摘要:本文通過收集貴州省天柱縣某重晶石礦礦床地質(zhì)、礦體特征及其傳統(tǒng)的地質(zhì)塊段估算資源量等勘查資料,結(jié)合固體礦產(chǎn)勘查信息系統(tǒng)(QuantyPES),采用克里格法重新估算礦區(qū)重晶石礦資源量。與傳統(tǒng)的資源量估算方法(地質(zhì)塊段法)相比,采用克里格法進(jìn)行資源量估算是準(zhǔn)確可靠的。

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.
Keywords: barite mine; 3D geological modeling; QuantyPES software; Kriging method; resource estimation; Tianzhu County
貴州省天柱縣一帶重晶石礦由海底熱液噴流沉積而成[1],由于其礦體呈層狀、似層狀產(chǎn)出,資源量估算主要采用傳統(tǒng)的地質(zhì)塊段法,該方法具有原理簡便、易于掌握、應(yīng)用廣泛、準(zhǔn)確可靠等優(yōu)點(diǎn)。(剩余3517字)
