| 摘 要： | 本文通过收集山西晋城无烟煤矿业集团有限责任公司寺河矿首次采用6．2米液压支架回采特厚煤层的大采高工作面矿压数据，了解液压支架工作阻力变化情况，分析6．2米大采高工作面老顶来压特征，以此确定6．2米大采高工作面老顶初次来压、周期来压步距、强度等特征，得出回采空间支架与围岩相互作用关系，全面掌握6．2米大采高工作面采场矿压显现基本规律，为今后6．2米大采高采煤工序安排、顶板管理方式、采煤机械和支护设备的选型提供科学依据。

| Abstract: | In this paper, the collection of Shanxi Jincheng Anthracite Mining Group Co., Ltd. was first introduced Sihe Mine hydraulic support 6.2 meters thick seam extraction of large mining height face pressure data mining to understand the changes in the hydraulic support the work of resistance and to analyze the large mining 6.2 meters face to high-pressure characteristics of main roof to determine 6.2 meters high with large mining roof the first time to face pressure, pressure cycle step, the characteristics of strength, reached extraction space interaction between the stent and the surrounding rock, the full 6.2 meter high with large mining stope face the basic law of mine pressure behavior for the next 6.2 meters high with large mining process mining arrangements, roof management, mining machinery and support equipment to provide the scientific basis for selection. |
