薄煤层巷道预应力锚固技术支护研究

Research on prestressed anchorage technology of thin coal seam roadway

北宿煤矿是全国非常有代表性的薄煤层矿井,随着薄煤层开采的快速发展和采煤机械化程度的提高,对巷道的掘进提出了更高的要求。结合现场实际,对薄煤层巷道预应力锚固技术支护进行研究。

Beisu Coal Mine of Yanzhou coal is national very representative of thin seam coal mine, along with the rapid development of thin seam mining, and the degree of coal mining mechanization, which proposed the higher requirements for the driving in thin seam coal, combined with the actual scene, put forward the pre-stress anchor supporting technology of thin coal seam.
