摘要
通过对某矿两种不同类型锚杆的现场拉拔试验,得出了相同条件下摩擦锚杆的极限承载力大于砂浆锚杆的结论,并在实测资料的基础上,对该矿不同稳固程度的巷道的锚喷支护效果进行了分析和验算。
A conclusion that the maximum bearing capacity offriction anchor is greater than that of mortar anchor with samecondition is obtained by means of drawing test of two kinds of an-chor on the spot in a mine. Based on measurement data, the paperalso analyzes the support effect by mek - bolting and shotcretingfor different stable roadways in the mine.
