本文第一部分研究了瑞典基律纳试验研究矿山的设计和规划,下面将介绍大直径深孔空场采矿的设备、连续装载和辅助生产的情况。卢萨瓦拉矿需要钻凿直径165毫米的炮孔50000米,计划1984年底完成。炮孔从265米水平钻至365米装载水平,炮孔长度84～103米,平均92米。除D采场从320米水平向上钻凿约45米长的炮孔以外,所有炮孔都向下钻凿,彼此平行,倾角62°(矿体的平均倾角)。炮孔相距4米,沿走向间距
In the first part of this paper, the design and planning of the Kiruna experimental mine in Sweden are studied. The following is an introduction of the equipment for large-diameter deep-hole empty-field mining, continuous loading and auxiliary production. The Lusovala mine needs to drill 50,000 m of holes with a diameter of 165 mm and is scheduled to be completed by the end of 1984. Blast hole horizontal drilling from 265 meters to 365 meters loading level, the hole length of 84 to 103 meters, an average of 92 meters. All the holes were drilled downwards, parallel to each other, with an inclination of 62 ° (average inclination of the orebody) except that the D stope was used to drill a hole about 45 meters long up from 320 meters. 4 meters away from the hole, along to the distance
