大厂锌铜矿地质特征及探矿工程设计思路

大厂锌铜矿是近年来铜坑矿危机矿山找矿项目取得的新成果.对矿体地质特征进行详细研究后,在首采区探矿设计时,选择一个主要中段布置坑探工程,在勘探线巷道上布置坑内上下钻孔,这种设计可以控制矿体的空间形态,又大大减少了掘进量,相应地减少了土地的占用,降低了地质灾害和环境污染,经过两年来的勘探验证,这种设计思路在今后深部探矿中值得借鉴.

Geological characteristics of Dachang zinc-copper orebody and the design thinking of exploration engineering

Dachang zinc-copper orebody is the new found orebody of prospecting in Tongkeng mine in recent years.After the study of geological characteristics,the major sublevel is chosen to layout the exploring engineering in the design for the exploration of the first mining area,and drill holes both in the top and the bottom of the channel.This design thinking can not only control the space shape of orebody,but also reduce the digging works,decrease the land occupation,lower the geological disaster and lessen the pollution of environment.More than two years practice proves that it is effective and can be used in other similar situations.
