【摘要】：矿产资源的开发是一个复杂的系统工程,矿山的开采在很大程度上改变了矿山原有的环境,任何环节处理不当都可能对矿区周围的环境造成破坏,危及人类生命安全。当矿山位于城市、河流或交通干线附近时,采矿地的破坏性发展将成为城市和区域经济规划、实施的主要障碍之一。环境评价通常亦可称为“环境质量评价”,其目的就是从保护环境的角度出发,对人类社会行为,包括政策、法令等在内的一切活动造成的环境影响,进行定性与定量的评估。具体到矿产资源环境评价,就是运用一定的评价方法和手段,对矿业活动对环境的影响进行评估,从而促进矿产资源开发与环境协调发展。而在进行环境评价时也应考虑环境的资源构成或环境结构,使包括矿产在内的各种资源得以最好地利用和保护,因此,开展资源与环境联合评价具有十分重要的意义。工作区属青藏高原北部地震区柴达木地震亚区,处于布尔汗布达山构造强震带和柴达木中强地震带交界部位的北侧,地震活动较为频繁。区内无常住居民点,人类工程活动主要以矿产勘查、勘探、开采实验活动为主,目前尚无大规模开采活动。根据2010年青海省第一地质矿产勘查院所作环境地质调查发现不良地质现象类型有潜在不稳定斜坡、崩塌、滑坡、泥石流四类,其中以崩塌最为发育。论文以基于Arc Scene的矿山环境三维模型构建技术和基于Surpac软件的矿产资源三维建模技术为支撑,以《矿山环境综合调查与评价》地调项目为依托,将矿山环境的地质灾害信息与对应区域矿产资源的地下构造及岩体信息联系起来,直观分析地质灾害发生地点的构造与地层信息,客观评价人为因素对矿山环境造成的影响并制定出切实有效的开发方案,并以此为标准约束开采过程矿山开发人员的开采方式,杜绝违法开采造成重大地质灾害的现象的发生,为进一步的规范整顿提供技术支撑,真正实现资源与环境的联合评价。
[Abstract]:The exploitation of mineral resources is a complex system engineering. The mining of mines has changed the original environment of the mines to a great extent. Any improper handling of the links may damage the environment around the mining areas and endanger the safety of human life.When mines are located near cities, rivers or traffic lines, the destructive development of mining sites will become one of the main obstacles to urban and regional economic planning and implementation.Environmental assessment is usually referred to as "environmental quality assessment", the purpose of which is to carry out qualitative and quantitative assessment of the environmental impact caused by human social behavior, including policies, decrees and so on, from the point of view of environmental protection.The evaluation of mineral resources environment is to use certain evaluation methods and means to evaluate the impact of mining activities on the environment so as to promote the coordinated development of mineral resources and environment.In order to make the best use and protection of all kinds of resources, it is of great significance to carry out joint assessment of resources and environment.The working area belongs to the Qaidam earthquake subarea of the northern Qinghai-Tibet Plateau and is located on the northern side of the junction of the Burhan Budashan tectonic strong earthquake belt and the Qaidam moderate strong seismic belt. The seismicity is relatively frequent.There are no permanent residential areas in the area, and human engineering activities mainly consist of mineral exploration, exploration and mining experiments, but there are no large-scale mining activities at present.According to the environmental geological investigation carried out by the first Geological and Mineral Exploration Institute of Qinghai Province in 2010, it is found that there are four types of potentially unstable slopes, collapses, landslides and debris flows, among which the collapse is the most developed.The thesis is based on the 3D modeling technology of mine environment based on Arc Scene and the 3D modeling technology of mineral resources based on Surpac software.The geological hazard information of the mine environment is connected with the underground structure and rock mass information of the corresponding regional mineral resources, and the structure and stratigraphic information of the geological hazard location is analyzed intuitively.Objectively evaluating the impact of human factors on the mine environment and drawing up a practical and effective development plan, and taking this as a standard to restrict the mining methods of mine developers during the mining process, and to prevent the occurrence of major geological disasters caused by illegal mining,Provide technical support for further standardization and rectification, and truly realize joint evaluation of resources and environment.
