摘　　要：介绍了西北地区某矿6_上^(-2)312工作面的概况及切顶卸压沿空留巷矿压观测目的、内容,给出了切顶卸压沿空留巷工作面矿压观测方案并进行了矿山压力及其显现的数据收集和分析。通过对切顶工作面液压支架受力及缩量监测和切顶卸压留巷顺槽围岩变形数据观测,得出矿压显现特征和顶板来压规律。同时矿压监测数据和研究结果对于了解和掌握同一采区的其他工作面矿压显现规律和巷道围岩变形具有一定的参考意义。Introduces the general situation of the 6up-2312 working face and the purpose and content of the mine pressure observation along the gob-end of a coal mine, and gives the observation scheme of mine pressure in the gob-left roadway with the top-cut pressure and the data collection and analysis of mine pressure and its manifestation. The characteristics of mine pressure and the law of roof pressure are obtained by observing the force and the shrinkage of the hydraulic support in the cutting face and the deformation data of the surrounding rock in the roadway. At the same time, the monitoring data and the results of mine pressure have some reference significance for understanding and mastering the law of strata pressure and deformation of roadway surrounding rock in the same mining area.
