摘要: 介绍了亿欣煤业XV1307 工作面的基本情况,分析了工作面沿空留巷技术的应用。通过分析工作面巷道布置情
况、断面规格以及支护方式等情况,计算了巷道围岩压力值,并结合工作面实际情况对沿空留巷技术进行了分析,确定
了工作面正常回采期、特殊时期相应的顶板控制方式,为沿空留巷技术的实际应用探索了一条安全、高效、经济的途径。

Abstract: This paper introduced the basic situation of XV1307 working face of Yixin Coal Industry Co., Ltd., and analyzed the
application of the gob-side entry retaining technology in working face. By analyzing the roadway layout, section specification and
support mode of the working face, the pressure value of the roadway surrounding rock was calculated, and the gob-side entry
retaining technology was analyzed in combination with the actual situation of the working face, the corresponding roof control
modes in the normal mining period and special period of the working face were determined, which explored a safe, efficient and
economic way for the practical application of the gob-side entry retaining technology.

Key words: gob-side entry retaining; support mode; roof control; supporting intensity; mining area; roadway
