Waste mine treatment method
The invention relates to the technical field of mine treatment, and particularly discloses a waste mine treatment method. The abandoned mine treatment method comprises the following steps: S1, risk assessment: assessing underground water risks and environmental safety risks around an abandoned mine, and dividing risk grades; s2, pretreatment is conducted, specifically, slag and waste buildings on the periphery of a mine are dismantled, and construction risks are eliminated; s3, backfilling a gravel layer; s4, water stop material backfilling is conducted, specifically, water stop material backfilling is conducted on the gravel layer, and the water stop material comprises cement water glass, concrete, clay and an expanding agent; the expanding agent is prepared from polyethylene glycol dimethacrylate, alginate and starch according to the mass ratio of (10 to 18) to (7 to 15) to (3 to 8); and S5, sealing a well mouth: sealing the well mouth by adopting backfill soil, and recovering vegetation. The abandoned mine treatment method has the advantages that leakage is resisted, and water body layer-crossing pollution is reduced.
本申请涉及矿井治理技术领域，具体公开了一种废弃矿井治理方法。一种废弃矿井治理方法，包括如下步骤：S1：风险评估：对废弃矿井周围的地下水风险和环境安全风险进行评估，划分风险等级；S2：预处理：将矿井周边的矿渣和废弃建筑物进行拆除，排除施工危险；S3：碎石层回填；S4：止水材料回填：在碎石层上进行止水材料回填，所述止水材料包括：水泥水玻璃、混凝土、粘土、膨胀剂；所述膨胀剂由聚乙二醇二甲基丙烯酸酯、藻酸盐、淀粉按质量比(10‑18):(7‑15):(3‑8)组成；S5：井口封闭：采用回填土对井口进行封闭，恢复植被。本申请的废弃矿井治理方法具有抗渗漏、降低水体串层污染的优点。
