为了掌握极近距离联合开采工作面矿压显现规律，实测了灵石煤矿极近距离9#煤与10#煤联合开采工作面的支架工作阻力，分析了进行联合开采回采工作面顶板的矿压显现规律。研究表明：进行联合开采的090105和100105回采工作面都具有明显的周期来压现象，工作面周期来压步距分别为13.4 m和10.6 m；下煤层工作面比上煤层工作面动压影响大，矿压显现更明显，下煤层工作面来压时间持续更短。为极近距离煤层联合开采矿压控制提供了重要依据。

In order to master the very close combined mining face underground pressure behaviors, measured the combined mining working faces support resistance of the ultra-close multiple seams 9 # and 10# in Lingshi coal mine,analyzed the mine pressure regularity of the combined mining working faces. It’s showed that the combined mining working faces of 090105 and 100105 have appeared obvious periodic roof pressure, face periodic weighting interval of 13.4 m and 10.6 m respectively, and the lower working face have a bigger dynamic pressure influence, more obvious mine pressure appear and a shorter periodic roof weighting pace. The study will provide an important basis for combined mining pressure control in the ultra-close multiple coal seams.
