南美热带雨林地区露天金属矿山排土场施工措施及方法

南美洲热带雨林地区有着多雨的气候和复杂的地质条件,在露天金属矿山开采施工过程中,既要保证排土场的稳定性,又要满足当地严格的环保要求,排土场施工在生产过程中已成为整个露天矿山建设的重中之重。以厄瓜多尔米拉多铜矿首期排土场建设及使用为例,分别从排土场的排水、筑坝、排土方式、分层碾压、排土场维护等几个方面,详细阐述了多雨少石条件下露天金属矿山排土场建设的施工措施及方法,这些施工措施和方法在该矿山施工生产过程中已经得到了广泛的应用及推广,对同类型的矿山施工也将起到一定的指导作用。

The Construction Measures and Methods for Waste Dump of Open Pit Metal Mine in Hylaea Area of South America

The hylaea area of South America has a drippy climate and complicated geological condition. It is necessary to guarantee the stability of the waste dump and satisfy requirements of local strict environment protection during construction process of open pit metal mine. Thus， the waste dump construction has been the most significant during the construction of whole open pit mine. Taking the construction and usage of Stage1 waste dump in Mirador Copper Mine in Ecuador as a case， the construction measures and methods for waste dump of the open pit metal mine were elaborated from aspects of dewatering， damming， dumping ways， layered rolling， maintenance of waste dump under conditions of more raining and less rock. These construction measures and methods have been applied and generalized extensively during construction process of this mine， and also offer certain guidance to similar type of mines.
