| 中文摘要: |
| 根据夏楼铁矿开采技术条件,选取了分段空场嗣后充填采矿法以及12.5 m的分段高度,并初步确定了采场跨度范围.通过采用数值模拟方法,对采场初选的跨度进行研究,从采场顶板应力变化规律进行分析,得到了采场跨度的合理值为12 m. |
| 英文摘要: |
| According to the technical conditions of the mine,the subsequent backfilling mining method and section height of 12.5 m have been selected.And then,the range of span size of the stope have been preliminarily determined.Flac3D was used to simulate the two span sizes of stope preliminarily determined,the conclusion was obtained that the reasonable value of stope span was 12 m from the stope roof stress change law. |
