本课题是为了加快金川镍矿采准巷道的掘进成巷速度、保证巷道应有的稳定性,根据中国有色金属工业总公司(83)中色科字第871号文设立的研究项目。由金川有色金属公司、长沙矿山研究院和北京钢铁学院共同承担、分工合作。其中巷道支护部分的研究为我院负责研究与设计的主要任务。从1983年9月开始,针对金川二矿区“中瑞技术合作项目”,中上向机采盘区的条件,采用光面爆破与喷锚网支护技术经过三年的试验研究完成了课题研究的任务,达到了预期的目标,通过了部级技术鉴定。 我院采矿系金川课题组主要进行了该项目中的以下研究工作: 一、针对节理岩体中较大断面动压巷道等生产技术条件,通过试验,确定了以缝管
This topic is to speed up Jinchuan nickel mining roadway heading into the lane speed, to ensure the stability of the roadway, according to China Nonferrous Metal Industry Corporation (83) Zhongkeke word No. 871 text of the establishment of the research project. Jinchuan Nonferrous Metals Company, Changsha Institute of Mining and Beijing Iron and Steel Institute shared responsibility, division of labor. Among them, the study of roadway support is the main task of research and design of our institute. Starting from September 1983, the project was completed with three years of experimental study on smooth blasting and shotcrete bolting with the technical support project of Sino-Swiss cooperation project in Jinchuan No.2 mining area and the condition of medium-upper-deck mining area. Mission to achieve the desired goal, passed the ministerial technical appraisal. Jinchuan Mining Group in our institute mainly carried out the following research work in this project: First, according to the technical conditions of production of large pressure dynamic roadway in jointed rock mass,
