矿山地质环境影响评估——以双胜镇龙头山凝灰岩矿为例

为了减少或避免采矿活动对矿山地质环境的影响破坏，有效防治矿产资源开发导致的矿山地质环境问题。以双胜镇龙头山凝灰岩矿为例，对其矿山地质环境影响进行评估，重点为现状评估和预测评估。评估区地质环境条件复杂程度中等，评估区重要程度为较重要区，矿山地质环境影响评估级别为一级。现状评估将评估区分为矿区道路、探槽、其他区域(地质环境影响较轻区)。预测评估将评估区分为矿山地质环境影响程度严重区、较严重区、较轻区3个区。其中，露天采场为地质环境影响严重区；碎石加工场、表土存储场、排渣场为地质环境影响较严重区；办公生活、矿区道路区为地质环境影响较轻区。研究为实现矿产资源开发与环境保护协调发展提供了依据。

Mine geological environmental impact assessment:taking Longtoushan Tuff Mine in Shuangsheng Town as an example

In order to reduce or avoid the impact of mining activities on the mine geological environment，and effectively prevent and control the mine geological environment problems caused by the development of mineral resources.Taking Longtoushan tuff mine in Shuangsheng Town as an example，this paper evaluated the geological environment impact of the mine，focusing on the current situation assessment and prediction assessment.The complexity of geological environment conditions in the assessment area is medium，the importance of the assessment area is relatively important，and the mine geological environment impact assessment level is Grade Ⅰ.According to the current situation assessment，the assessment is divided into mining area roads，exploration trenches and other areas，which are less affected by geological environment.According to the prediction and assessment，the assessment is divided into three areas:the area with serious geological environment impact，the area with more serious geological environment impact and the area with less serious geological environment impact，among which the open pit is the area with serious geological environment impact.Gravel processing yard，topsoil storage yard and slag disposal yard are areas with serious geological environment impact.The office and living area and the road area of the mining area are the areas with less geological environment impact.The study provides a basis for the coordinated development of mineral resources development and environmental protection.
