自1965年乌达矿务局五虎山矿总进风立井首次使用锚喷支护(锚杆喷砂浆支护)以来,煤炭系统已有83个各类井筒在基岩段采用了锚喷作永久支护,其中约60％是提升井,40％是风井,总长度3万余米。这与井筒常用的现浇混凝土砌筑式支护相比,用量并不多,但因锚喷支护的施工方法有独特的优点以及七十年代“锚喷化”的影响,在一段时期的立井施工中较多使用,仅1974～1977年 Since the first use of the bolting and shotcreting support (grouting bolt support) at the Wuguoshan Mine General Intrusion Shaft in Wugu Mining Bureau in 1965, 83 types of wellbores have been used in the coal system for anchor injection Permanent support, of which about 60% is to enhance the well, 40% of the shaft, the total length of 30,000 meters. Compared with the commonly used cast-in-place concrete masonry support in wellbore, this amount is not much, but because of the unique advantages of the construction method of anchor and shotcrete support and the influence of “anchor spray” in the seventies, Vertical shaft construction more use, only 1974 ~ 1977 years
