一般情况下,在地下开采影响范围内,无论地下采区与边坡体之间的相对空间位置关系如何,只要有地下开采的扰动作用,边坡的稳定状态都要受到影响。针对地下开采诱发地下开采工作面前方的滑坡的影响及其安全措施进行研究,通过对抗滑桩加固技术的优化,采用预应力锚索加固,最大限度地减少治理费用,保证开采边坡的安全。

Under normal circumstances, within the scope of underground mining influence, regardless of the underground relative space position relations between and the slope body ,as long as there is disturbance of underground mining, state of slope stability will be affected. In view of the underground mining induced by underground mining working face in front of the influence of the landslide and its safety measures were studied, through the optimization of anti-slide pile reinforcement technology, strengthened with prestressed anchor cable, minimize the cost of governance, but also to ensure safe mining slope.
