摘要： 目前，在综合机械化大采高一次采全高矿井中，常有顶板压力超前显现造成工作面顶板破碎难以维护，影响
生产的情况发生。通过研究山西兰花科创玉溪煤矿1301 综采工作面端头三角区破碎顶板注浆加固工艺，为类似大采高一
次采全高矿井工作面三角区破碎顶板注浆加固提供技术借鉴。

Abstract: At present, in the fully-mechanized full-seam mining wells with large mining height, the roof of the working face is
broken and difficult to maintain due to the advance appearance of roof pressure, which affects the production. This paper studied
the grouting reinforcement technology of broken roof in the triangular area at the end of 1301 fully-mechanized mining face in
Shanxi Lanhua Sci-tech Yuxi Coal Mine, so as to provide technical reference for broken roof in the triangular area of full-seam
mining face with large mining height.

Key words: coal mine; large mining height; working face end; grouting reinforcement
