Dù đang đối phó với giai đoạn khủng hoảng, than vẫn là tài nguyên năng lượng chưa thể thay thế. Tuy nhiên, than là nguồn tài nguyên không tái tạo, như vậy ngoài việc mở rộng tìm kiếm, việc khai thác hợp lý các mỏ hiện có là thách thức cho việc tìm kiếm thăm dò và khai thác. Sự phát triển của mô hình địa chất ba chiều (3D) liên quan đến việc tích hợp lượng lớn dữ liệu địa chất như thạch học, cấu trúc, địa hóa, địa vật lý và thiết đồ lỗ khoan, dễ dàng truy cập và bổ sung tài liệu. | Journal of Mining and Earth Sciences Vol. 62 Issue 5a 2021 119 - 127 119 3D Integrated geological modeling for coalbed estimation in the Khe Cham I mine Quang Ninh province Techniques and Applications Hung The Khuong 1 Minh Tu Ngoc Trinh 2 1 Faculty of Geoscience and Geoengineering Hanoi University of Mining and Geology Vietnam 2 Vinacomin Khe Cham Coal Company Cam Pha Quang Ninh Vietnam ARTICLE INFO ABSTRACT Article history Despite the crisis period coals are still an irreplaceable energy resource. Received 24th July 2021 However it is a non-renewable resource so in addition to expanding the search Accepted 24th Aug. 2021 the rational exploitation of the existing fields is a challenge for coalfield Available online 01st Dec. 2021 exploration and production. Incorporating large quantities of public geological Keywords data and proprietary lithological structural geochemical geophysical and 3-D Integrated Geological diamond drill hole data is needed to produce robust 3D geological models. It Coalbeds shows how reliable 3D maps can be used as immersive instruments for mineral deposit discovery this paper. The evaluation of coal reserves has been done by Khe Cham I mine 3D application on the Surfer and Rockwork software. The result of 70 145 Modeling thousand tons of coal for the V12 and V13-1 coalbeds of Khe Cham I mine is a Quang Ninh province. relatively consistent result with previous calculations. Therefore 3D analysis of the Khe Cham I mine shows a better visualization of the coal reserves and the spatial distribution of the geological formations in the site. Evaluating the correlation between the thickness and dip angle of the V12 and V13-1 coalbeds shows that the total mechanized coal reserves of the mine are mostly concentrated in the coalbeds of the dip angle below 180 accounting for and coalbed thickness from m. Moreover the application of 3D geological modeling for coalbeds in the Khe Cham I mine gives a rather intuitive and .
