摘要： 针对K2灰岩顶板大巷支护的问题，以神农煤业一采区北延胶带大巷为工程地质背景，通过巷道围岩物理力学
参数测试，对巷道围岩顶板进行了分类；在参考邻近矿井同类地质条件巷道支护参数的基础上，结合神农煤业的围岩条
件和支护情况，综合确定了巷道锚固支护方案。井下试验表明，巷道支护方案合理、可靠，围岩变形小。

Abstract: In view of the problem of K2 limestone roof roadway support, this paper took the north extension belt roadway of No.1
mining area of Shennong Coal Industry Co., Ltd. as the engineering geological background, and classified the surrounding rock
roof of the roadway by testing the physical and mechanical parameters of the surrounding rock of the roadway. On the basis of
reference to the similar geological conditions of the adjacent mines, combined with the surrounding rock conditions and support
conditions of Shennong Coal Industry Co., Ltd., it comprehensively determined the roadway anchoring support scheme. The
underground test shows that the support scheme is reasonable and reliable, and the deformation of surrounding rock is small.

Key words: K₂ limestone; mechanical parameter test; roof classification; anchoring support scheme
