摘要
通过多种矿压观测手段对11-2煤首采工作面压力显现及上下顺槽压力显现情况进行连续观测并分析,基本掌握了该煤层的来压规律,为同一煤层后续工作面的管理提供了参考数据。
The pressure appearance situation of head working place and the tail and main gate of 11-2 coal seam were observed and analysed by many observing means, and the pressure appearance law of this seam was known, which provided referential data for the management of next working place.
