摘　　要：近年来,高原采矿活动日渐频繁。为实现西藏地区环境保护与工业经济协调发展的理念,针对甲玛矿高寒、缺氧的开采技术环境,研发机械化程度高、生产能力大的采矿方法非常有必要。基于此,综合比较推荐采用大直径束孔高分段空场嗣后充填采矿方法,其中大间距束孔布置参数是关键。通过采用理论计算法、爆破漏斗试验法、经验类比法等方法,推荐了甲玛矿束孔爆破参数,但仍需现场工业试验进一步确认与优化,为实现甲玛矿大规模机械化开采奠定基础。Recently, plateau mining activities have become quite common. In order to realize the concept of achieving the balance between environment protection and industry development in Tibet, and considering the alpine and hypoxia conditions for mining in Jiama Mine, it is necessary to develop a highly-mechanized mining method with large production capacity. Therefore, through a comprehensive comparison, it is recommended to a large-diameter bundle blastholes high-sublevel cut and fill mining method. It is critical to get the arrangement parameters of large span bundle blastholes. In this paper, three methods including theoretical calculation, blasting crater test and empirical analogy are adopted to determine the bundle blastholes blasting parameters, which shall be further verified through site industrial tests, to lay a basis for the large-scale mechanized mining in Jiama Mine.
