本文介绍了南非矿山的竖井掘进技术。指出提高吊桶提升速度、吊盘采用新型悬挂法、工作面采用履带式装岩机装岩、凿岩采用悬吊式重型凿岩机、灌注混凝土支护采用活动金属模板以及采用灌浆法处理地下水是提高竖井掘进速度的有效技术措施。在此条件下,竖井掘进速度达到300米/月以上。
This article describes the shaft mining technology in South Africa mines. It is pointed out that the lifting speed of the bucket should be increased, the new hanging method should be adopted for the hanger, the rock loader should be installed on the working face, the heavy rock driller should be used for rock drilling, the movable metal template should be used for the perfusion of concrete, and the groundwater should be treated by grouting. Effective technical measures for tunneling speed. Under these conditions, the speed of shaft excavation reaches over 300m / month.
