| 摘 要： | 在对五阳煤矿西四采区 44 0 2综采放顶煤工作面矿压观测进行总结的基础上 ,分析了顶煤从开始回采到直接顶初次跨落后正常回采顶煤的变化情况和活动规律 ,将顶煤的运动分为承压变形区、裂隙区、压裂区、松散区和放煤区等五个区域。同时 ,通过与分层回采工作面矿压显现情况的对比 ,总结了综采低位放顶煤工作面矿压显现的特点 |
| 关 键 词： | 综采放顶煤 顶煤活动机理 矿压显现 |

| Abstract: | On the basis of summing up mechanical behavior of rockstrata of 4402 caving workface in fourth mining region in west of Wuyang coal mine.This paper analyzes changeable situation and movable rule of caving from beginning mining to regular mining after direct roof is striding down,caving is divided into five region with bearing pressure out-of-shape region,cracking region,fracturing region,loose region and falling coal region.In the meantime comparing with situation of mechanical behavior of rockstrata in levels mining workface,summing up feature of mechanical behavior of rockstrata in low caving workface. |
| Keywords: | sub-level caving movable mechanism of caving feature of mechanical behavior of rockstrata |
