【摘要】：随着矿山开采强度的日益加大,导致矿区泥石流、滑坡、地面塌陷等地质灾害频发以及环境污染日趋严重,对矿区地质环境问题进行详细分析并进行准确评价,对于进一步采取针对性的治理措施具有重要意义。以宝鼎矿为例,采用ArcGIS软件,对矿区比例尺为1∶50 000、多光谱波段分辨率为2.44 m、全色波段分辨率为0.61 m的Quick Bird遥感图像进行解译,分析了矿区滑坡、泥石流、地面塌陷等地质灾害以及水体、大气、粉尘等环境污染的分布区域,并统计、计算得出矿区滑坡、泥石流、地面塌陷区分别有12,4,10处,矿区水体、大气、粉尘污染的面积分别为0.255 9,3.211 7,0.028 4 km~2。在上述分析的基础上,采用模糊层次分析法(Fuzzy analytic hierarchy process,FAHP)对矿区地质环境进行了综合评价,选取地质环境、地质灾害、环境污染作为一级评价指标,各指标分别包含地形地貌、水文地质、地层岩性,滑坡、泥石流、地面塌陷,大气污染、粉尘污染、水体污染等二级评价指标。研究表明:矿区地层岩性复杂,水文地质条件恶劣且受地形地貌控制,地质环境评价为Ⅲ类较差级别;矿区滑坡、泥石流和地面塌陷分布较广且数量较多,地质灾害评价为Ⅲ类较差级别;矿区大气污染、粉尘污染较严重,局部存在水体、固体废弃物污染,环境污染评价为Ⅱ类一般级别;总体上矿区地质环境质量较差,总体评价为Ⅲ类较差级别,亟需采取措施进行治理。
[Abstract]:With the increasing intensity of mining, frequent geological disasters such as debris flow, landslide, ground collapse and environmental pollution become more and more serious. The geological environment problems in mining area are analyzed in detail and evaluated accurately. For the further adoption of targeted governance measures have important significance. Taking Baoding Mine as an example, the Quick Bird remote sensing images with a scale of 1:50 000, a multispectral band resolution of 2.44 m and a panchromatic band resolution of 0.61 m are interpreted by using ArcGIS software. The landslide and debris flow in the mining area are analyzed. The distribution areas of geological hazards such as ground collapse and environmental pollution such as water body, atmosphere, dust and so on are calculated and calculated. There are 12 ~ 4 ~ 10 geological hazards in mining area, including landslide, debris flow and ground collapse, respectively. Water body of mining area, atmosphere, etc. The area of dust pollution was 0.255 ~ 3.211 ~ (7) ~ 0.028 4 km ~ (2) ~ (2) respectively. On the basis of the above analysis, the comprehensive evaluation of the geological environment of the mining area is carried out by using the fuzzy analytic hierarchy process (Fuzzy analytic hierarchy). The geological environment, geological hazard and environmental pollution are selected as the primary evaluation indexes, and each index includes the topography and geomorphology, respectively. Hydrogeology, stratigraphic lithology, landslide, debris flow, ground collapse, air pollution, dust pollution, water pollution and other secondary evaluation indicators. The study shows that the strata and lithology are complicated, the hydrogeological conditions are bad and controlled by topography and geomorphology, the geological environment evaluation is of the third grade, the distribution of landslide, debris flow and ground collapse in mining area is relatively wide and the quantity is large. The evaluation of geological hazard is classified as Class 鈪，
