鱼儿山V6脉坑钻联合探矿技术研究

Research of joint drilling and adits Technology in V6 Vein, Yuershan

摘要:

湖南省沅陵县沃溪矿区危矿项目ZK9103、ZK7304孔揭露到鱼儿山V1脉底部V6蚀变层位，为缓解鱼儿山资源开采危机，运用地表立钻和坑内立钻相结合的探矿手段先控制V6脉主要工业矿体推测资源量、赋存平面位置与标高，再结合现有坑探工程现状，布置坑内反斜井+底板穿脉大巷+顺层底板斜井进行深部开拓与沿脉坑探工程探明和扩大可开发资源储量，达到了很好的探矿效果，延长了鱼儿山矿山服务年限。并建议在十六棚公、红岩溪、粟家溪等矿段的相应勘探线扩展探矿，进一步扩大底部V6盲脉的资源找矿前景。

Abstract:

In the dangerous mine project of Woxi mining area in Hunan Province, ZK9103 and ZK7304 reveal the V6 alteration layer at the bottom of Yuershan mineral vein V1. In order to alleviate the crisis of resource exploitation of Yuershan, the prospecting method combined vertical drilling at the surface and in the tunnel is used at the first to predict the resource amount of main industrial ore bodies and the position & elevation of occurrence plane, then according to the present tunnel engineering status, the inclined shaft in opposite direction to coal seam in the tunnel + laneway through the mineral vein bottom + inclined shaft bedding floor are arranged to carry out the deep development work and expand the reserves of resources for development. Good prospecting effect is received, and by which, the service life of Yuershan mine is prolonged. It is suggested to expand the exploration line in Shiliupenggong, Hongyanxi and Lijiaxi and some other ore blocks, so as to further expand the prospecting potential of V6 blind vein at the bottom.
