摘要: 南芬露天铁矿目前正在进行三期扩帮四期开采工程,矿区工程地质条件较复杂,岩石以绿泥岩为主,遇水强度急剧降低,加之频繁生产爆破振动,致使边帮岩体多处出现张裂、滑塌、滚石等灾害。本研究以“滑动力大于抗滑强度是滑坡产生的充要条件”作为滑坡体滑动的主要判据,并应用“滑坡远程监测预警系统”在南芬露天矿滑坡体上构建了系统的“滑坡体远程监测网”。通过近10个月的现场试验,获得大量宝贵数据,为矿山安全可持续开采提供了安全保障。

Abstract: Nanfen open-pit mine now begin the third phase of expanding rib and the fourth phase of exploitation engineering. Engineering geological condition of mining area is complicated, and it mainly consists of green mudstone which has the characteristic of strength decreases sharply when meet water. Joint of the rock of the mining area is finely developed, in addition the frequently production blasting vibration, much slope have crack, slump, rolling stones. Finally, based on the theory that sliding force is greater than the anti-sliding force is the necessary and sufficient condition to occur the landslide as the sliding criterion, the principle and method for sliding force remote monitoring is presented, and a kind of systemic landslide remote monitoring network is established in the landslides of Nanfen Open-pit Mine. After 10 months site test, it shows that landslide monitoring system is scientific and practical.
