The upper middle section in the West 2^#Mining Area of Jinchuan Longshou Mine, with the mining method changed from underhand cut-and-fill mining to sublevel caving without sill pillar, was taken as an example for studying extraction of the orebody in a confined space from sublevels of stope. A combined scheme was prepared with different ore-drawing method for each sublevel. As for the first and second sublevels, the total amount of mined ore in the ore drawing is controlled to ensure the safe caving of roof and forming of overburden. And ore drawing by controlling ore dilution is adopted for the third sublevel for avoiding ineffective dilution, so as to achieve high-quality ore recovery. For the fourth sublevel, a scheme of ore drawing by controlling ore dilution in the normal stope drift plus ore-drawing by controlling cutoff grade in an auxiliary extraction drift is designed to achieve a full and effective ore recovery. Experiments were then performed with three groups of different ore-drawing schemes, and results show that a combined ore-drawing scheme can achieve safe and effective mining of orebody in a confined space, but also has a significant advantage in controlling loss and dilution of ores, which can bring the mine good economic benefit from mining. It is concluded that this research can provide scientific theory and technical guidance for the following engineering practice.

以金川龙首矿西二区上部中段由下向分层胶结充填法转无底柱分段崩落法开采为例，研究了限制性空间内无底柱分段崩落法采场各分段的矿石回采和回收特点，构建了一种以分段为放矿控制单元的组合式放矿方案：第一、二分段采用总量控制方式出矿以确保顶板安全冒落形成覆盖层；第三分段采用低贫化方式出矿以避免无效贫化，实现矿石的高质量回收；第四分段采用正常回采进路低贫化放矿+辅助回收进路截止品位放矿以实现矿石的充分、有效回收。设计并开展了3种不同放矿方案的物理实验，结果表明，本文设计的组合式放矿方案在限制性空间实现崩落法安全高效开采和损失贫化控制方面具有显著优势，可使矿山整体开采经济效益处于较优水平，为后期工程实践提供科学的理论和技术指导。
