摘要
红透山矿业公司经过近60年的开采,在浅部的已关闭区域残留了一定数量的残矿资源,矿山对此部分资源回收的地质灾害和风险特性进行了模拟分析,拟定了回收的安全区域。经过对通风、运输等主要生产系统的恢复,创造了残矿回收的生产条件。矿山通过残矿回收工作的开展,创造了较大的经济效益。也认识到,对已关闭区域的残矿回收工作在技术和安全方面,还面临一系列的严峻挑战。
After nearly 60 years exploitation in Hongtoushan Copper Mine, a certain amount of residual ore resources are remained in shallow sealed zone. Aiming at the recovery of these resources, geological haz- ards and risk characteristics were simulated and analyzed. Production conditions of residual ore recovery were carried out on the base of the resumption of ventilation and transportation system and other primary production systems. Remarkable economic profits were created by the recovery of these residual resources. It is realized that there are still a series of severe challenges in terms of mining technology and safety in re- covering residual ore of sealed zone.
