神东矿区大采高综采工作面过空巷期间的岩层控制研究

The Research of Strata Control for Fully-Mechanized Coal Face with Large Mining Height While Passing Through the Empty Drift

综采工作面过空巷一直是煤矿开采没有解决好的技术难题,哈拉沟煤矿综采队共通过9条大断面空巷,总长超过2000多米。本文通过对02210综采工作面和02209综采工作面过02202运顺空巷和03回顺空巷期间的顶板岩层活动规律研究,力求找出综采工作面过大断面空巷的岩层控制技术,为今后大采高综采工作面过空巷提供参考依据。

Passing through the empty drift with fully-mechanized coal face is always a technical problem that cannot be solved with a good way during mining.Fully-Mechanized coal mining team of Halagou Coal has passed through 9 empty drift with large sections,and the total length has exceed 2,000 meters.Through researching on the activity regularity patterns of roof strata when No.02210 and No.02209 fully-mechanized coal faces were passing through No.02202 transporting empty drift and No.03 backing empty drift,this article strove to figure out strata control techniques for fully-mecha-nized coal face with large mining sections,so that it can supply some references for similar works in the future.
