巢湖北部山区矿山开采现状分析及保护措施

Analysis of the Present Situation and Protection Countermeasure of Mining in the North Mountain of Chaohu

巢湖北部山区处于扬子板块的西北缘、著名断裂——郯庐断裂带的东侧近旁侧,在该区40 km2的范围内地质遗迹丰富、典型、内容清晰、构造轮廓完整,且分布紧凑,是进行实践教学的极佳场所。同时区内沉积矿产丰富,其中以石灰石矿规模较大、开采量亦大。通过野外地质调查,发现矿山开发诱发了诸多地质问题,其主要问题是石灰石蕴藏(量)已接近枯竭;矿山开采带来的矿区环境问题、地质问题日益严重,对已有的一些弥足珍贵的地质遗迹造成了威胁,面临消失的危险。针对上述问题,提出对现有矿区的生态功能区域定位及对矿山环境进行有效整治与修复的建议,提出对该区地质遗迹的保护对策。

The north mountain of Chaohu is located at the northwest border of Yangtze plate and near the east side of the famous Tan-lu fault zone.Geological heritage are rich,typical,clarity and structure outline is complete and the distribution of geological phenomena are tight in the area of 40 km2.That is a great place for field practice teaching.The sedimentary deposits are rich in the area of where the limestone mining is larger and the amount of exploitation is bigger.Through the field geological survey,a lot of geological problems are brought out accompanying mine exploitation.The main problems are that the limestone reserves nearly depleted,the problems of environment and geology are serious increasingly,the precious geological heritages are under threat and danger of extinction.Aiming at the question above-mentioned,the suggestion about region orientation of ecological functions,effective remediation and restoration to the existing mines and the protection measures for geological phenomena are suggested.
