| 中文摘要: |
| 北京首云铁矿为太古宙“鞍山式”沉积变质条带状磁铁矿,断裂构造对矿体的破坏严重,使得局部矿体形态变得极为复杂,给后期的生产探矿工作带来了很大的困难。通过生产实践说明,在生产勘探过程中,坑内钻探比坑道探矿更具有优越性,更能满足矿山生产勘探的需要,从而达到为生产服务的目的,提高了矿山的生产效率和经济效益,坑内钻探技术手段在矿山生产勘探中完全可行。 |
| 英文摘要: |
| Miyun iron ore deposit belongs to Archean “Anshan type” sedimentary metamorphic banded magnetite type deposit,the iron orebody was seriously destructed by fault structure,the iron ore bodies locally become extremely complicated,thus it has brought great difficulties for the late stage exploration and mining production. The practical iron mining production shows that tunnel drilling has more advantages than the tunnel excavation,it can more satisfy the need of mining production and exploration,and achieve the mining purpose,it improves the production efficiency and economic benefit,thus tunnel drilling technology is feasible in the mine production and exploration. |
