近距离煤层工作面巷道支护技术的研究

Research on Support Technology of Roadway in Close Distance Coal Seam Face

结合某近距离煤层工作面巷道实际情况,研究了巷道支护技术方案,对顶板支护和两帮支护技术参数进行了分析。基于有限元分析结果和实际监测结果发现,提出的巷道支护方案达到了理想效果,有效地避免了巷道变形,为确保工作面安全奠定了坚实的基础。

Combined with the actual situation of the roadway in a short-distance coal seam, the technical scheme of roadway support was studied in detail, and the technical parameters of roof support and two-side support were analyzed. Based on the results of finite element analysis and actual monitoring, it is found that the proposed roadway support scheme achieves the desired effect and effectively avoids roadway deformation. It has laid a solid foundation for ensuring the safety of the working surface.
