Gently inclined ore bodies are recognized as one of the difficult-to-mine ore bodies. Under the condition that the mine production system is fixed, the conversion of mining for ore bodies with different occurrence conditions significantly affects the mine production efficiency and safety. When a mine converts from mining near-horizontal ore bodies to gently inclined-inclined ore bodies, the traditional method is faced with the problem that some stopes cannot utilize existing roadways for mining and cutting, and a large number of new mining preparation projects need to be developed. To address the above problems, a mining scheme of "arranging stopes perpendicular to the strike of the ore body, canceling cutting raise shafts, and using ore drawing drifts as the initial free surface and supplementary space" was proposed. This scheme can save some mining preparation projects such as trench roadways, medium-deep hole bottom pulling, ore drawing drifts and ore haulage roadways. The stability of this structure was demonstrated using FLAC3D software, and industrial tests were carried out on-site. The results show that the goaf model of stope 62-A has a relatively regular shape, basically no caving occurs and side walls, the ore loss rate is 2.3%, the dilution rate is about 8.5%, and the mining and cutting engineering quantity is reduced by about 14.8%. This scheme has advantages such as adapting to the change of ore body dip angle, simplifying stope structure and reducing engineering quantity, and provides a reference for the mining of similar ore bodies.

缓倾斜矿体是公认的难采矿体之一，而在矿山生产系统固定的条件下，不同赋存条件矿体的回采转换会显著影响矿山生产效率与安全。某矿山由近水平矿体转向缓倾斜-倾斜回采时，采用传统方法面临着部分采场无法利用现有巷道进行采切的问题，需要开拓大量新采准工程。针对以上问题，提出了“垂直矿体走向布置采场，取消切割天井，以出矿进路为初始自由面与补充空间”的回采方案，可节省堑沟巷道、中深孔拉底、出矿进路及出矿巷道等部分采准工程。通过FLAC3D软件论证了该结构的稳定性，并在现场开展工业试验。结果表明：采场62-A采空区模型形态较为规整，顶板及侧帮基本未发生冒落，矿石损失率为2.3%，贫化率约为8.5%，采切工程量减少约14.8%。该方案具有适应矿体倾角变化、简化采场结构及减少工程量等优势，为类似矿体回采提供了参考。
