不规则工作面小角度边采边撤支架回采的探索与实践

晓明矿现处于尾采阶段,为提高煤炭资源回采率,受地质条件影响会将工作面布置成不规则形状,回采时增加施工工艺[1]和施工难度,通过对S1701工作面后三角点顶板的有效支护、自制加工设备,顺利完成了小角度边采边撤支架[2]的回采施工任务,保证矿井接续顺畅。

Xiaoming Mine is now in the tail mining stage. In order to improve the recovery rate of coal resources, the working face will be arranged in an irregular shape due to the influence of geological conditions, and the construction technology and construction difficulty will be increased during mining. Through the effective support and self-made processing equipment for the roof of the back triangle point of S1701 working face, the mining construction task of small angle mining while withdrawing support has been successfully completed, so as to ensure the smooth continuity of the mine.
