高村采场区域环境影响分析

Analysis of Environmental Impact in Gaocun Stope Area

马钢矿业资源集团高村铁矿区域生产系统点多、面广,情况复杂,为更好地做好环境保护工作,从大气环境、水环境、噪声环境和固体废物环境4个方面分析了环境影响及防治措施;指出通过喷水降尘、汽车限速和覆土绿化减少有组织粉尘排放对周边环境的影响,使无组织废气浓度满足《铁矿采选工业污染物排放标准》(GB 28661—2012)要求;通过将矿坑水用于生产、抑尘及绿化,排土场淋溶水沉淀净化,生活污水经化粪池、沉淀池处理,喷淋废水等循环利用,实现了污水的零排放;通过选用低噪声设备及消声器,减振降噪,优化主要噪源区域布置,加强工人防护,建设绿化带降噪,汽车不超载、不超速、不集中上路,加强道路维修,铁路禁鸣及轨缝焊接,筑墙隔噪等措施,使项目噪声对周围环境没有明显不利影响;通过将除尘器收集的粉尘和生产石粉送排土场堆存,含油抹布与生活垃圾一道进行卫生填埋,废机油则委托有资质的单位处置,使项目固体废物较少影响到周边环境。项目污染防治措施有效、可行,无明显不良环境影响。

The production system of Gaocun Iron Mine regional of Masteel Mining Resources Group is complicated with many points and wide areas. In order to better protect the environment,the environmental impact and prevention measures were analyzed from four aspects: atmospheric environment,water environment,noise environment and solid waste environment. It was pointed out that the effect of organized dust emission on the surrounding environment was reduced through water spraying,vehicle speed limiting and soil greening,and the concentration of unorganized waste gas meets the requirements of Emission Standards for Pollutants from Iron Mining and Dressing Industry(GB 28661—2012). By using the pit water for production,suppressing dust and greening,precipitating and purifying the leaching water of dump,treating domestic sewage by septic tank and sedimentation tank,recycling spray waste water,zero discharge of sewage was achieved in the end. The project noise have no obvious adverse effect on the surrounding environment by choosing low noise equipment and muffler to reduce vibration and noise,optimizing the decoration of main noise source area. strengthening the protection of workers,building green belts for noise reduction,making car not overload,not speeding,not gathering on the road,strengthening the road maintenance,making no tooting and welding rail gap,building walls to block noise and other measures. The dust collected by the dust collector and the producted stone powder were sent to the dump for storage,the oilcontaining rags and household garbage were used for sanitary landfill,and the waste oil is entrusted to qualified units for disposal,so that the solid waste of the project will have less impact on the surrounding environment. The pollution prevention and control measures are effective and feasible without obvious adverse environmental impact.
