  中新xaxwaswaswasxilxilx3xax888社长沙12月18日电 (向xaxwaswaswasxilxilx3xax888一鹏 胡清)18日,一台开挖直径为5.63米的矿用掘进机在湖南长沙下线。该设备将参与赞比亚谦比希东南矿体巷道工程建设,这是中国矿用掘进机首次出口非洲。

  该台掘进机取名“中国有色二号”,长130米,重800吨,设计最小水平转弯半径50米,由中国铁建重工集团、中国十五冶金建设集团联合打造。

  据悉,赞比亚谦比希东南矿体是非洲第一座数字化矿山项目,本巷道工程长9.7公里,存在长距离硬岩、断层破碎带、小半径转弯、偏载掘进、长距离回退、罐笼运输、高地温等施工难题。

  铁建重工掘进机研究设计院工程师孙鑫健介绍,针对工程施工风险点和重难点,研制团队通过技术创新,采用模块化、小转弯、后配套免铺轨等设计,配置辅助撑紧系统、即时支护系统、超前地质预报系统,提高了掘进机对不良地质的适应性;同时定制化配置制冷系统、刀具在线监测系统等设备,提高操作人员舒适性,为工程建设提供支撑。

  据了解,赞比亚谦比希东南矿体项目总投资8.3亿美元,建设规模年采选矿石330万吨,生产铜精矿6万吨。巷道工程的建设,将大幅提高铜矿运输能力。(完)
