摘要： 山西兰花科创大阳煤矿6 m厚煤层综放工作面首次试验充填墙体沿空留巷，为确保工程质量，研究了沿空留巷
围岩活动的分期规律及空间特征，并对沿空留巷进行了全程的矿压监测。通过分析监测数据，得出了顶板的下沉规律，
给出了沿空留巷顶板前期活动、过渡期活动、后期活动、相对稳定4 个阶段的特征和范围，为沿空留巷动态治理、支护
方案优化提供了理论和实测依据。

Abstract: For the first time, the filling wall was tested in gob side entry retaining of the fully mechanized caving face in 6 m
thick coal seam in Dayang Coal Mine of Shanxi Lanhua Sci-tech Venture Co., Ltd.. In order to ensure the quality of the project,
the staged law and spatial characteristics of the surrounding rock activities of the gob side entry retaining were studied, and the
whole process monitoring of the mine pressure of the gob side entry retaining was carried out. Based on the analysis of monitoring
data, this paper obtained the law of roof subsidence, and pointed out the characteristics and scope of the four stages of roof
activity in the early stage, transition stage, later stage and relative stability. It provided a theoretical and practical basis for the
dynamic control and optimization of supporting scheme of gob side entry retaining.

Key words: thick seam; fully mechanized caving; gob side entry retaining; spatial characteristics; law of mine pressure
