三2煤皮带暗斜井揭煤支护技术研究

3_2 Seam Leather Belt Inside Slope Uncovers Coal to Support and Protect Engineering Research

在生产实际中,由于地质条件的复杂性,巷道随时穿越煤层和地质破碎带,研究托煤顶和控制松散岩层的支护技术,保证施工人员的安全、巷道的工程质量、工程施工的速度的很有必要,新庄煤矿在三2煤皮带暗斜井石门揭煤利用圆钢超前支护,锚网梁、锚索、喷浆联合永久支护取得了很好的效果,值得推广应用。

In production actual, as a result of the geological condition complexity, the tunnel passes through the coal bed and the geological crushed zone as necessary, the research holds the coal to go against supports and protects the technology with the control loose rock layer, guaranteed constructor＇s safety, the tunnel project quality, the project construction speed has the necessity very much, the Xinzhuang coal mine uncovers the coal in 32 seam leather belt inside slope Shimen to support and protect in advance using the round steel, anchor cable Liang, the anchor cable, the gunite union permanent supported and protected have obtained the very good effect, was worth promoting the application.
