Advanced identification and support method for strip mine slope dangerous rock mass
The invention belongs to the technical field of strip mine mining, and particularly relates to an advanced identification and support method for strip mine slope dangerous rock mass. According to the technical scheme, the advanced recognition and supporting method for the strip mine slope dangerous rock mass comprises the following steps that (1) the dangerous rock mass is subjected to advanced recognition; (2) advance construction supporting drilling is carried out; and (3) constructing a side slope advance support structure. According to the advanced identification and support method for the slope dangerous rock mass of the strip mine, the potential dangerous rock mass is identified and the slope at the corresponding position is reinforced in advance before the final slope is exposed, the rock mass and the support body bear excavation disturbance together, the strength of the rock mass can be fully utilized, the degradation degree of the mechanical property of the rock mass is reduced, and the construction efficiency is improved. And meanwhile, the reinforcement cost, the platform occupation time and the reinforcement period are greatly reduced.
本发明属于露天矿开采技术领域，具体涉及一种露天矿边坡危岩体超前识别与支护方法。本发明的技术方案如下：一种露天矿边坡危岩体超前识别与支护方法，包括如下步骤：1)危岩体超前识别；2)超前施工支护钻孔；3)边坡超前支护结构施工。本发明提供的露天矿边坡危岩体超前识别与支护方法，在最终边坡揭露前完成对潜在的危岩体进行识别并对相应位置处的边坡进行提前加固，岩体与支护体一同承受开挖扰动，可以充分利用岩体自身强度并降低岩体力学性质劣化程度，来保证边坡的稳定性，同时大幅降低加固成本、平台占用时间及加固周期。
