摘　　要：针对簸箕田金矿不同的矿体赋存条件,通过对矿体的倾角和厚度进行分类;结合矿山运行情况,提出了壁式全面回采后充填法、全面留矿后充填法、中深孔分段空场嗣后充填法3种相对应的开采方式。通过矿山生产应用表明,3种采矿法均能满足安全高效、低贫化、低损耗的矿山开采管理要求。该研究为矿山的高质量、可持续发展提供了坚实的技术基础,在不同类型的地下矿体中均能获得较好的经济效益。According to the different occurrence conditions of ore bodies in Bojitian Gold Mine,the dip angle and thickness of ore bodies are classified.Combined with the operation of the mine,three corresponding mining methods are proposed,namely,wall-type full stoping and filling method,full shrinkage and filling method,and medium-deep hole sublevel open stoping and subsequent filling method.The application of mine production shows that the three mining methods can meet the requirements of safe and efficient,low dilution and low loss mining management.The research provides a solid technical foundation for the high quality and sustainable development of the mine,and can obtain better economic benefits in different types of underground ore bodies.
