阜新市新邱博大煤矿原设计采用井工开采，开采原井工和露天煤矿的剩余煤 量。为提高矿山采掘水平，实现矿山生产规模化、机械化。阜新市博大煤矿拟将进 行技术改造，改为露天开采。对本矿技术改造后所采用的开采工艺、设备类型、开 采参数、开采方法（剥采程序、开拓运输系统、各工艺环节作业方式）、边坡稳定 性等进行可行性分析，确定生产剥采比，提出确保边坡稳定的安全技术措施。选择 单因子评价方法对该矿的环境空气、水、声音及生态环境等方面进行评价，并分析 评价结果。最后研究技术改造后技术经济效益和环境影响经济效率。经研究和分析 评价得出本矿技改在技术和环境上都具有相当的可行性。同时该矿在技改实施后在 环境、经济和社会方面均取得了一定的效益，达到了三个效益的统一。 关键词：露天矿；技术改造；环境评价 ；可行性；经济效益- II - Abstract Fuxin coal the original design and new high by work well expand, mining the original work well and the rest of the open coal mine coal mining extraction is to improve the level and realize large-scale production mechanization mining for and will be proposed to coal mine Fuxin, technical renovation, to open this ore mining after technical innovation of the mining process equipment type mining parameters of mining method (stripping program development transport system every process sectors practices) slope stability of feasibility analysis, determination of the production stripping ratio, put forward to ensure the stability of slope safety technical measures choose single factor evaluation method to the mine environment air water ecosystem voice and evaluation, and analysis and evaluation results after technical innovation of the technical and economic benefits and environmental impact economic efficiency by research and analysis and evaluation of this ore that Key Words: Surface mine; technique rebuilt; Environmental evaluation; Feasibility Economic benefit- III - 摘要 ........................................................
