山东省莱州市东姜家矿区饰面用花岗岩矿荒料率计算方法浅析

Primary Study on Block Yield Calculation Method of Ornament Granite in Dongjiangjia Mining Area in Laizhou City of Shandong Province

摘要:

荒料率是评价饰面用花岗岩矿的一个重要指标，它分为实际荒料率和理论荒料率两种。实际荒料率能反映矿体的实际情况，对矿山评价准确性高。但这一资料获得的费用大、工期长。而理论荒料率是在节理、裂隙素描图上布裁理论荒料后计算得出的。以山东省莱州市东姜家矿区饰面用花岗岩矿为例，就如何使理论荒料率比较真实地反映矿体的实际情况并指导生产作简要探讨。

Abstract:

Block yield is an important indicator of evaluating ornament granite mine. It can be divided into actual block yield and theoretical block yield. The actual block yield can reflect the actual situation of the ore bodies and has highaccuracy evaluation for the mine. But data obtaining cost a lot and need long time. The theoretical block yield is calculated after cutting theoretical stone block on sketch of joints and fractures. Taking Dongjiangjia mining area in Laizhou city of Shandong Province as an example, a brief discussion has been made on how to make the theoretical block yield factually reflect the actual situation of the ore bodies and guide production.
