摘　　要：论文针对兖矿集团兴隆庄煤矿4324“超长”“孤岛”综放开采工作面条件,使用KSE-Ⅱ-1型钻孔应力计对巷道围岩应力进行了实测,通过对实测数据的分析,初步得出了该条件下巷道围岩应力分布特征,为巷道的支护提供了科学依据。According to the conditions of the number 4324 over-long and island fully mechanized top coal caving mining face, KSE-Ⅱ-1 borehole stress meter was used to measure the stress in the surrounding rocks of the gateway. With the analysis of the measured data, the paper has got the strezs distribution features of the surrounding rocks along the gateway of the face, which could be the scientific references to the support of the gateways.
