摘　　要：结合小青煤矿W2-713工作面开切眼的实例,介绍了刨煤机工作面开切眼断面形式对初采的影响,总结了在实际生产过程中的经验和做法,从更改切眼断面设计入手,着重对切眼的施工方法、技术要求以及支护参数进行了分析,给出了切眼断面形式改变方案,为今后相似地质条件下刨煤机工作面开切眼断面设计提供了可靠依据。Combined with the example of W2 -713 working face in Xiaoqing Coal Mine, it introduced the influence of open cutting see- tion form of plow face on the initial mining, and summarized some experience and practice in the actual production process. From the design of cutting section, it focused on the analysis of construction method, technical requirements and support parameters, and pro- posed the change program of cutting section form, thus provided the reliable basis for the design of open cutting section in plow face un- der similar geological conditions.
