摘　　要：根据某露天煤矿项目的特殊开采条件,在传统的露天开采方法无法满足项目需求的前提下,将疏浚开采方法应用于露天煤矿的开采当中,基于疏浚开采方法应用于露天煤矿中的工艺流程及煤层开采对疏浚开采方法提出的几个关键性要求进行论述。结果表明:疏浚开采方法可应用在地下水水位无法降低到正常工况水平或开采工作本身就需在水中进行的煤层开采中。According to the special mining conditions of a certain open-pit coal mine project,the traditional open-pit mining methods can't meet the demand of project.We apply dredge mining method to the mining of open-pit coal mine.Based on dredging mining method which is applied to the process flow and coal seam mining in open-pit coal mine,the article puts forward several key requirements to dredge mining method.The results show that dredging mining method for water level cannot be reduced to the normal working condition level or coal seam mining should be carried out in the water.
