摘要
正利煤业14-1105工作面为沿空掘巷工作面。为进一步掌握中深部、较高应力、复合顶板、较大采高、强采动典型开采条件下巷道矿压显现规律,同时为接续巷道乃至下位煤层实施小煤柱沿空掘巷提供借鉴经验和技术依据。
No.14-1105 working face of Zhengli Coal Industry is gob-side entry driving working face.In order to further master the strata behavior law of roadway under the typical mining conditions of middle depth,high stress,composite roof,large mining height and strong mining,and provide reference experience and technical basis for the implementation of gob-side entry driving with small coal pillars in the roadway and even in the lower coal seam.
