中文摘要：
针对归来庄金矿露天转地下开采过程中面临的诸多难题,以动态调控的思想,提出了结合工程实际,在露天转地下过程中对露天转地下的各个工艺、工种、工序在数量和程度上进行合理安排与控制,如采取联合开拓运输系统、开展双向对掘施工方案和布置措施工程,大大提升井下工程施工进展;开展高陡边坡稳定性分级和锚索锚网分区加固工作,维护露天边坡安全;进行不扩帮延伸回采及同步境界矿柱铺设工作,隔离露天与地下生产;推进多作业地点、多种采矿方法并行作业,确保露天产转地高效生产;实施多种防措施及排水工程,力保大水矿山露天转地下安全生产。露天转地下安全高效动态调控技术的研究与合理、有序的施工组织,为归来庄露天矿实现不减产平稳过渡成功,安全、高效回采提供了保证。
英文摘要：
In view of mary difficulties in underground construction,put forward the proposal of dynamic monitoring in the process from open-pit to underground mining,rational arrangement and monitoring in the number and degree should be adopted to related techniques,working category and procedures.The underground construction was greatly improved by applying united exploiting and transporting system,as well as bidirectional digging scheme and layout;ensured the safety of open-pit side slope by grading the stability of high and steep side slopes and sectioning and reinforcing the anchor cable and net;separated open-pit from underground production by applying the extension method without expanding side slope and allocating in-phase separated pillars;ensured highly efficient production from open-pit to underground by conducting multi-location and multi-method operation;improved the safety for Large waterflow mine from open-pit to underground by carrying out various precautious and draining measures.With the further study of dynamic monitoring technology in the safe and efficient mining from open-pit to underground,as well as the rational and orderly construction organization,Guilaizhuang Open-pit Mine witnessed a successful transition from open-pit to underground mining without any decreasing output.Meanwhile,the safe and efficient exploitation may be ensured in this case.
