摘要： 针对东新煤矿21222 工作面沿空掘巷围岩控制问题，建立了被研究回采工作面煤层及上部岩层和下部底板岩
层的结构模型并详细分析，为21222 工作面沿空掘巷窄煤柱合理宽度的确定提供参考。通过分析采掘期间巷道的应力分
布、巷道的两帮变形量、锚杆（索）的作用机理，针对不同支护参数对巷道性能的改善，合理确定了21222 工作面沿空
掘巷的支护强度，最终确定了21222 工作面沿空掘巷的围岩控制技术体系。

Abstract: In view of the surrounding rock control problem of gob-side entry driving in 21222 working face of Dongxin Coal Mine,
this paper established and analyzed the structural model of coal seam, upper rock stratum and lower floor rock stratum in the
studied working face in detail, which can provide a reference for the determination of reasonable width of narrow coal pillar of gobside
entrydriving in 21222 working face. By analyzing the stress distribution of the roadway during mining, the deformation of the
two sides of the roadway, and the action mechanism of the bolt (cable), aiming at the improvement of the roadway performance by
different support parameters, the support strength of gob-side entrydriving in 21222 working face was reasonably determined, and
finally the surrounding rock control technology system of gob-side entrydriving in 21222 working face was determined.

Key words: gob-side entry driving; support; coal pillar width
