摘　　要：通过对双龙煤矿1501综采工作面煤层顶板初次来压和周期来压步距、工作面支架支护强度等数据的监测,在分析研究的基础上得到了软弱围岩结构中厚煤层综采工作面矿压显现活动规律,并对工作面支架的适应性进行了分析和探讨。Based on in- situ pressure monitoring of 1501 fully mechanized mining face in Shuanglong Coal Mine, initial and periodic weighting distance, supporting strength of support were determined, the strata behaviors laws of fully mechanized mining face in medi- um thick seam of weak surrounding rock are obtained based on the analysis. Support adaptability of working face are analyzed and dis- CUSSe（l.
