摘要
针对综采工作面过空巷的顶板控制特殊条件,采用了矿压显现、周期来压等的分析观测,确定了空巷合理支护方式及参数,获得了安全快速通过空巷,可为类似工作面的顶板控制积累经验。
Based on the special conditions of roof control while the fully-mechanized face crossing a gob,through the analyse of strata behaviors and periodic weighting,a reasonable support method and its parameters are determined to achieve quick and safe crossing the gob.
