综采工作面三切眼对接及初采初放技术实践

Practice of three-cut butting and initial caving technology in fully mechanized mining face

以汾西矿业中兴煤矿1215综采工作面为背景,工作面由于受断层影响,布置成刀把工作面,为保证工作面顺利与三切眼对接及初采初放顶板安全,通过分析工作面情况,确定了合理的对接工序及初采初放技术措施,保证了工作面的安全生产。

Based on the 1215 fully mechanized mining face of Zhongxing coal mine in Fenxi Mining Industry,due to the influence of faults,the working face is arranged.In order to ensure the smooth docking of the working face with the three-cut eye and the safety of the first caving roof,the reasonable docking procedure and the technical measures of the first caving are determined through the analysis of the working face,which ensures the safe production of the working face.
