摘要
通过对沿空留巷顶板活动规律进行分析研究,提出了采空区侧充填体、巷道直接顶板和煤壁重点部位采取的加固方式,确保了小青矿W2713刨煤工作面和E1403综采工作面的安全顺利回采,进一步提高沿空留巷工艺的可靠性和适用性,推广应用范围。
Through the analysis of roof activity laws in gob-side entry retaining,the paper provided the reinforcing way of gob side backfill,tunnel nether roof,coal wall and other key support parts,which ensured the safety and smooth recovery of W2713 hewing and E1403 fully mechanized coal face,further improved the reliability and applicability of gob-side entry retaining technique and promoted the range of applications.
