结合小铁山矿技术改造的具体要求,作者于1986年参加技术考察组对瑞典博利登公司地下矿山进行了为期一月的现场考察和技术操作。重点考察了采矿工艺和设备管理。博利登公司矿山由于采用了合理的采矿工艺技术和对设备进行有计划的维修保养,因而获得了较商的经济效益。在众多的生产经验中最为突出的是广泛采用光面爆破技术和系统的锚杆支护,保证了坑内安全回采,又加上全面机械化作业,致使采矿效益高,指标优。这些矿山的充填工艺又具有特色,特别是脱水技术和接顶质量管理,对小铁山矿的技术改造都有实际意义,因此作者对上述问题作了重点介绍。
In light of the specific requirements of the technological transformation of Xiaoshan Iron Mine, the author joined the technical team in 1986 to conduct a one-month on-site inspection and technical operation on the underground mine in Boliden, Sweden. Focus on the mining technology and equipment management. Bolideng company mining due to the use of a reasonable mining technology and equipment for planned maintenance, which has been more than the economic benefits. Among the many production experiences, the most prominent is the widely used smooth blasting technology and system of bolt support to ensure the safe pit mining, coupled with full mechanized operation, resulting in high efficiency mining, excellent target. The filling process of these mines is distinctive. In particular, the dewatering technology and top quality management have practical significance for the technological transformation of Xiaoshan Iron Mine. Therefore, the author gives an introduction of the above problems.
