초록
국가의 지속적인 발전을 위해선 광물자원의 안정적인 확보가 중요하지만, 지표나 천부에 배태된자원은 점점 더 빨리 소진되고 있다. 따라서 심부 광물자원에 대한 관심이 높아지고 있다. 지표 지질정보나 시추 조사를 통해 지하 심부 광체의 형상을 예측하는 것은 상당히 어렵다. 물리탐사는 3차원의 지하 물성모델을 생성하며, 이러한 물성 모델은 심부 지하구조를 해석하는데 이용된다. 심부 지하구조 해석의 정확도를 향상하기 위해서는 물리탐사 뿐만 아니라 다양한 복합 지질 정보를 효과적으로 융합하고 해석해 내어야 한다. 이를 위해 디지털 트윈 기반 광물자원 탐사를 제안하고자 한다. 디지털 트윈 구축을 통해 물리탐사 결과를 포함한 다양한 복합 지질 정보를 하나의 플랫폼에 구축하고, 신뢰도 높은 통합 해석을 수행하며, 이를 기반으로 탐사 및 시추 조사에 대한 사전 시뮬레이션을 수행하여 각각의 탐사가 갖는 불확실성을 최소화하고 탐사 성공률을 높일 수 있을 것으로 기대한다
Abstract
Securing mineral resources is important for a country’s continuous development. As most shallow orebodies have already been mined, deep orebodies are targets for mineral exploration. It is difficult to predict the geometries of deep orebodies using geological and drilling data. Geophysical surveys provide three-dimensional (3D) physical models for the interpretation of deep underground structures. To improve interpretation accuracy, it is necessary to effectively integrate not only geophysical exploration but also various complex geological information. We propose a mineral exploration method based on a digital twin. Various types of complex geological information, including geophysical data, are integrated and built into the digital twin. Based on this, it is possible to enhance the reliability of interpretation and perform accurate simulations of exploration and drilling. With the use of a digital twin, we can expect that a stable integrated analysis can be performed to minimize the uncertainty of each exploration and increase the exploration success rate.
