、为人民”的光辉思想照耀下,在无产阶级文化大革命的推动下,为大打矿山之仗,结束钢铁工业十年徘徊,我国矿山的革命工人、革命干部和革命科技人员,高举“鞍钢宪法”的伟大旗帜,发扬独立自主、自力更生、奋发图强、敢于斗爭、敢于胜利的革命精神,在较短时间內试验研究成功了喷射混凝土先进技术,并在矿山井巷工程中得到广泛的应用,取得很好的效果。喷射混凝土是一种强度高,粘结力强和抗渗性能好的新型支护结构。它与捣制混凝土此,具有与岩石结合紧密、质量好、速度快、效率高,不用模板等特点,是把运输、浇注、捣固结合在一起的新型支护方法。它的研究成 Under the glorious ideology of “preparing for war, preparing for famine and for the people” of great leader Chairman Mao, and under the impetus of the Great Proletarian Cultural Revolution, to end the ten-year lingering iron and steel industry in the battle of the mines, the revolutionary workers and revolutionary cadres in our mines And revolutionary scientists and technicians hold high the great banner of “Ansteel Constitution” and carry forward the revolutionary spirit of independence, self-reliance, work hard, dare to struggle, and courage to victory. In a relatively short period of time, we successfully tested the advanced technology of shotcrete, In a wide range of applications, and achieved good results. Sprayed concrete is a new type of supporting structure with high strength, strong bonding and impermeability. It is with the ramming of concrete, with the rock with close, good quality, fast, high efficiency, without template and so on, is the transport, casting, tamping together a new type of support methods. Its research into
