为了多快好省地开发矿业,许多矿区正充分利用各方面的有利条件,实行露天开采.对于分布广泛的鞍山式铁矿来说,尤其是这样.实践经验证明,露天开采的矿区,只有考虑到开采方法的特点,合理地安排地质勘探工作,才能适应矿山设计、建设和生产对地质资料的需要.一、关于矿体边界的圈定在露天开采的矿区,矿体边界必须用勘探工程具体控制,取得工业储量,而不应当是推断的远景储量,这与井下开采的矿山是不同的.矿体边界的准确程度,直接关系到露天矿的开采境界线的合理确定,因而也影响到
In order to develop the mining industry more quickly and economically, many mines are making full use of all aspects of favorable conditions for open-pit mining, especially for the widely distributed Anshan-type iron ore.Practical experience has shown that opencast mining can only be considered To the characteristics of mining methods, reasonable arrangements for geological exploration in order to adapt to mine design, construction and production of geological data needs.On the ore body boundary delineation in open pit mining, ore body boundary must be controlled by the exploration project specific , And obtain industrial reserves, rather than inferred prospective reserves, which is different from mines mined underground.The accuracy of the ore body boundary is directly related to the reasonable determination of the mining boundary of open-pit mines and thus also affects
