摘要
根据对巷道围岩移动趋势的分析，充分考虑到锚杆在垂直于锚杆轴向方向上与围岩的相互作用．将其用于软岩巷道底臌的防治，简化了软岩巷道施工工艺。矿井的实际应用表明支护效果是明显的。
On the basis of the motion tendency of the surrounding rock and with the interaction betweellthe slotted bolt and rock in the direction perpendicular to the bolt axis taken into full account, the slotted l,oltis used in the prevention and control of floor heave in the soft rock roadway. thereby the construction technique for this roadway is simplified and a considerable support effect is displayed in practice.
