摘要： 针对近距离煤层采空区下作业面巷道支护开展分析探究。结合具体工程实际，在分析原支护方案及存在问题
的基础上，对巷道支护方案开展优化研究，并对其实际应用效果做出实践分析。结果表明，优化后的方案实现了对巷道
顶底板及巷帮变形的有效控制，为下煤层的安全有效回采提供了保障，对矿井生产综合效益的提高提供了有力助推。

Abstract: Analysis and exploration was Carried out for the roadway support of the working face under goaf in close coal seams.
Combining with the actual project, on the basis of analyzing the original support scheme and existing problems, this paper carried
out optimization research on the roadway support scheme, and made a practical analysis of its actual application effect. The results
showed that the optimized scheme achieved effective control of the deformation of the roof and floor of the roadway and the roadway
side, providing a guarantee for the safe and effective mining of the lower coal seam, and providing a powerful boost to the
increase of the comprehensive benefits of mine production.

Key words: mine; close coal seams; goaf; roadway support; support optimization
