三软复合顶煤层高应力区煤巷支护形式研究

Research on Support Form of Coal Roadway in Three Soft Composite Roof Coal Seam with High Stress Area

本文介绍了三软复合顶煤层掘进巷道过高应力区不同支护形式的实践过程。通过矿压观测确定高应力区煤巷支护方式及支护参数,选择安全可靠、经济的支护形式,寻求合理的围岩控制技术,解决了因围岩变形造成巷道失修的问题。

This paper introduces the practice process of different support forms in the high stress zone of three soft and compound top coal seam. Through the ore pressure observation, the support mode and support parameters of the coal roadway in high stress area are determined, the safe and economical support form is selected, and the reasonable surrounding rock control technology is sought, which solves the disrepair of the roadway caused by the deformation of the surrounding rock.
