Anchoring and treatment method for waste acid mine waste rock pile side slope
The invention belongs to the technical field of side slope anchoring and treatment, and relates to an anchoring and treatment method for a waste acid mine waste rock pile side slope, which comprises the following steps: installing an anchor pipe rod in a side slope area of a waste acid mine waste rock pile, injecting a repairing agent into the waste rock pile through the anchor pipe rod, injecting cement mortar into the waste rock pile, and maintaining until the designed strength is reached; an anchor pipe rod is installed in a deep area containing stock acid wastewater in a waste rock pile of the waste acid mine, and a repairing agent is injected into the waste rock pile through the anchor pipe rod. According to the method, the repairing agent and the cement mortar are injected into the waste acid mine barren rock pile through the anchor pipe rod, disturbance to the barren rock pile is reduced, the repairing agent can passivate an acid barren rock layer around the anchor pipe rod, corrosion to the anchor pipe rod is reduced, and the long-term effect of anchoring is guaranteed; and meanwhile, the anchor pipe rods in the side slope area can be more tightly combined with the loose rock-soil body, the anchoring effect is better, and the anchor pipe rods are additionally arranged in the deep area to be combined with repairing agent injection to reinforce treatment on the area containing stock acid wastewater.
本发明属于边坡锚固及治理技术领域，涉及一种废弃酸性矿山废石堆边坡的锚固及治理方法，在废弃酸性矿山废石堆的边坡区域安装锚管杆，通过锚管杆向废石堆中先注入修复药剂，再注入水泥砂浆，然后养护至达到设计强度；在废弃酸性矿山废石堆内含有存量酸性废水的深层区域安装锚管杆，通过锚管杆向废石堆中注入修复药剂。本发明采用锚管杆向废弃酸性矿山废石堆中注入修复药剂和水泥砂浆，减少对废石堆的扰动，修复药剂可以钝化锚管杆周围的酸性废石层，减少对锚管杆的腐蚀，保证锚固的长效性，同时边坡区域的锚管杆可以与松散的岩土体更加紧密的结合，锚固效果更佳，并在深层区域增加锚管杆结合修复药剂注入加强对含有存量酸性废水区域的治理。
