露天矿设计的一个主要问题就是确定露天矿境界及计算矿岩量。确定了露天矿境界,可据以确定生产规模,选择采运设备、采矿方法和开拓方法,确定企业的服务年限,编制采掘进度计划,确定工人定员以及企业的技术经济指标。解决这个问题的原始资料见矿床的地质勘探报告,包括地表地形图、地质纵、横剖面图、矿体构造图、围岩特性、矿床的水文地质条件以及矿区的气候条件。
One of the main problems in the design of open pit mines is determining the open pit realm and calculating the amount of ore. Determine the open-pit mine realm, according to which to determine the scale of production, selection of mining equipment and mining methods and pioneering methods to determine the service life of enterprises, the preparation of mining schedule, determine the workers and enterprises technical and economic indicators. The original information on this problem can be found in the geological prospecting report of the deposit, including topographic maps of the earth’s surface, vertical and horizontal sections of the geology, structural maps of the ore body, characteristics of the surrounding rock, hydrogeological conditions of the deposit and climatic conditions in the mine area.
