| 摘 要： | 随着煤炭开采技术的发展及锚杆支护技术的推广应用,无煤柱沿空留巷已逐步替代宽煤柱。为了实现无煤柱开采,缓解采掘衔接,减少资源浪费,康保矿31503采面下巷道采用沿空留巷技术。沿空留巷采用锚索梁、密集及单体支柱进行支护,并采用顶板离层指示仪与十字布置法观测巷道顶板、底板和两帮的相对移近量,提供巷道矿压显现规律,为沿空留巷提供技术借鉴。 |
| 关 键 词： | 无煤柱 沿空留巷 支护 技术借鉴 |

| Abstract: | With the coal mining technology and the anchor supporting technology,no pillar gob-side entryretaining gradually replaced width pillar.In order to achieve no pillar mining,alleviate mining and digging cohesion,and reduce the waste of resources,Kangbao Coal Mine adopt the technology of gob-side entryretaining under 31503 face.Gob-side entryretaining adopt Leave the anchor along the empty lane of the beam,dense and monomer pillar for support,and USES the roof abscission layer indicator and the layout method of roof and floor,observation and two of the relative amount for closer,provide mine pressure regularity of appeared,along the left lane for empty provide technical reference. |
| Keywords: | no pillar gob-side entryretaining support technology reference |
