摘要:本文通过收集贵州省天柱县某重晶石矿矿床地质、矿体特征及其传统的地质块段估算资源量等勘查资料,结合固体矿产勘查信息系统(QuantyPES),采用克里格法重新估算矿区重晶石矿资源量。与传统的资源量估算方法(地质块段法)相比,采用克里格法进行资源量估算是准确可靠的。

Abstract: By collecting the deposit geology and ore body characteristics of a barite mine in Tianzhu County, Guizhou Province, as well as the traditional geological block estimation resources and other exploration data, combined with the solid mineral exploration information system (QuantyPES), this paper uses the Kriging method to re-estimate the barite ore resources in the mining area. Compared with the traditional resource estimation method (geological block method), the Kriging method is accurate and reliable for resource estimation.

贵州省天柱县一带重晶石矿由海底热液喷流沉积而成[1],由于其矿体呈层状、似层状产出,资源量估算主要采用传统的地质块段法,该方法具有原理简便、易于掌握、应用广泛、准确可靠等优点。(剩余3517字)
