锚杆锚索支护在近距离煤层的设计应用

Design and application of bolt and anchor support in the close distance coal seams

通过对煤峪口矿14#层近距离煤层采用U29棚和锚杆、锚索支护的定性分析,确定了14#层近距离煤层采用锚杆、锚索支护。通过锚杆、锚索定量计算,确定了14#层近距离煤层锚杆、锚索支护的合理参数。通过两个盘区四个工作面的实践,锚杆、锚索支护在近距离煤层的设计应用取得良好效果。

By the qualitative analysis of U29 shed and bolt, anchor cable supporting in No. 14 layer close distance coalseam, determined the use of bolt and anchor support in the close distance coal seams, and reasonable parameters. By thepractice of four working face of two panel, achieved good results.
