爆破技术在综放工作面过大断层的实践应用

The Application of Blasting Technology in Fully-Mechanized Caving Face Passssing Large Faults

本文以山西汾西矿业南关煤业5301综放工作面过大断层为背景,采用直接推过的方式过落差8 m的断层,期间采取了爆破松动岩石、采煤机切割松动岩石的爆破技术方案。实践结果表明该爆破技术方案保障了5301综放工作面顺利通过断层,取得预期效果。

This paper takes the 5301 fully mechanized caving face of Nanguan Coal Mine in Fenxi Mining Area of Shanxi as a background, the blasting technology scheme of blasting loose rock and cutting loose rock by shearer was adopted during the process of directly pushing through the fault with a drop of 8 m. The practice results show that the blasting technology scheme ensures 5301 fully mechanized caving face to pass through the fault smoothly, and achieves the expected effect.
