摘要： 以大采高小煤柱回采巷道围岩稳定性和控制技术为研究对象，通过对该类巷道围岩结构进行分析发现，此类
围岩基本顶的初次垮落容易形成“O-X”断裂现象。通过对结构模型进行稳定性分析，得出了影响大采高小煤柱回采巷
道围岩稳定性的因素，并在此基础上提出了对大采高小煤柱回采巷道的维护手段。

Abstract: Taking the mining roadway surrounding rock stability and control technology of the small coal pillar with large mining
height as the research object, through the analysis of the surrounding rock structure of this kind of roadway, it was found that the
primary collapse of the basic roof of this kind of surrounding rock was easy to form the "0-X" fracture phenomenon. Through the
stability analysis of the structural model, the factors influencing the stability of the mining roadway surrounding rock of the small
coal pillar with large mining height were obtained, and the maintenance measures for the mining roadway of the small coal pillar
with large mining height were put forward on this basis.

Key words: small coal pillar with large mining height; mining roadway; surrounding rock control
