초록

광물자원 개발에서 자원탐사는 지표와 지하에 있는 경제성 있는 광물을 찾아내는 작업으로 개발, 생산단계에 비해 성공률이 낮은 실정이며, 탐사를 통해 많은 자료를 수집하고 수집된 정보를 정확하게 분석하는 것이 필요하다. 본 연구에서는 3D 레이저스캐너를 이용하여 광산공간정보를 구축하고, 정확도 평가를 수행하여 X, Y 및 Z 방향으로 최대 0.140m와 평균 0.095m의 편차를 얻어 3D 레이저스캐너를 통한 광산공간정보 구축의 활용 가능성을 제시할 수 있었다. 또한 자원탐사 결과를 이용해 광체구간에 보간법을 적용하여 광체 모델링을 수행하였다. 광체 모델링 결과는 3D 레이저스캐너를 통해 구축된 광산공간정보의 모델링 결과와 중첩하여 정밀 광산공간정보 기반의 광체 모델링 결과를 구축할 수 있었다. 연구를 통해 구축된 광산공간정보 기반의 광체 모델링 결과는 자료해석의 용이성과 산출자료의 정확도를 높일 수 있어 향후 광물자원 개발과 광해방지 분야 관련 업무의 효율성을 크게 증가시킬 것이다.

In mineral resource development, resource exploration is a task to find economical minerals on the surface and underground, and the success rate is low compared to the development and production stages, and it is necessary to collect a lot of data through exploration and accurately analyze the collected information. In this study, mine spatial information was constructed using a 3D (Three-dimensional) laser scanner, and accuracy evaluation was performed to obtain a maximum deviation of 0.140 m and an average of 0.095 m in the X, Y and Z directions, and the possibility of utilizing the construction of mine geospatial information through a 3D laser scanner could be presented. In addition, the ore body modeling was performed by applying the interpolation method of the ore body section using the resource exploration results. The ore body modeling result was superimposed with the modeling result of the mine geospatial information built through the 3D laser scanner to construct the ore body modeling result based on the precise mine geospatial information. The results of ore body modeling based on mine geospatial information built through research can increase the ease of data interpretation and the accuracy of the calculated data, which will greatly increase the efficiency of work related to mineral resource development and mine damage prevention in the future.
