深圳市废弃矿山地质环境现状及影响评价

本文收集和调查了深圳市88处废弃矿山,其中25处经过治理已完成恢复利用,但剩余63处仍然存在地质环境问题。主要的地质环境问题有地质灾害、地形地貌景观破坏和土地资源破坏3种。其中,地形地貌景观破坏、土地资源破坏在深圳市废弃矿山中普遍存在,地质灾害隐患相对较少。结合深圳市实际情况,首先进行废弃矿山地质环境条件复杂程度评价以及废弃矿山地质环境问题危害程度评价,并在此基础上进行了废弃矿山地质环境影响评价。结果显示：深圳市存在地质环境问题的废弃矿山中对地质环境影响轻微的占26.99%,对地质环境影响较严重的占4.76%,对地质环境影响严重的占68.25%。表明深圳市废弃矿山总体情况不容乐观,需要进行进一步的治理。

Present situation and impact assessment of abandoned mines geological environment in Shenzhen city

In this paper, 88 abandoned mines in Shenzhen were collected and investigated. Among them, 25 have been restored and utilized after restoration and treatment, while the remaining 63 still have geological environment problems. The main geological environment problems include geological disasters, destruction of landform and landscape, and destruction of land resources. Among them, the destruction of landform and landscape and the destruction of land resources are common in abandoned mines in Shenzhen, and the hidden dangers of geological disasters are relatively few. Combined with the actual situation, the complexity degree of geological environment conditions of abandoned mines and the hazard degree of geological environment problems of abandoned mines were firstly evaluated, and on this basis, the impact assessment of geological environment of abandoned mines was carried out. The results show that among the abandoned mines with geological environment problems in Shenzhen, the ones with slight impact on the geological environment account for 26.99%, the ones with serious impact on the geological environment account for 4.76%, and the ones with serious impact on the geological environment account for 68.25%. It shows that the general situation of abandoned mines in Shenzhen is not optimistic and further treatment is needed.
