江西矿山接替资源勘查找矿进展及体会

Prospecting progress in succeeding mineral resources of old non-ferrous metals mines in Jiangxi and experiences

列举浒坑等老矿山深部找矿成效、小东坑老点新评经验和金山式金矿找矿模式应用实例,简要介绍老矿山和成矿区带找矿选区体会。老矿山找矿从编制矿山地质工作程度图入手,开展矿山立体填图,进行含矿地质体定位预测,"探边、摸底、攻深、找盲、综查",就矿找矿。成矿区带找矿跟踪地矿动态选区,物化探覆盖圈靶位,追索控矿容矿地质体、示矿地质体找矿探矿,老点新评,快速突破。

The paper briefly introduces the experience of selecting prospective targets within old non - ferrous metals mines and metallogenic belts in Jiangxi illustrated by practical application examples of the prospecting achievement at depth of Hukeng mine, re - evaluation of prospected area at Xiaodongkeng deposit area, and the application of exploration model for the Jinshan type gold deposit. The prospecting procedures within the old mines follows the following steps： starting from compiling geologic exploration level in the mines, conducting three dimensional mapping of the mine, and predicting spatial distribution of ore - bearing geologic bodies, i. e. , ＂prospecting the surrounding areas of the mine, the depth of geologic body, exploring the hiding orebodies, and conducting comprehen- sive assessment＂ and prospecting orebodies in the known old mines. For the exploration in the metallogenic belts, the dynamic follow - up of the regional exploration activities will be carried out to select the prospective districts, where the geophysical and geochemical a- nomalies occur, follow the ore - controlling and ore - bearing geologic bodies and indicated mineralization information in the targeted ar- eas. Meanwhile, conduct the re - evaluation of old prospecting areas based on the new clues and exploration models in order to achieve the quick exploration achievement.
