采矿工艺及采掘设备与开采条件的优化结合，是实现高效率采矿的重要途径。以富家矿急倾斜不稳固薄矿体开采为工程背景，结合分层崩落采矿法与无底柱分段崩落采矿法各自特点设计了一种无底柱小分段崩落采矿法。详细介绍了无底柱小分段崩落采矿法采准工程布置、回采工艺过程及技术参数。富家矿80 m 中段单线翼部矿体小分段崩落采矿法开采试验应用取得了较好的技术经济效果，并为后续类似矿体回采提供了技术支持。
Optimized combination of mining conditions with mining methods and mining equipment is an impor-tant means to achieve efficient mining.The paper takes the extraction of steeply inclined unstable thin orebodies in Fu-jia Mine as the engineering background,devises a small sublevel caving method according to the respective character-istics of slicing caving and sublevel caving with no sill pillars.The layout of exploration lines in preparation stage,the extraction process and technical parameters of the small sublevel caving method are stated.The application in the wing orebody on the odd line side in the 80 m level gets satisfactory technical and economical results,and provides technical support for the extraction of similar orebodies.
