摘要
基于对顶板运动规律的分析 ,提出了大倾角坚硬顶板取消刀柱实现连续采煤的顶板控制方案 ;通过试采中矿压观测研究及时掌握顶板运动及矿压显现 ,指导了顶板控制方案的调整实施 。
Based on the analysis of roof movement, the paper points out that continuous mining method could be reached by proper roof control using pillarless support under steep angle with hard roof. The behavior of ground pressure in question can be mastered through the in site measurement, then original design can be further adjusted according to the observation.
