  • Advanced geological surveys and exploration activities were first carried out in Korea in 1884 in accordance with a treaty of friendship and commerce between Great Britain and Korea and a treaty of friendship and commerce between Germany and Korea. The first paper by Gottsche, C. was also published in a German Journal in 1886. Efforts toward independent acquisition of Western geological survey and exploration technology were actively promoted by the Korean Empire in the early 1900s, but were frustrated by the Japanese Empire. Systematic geological surveys and exploration were conducted in Korea by Japanese geologists during the Japanese occupation. A basic geological maps(61sheets), a bulletin on the geological survey of Korea, a bulletin and technical report on deposits in Korea, and a coalfield geological survey report were published during this period. Overall, the intentions under lying the geological surveys and exploration activities by foreigners in Korea prior to the Japanese occupation were questionable. However, the results of these surveys and explorations themselves can be evaluated as positive in terms of academic performance.

  • Geological heritages can be defined conveniently as geological records worthy of conservation, and are represented in most cases by geological outcrops. So survey and evaluation of geologic outcrops are necessary for better conservation of geological heritages. As a measure to prevent potential destruction of geological heritages from various development projects, I propose construction of database based on survey and evaluation forms of geological outcrop, which can also be used for environmental impact assessment. The geological survey form consists of survey area, category, subcategory, location, dimension, geologic features, photo, description, and investigator. The evaluation form consists of evaluation category, detailed evaluation, comprehensive evaluation, and evaluation grade. The evaluation category is divided into academic aspect, education effect and landscape. The detailed evaluation items for academic aspects and education effect are representativeness, rarity, diversity and typicality, while those for geomorphology and landscape are peculiarity, aesthetics and naturalness. The evaluation grades are divided into five, where the first grade means a must of conservation.

  • Face mapping during tunnel construction is useful and critical to predict the characteristics and stability condition of following tunneling sections and to select optimum support pattern. Therefore, a detailed geological survey of the tunnel faces, as important as a routine underground survey and a RMR evaluation, should provide critical information of the tunnel face condition in terms of the engineering geological condition and the safety of working environment for the following tunneling section. But the results of the face investigation have not been applied satisfactorily during tunneling due to limitation of technique, experience and time. This study analyze problems of face mapping in tunnel construction site by using statistical results of face mapping sheets obtained from completed tunnels, and suggest several opinions to improve face mapping during tunnel construction.

  • To develop site characterization technologies for a radioactive waste disposal research in KAERI, the geological and hydrogeological investigations have been carried out since 1997. In 2006, the KURT (KAERI Underground Research Tunnel) was constructed to study a solute migration, a microbiology and an engineered barrier system as well as deeply to understand geological environments in in-situ condition. This study is performed as one of the site characterization works around KURT. Several investigations such as a lineament analysis, a borehole/tunnel survey, a geophyscial survey and logging in borehole, were used to construct the geological model. As a result, the geological model is constructed, which includes the lithological model and geo-structural model in this study. Moreover, from the results of the in-situ hydraulic tests, the hydrogeological properties of elements in geological model were evaluated.

  • The achievements of Tateiwa Iwao's work in Korea are assessed as follows. Firstly, he pioneered the practice of stratigraphy in the Korean peninsula and completed geological maps of 21 sheets at 1:50,000 scale. Secondly, he published the results of a geological survey as bulletins, technical reports, and papers. Thirdly, he faithfully carried out the handover of assets and research outputs to Korea. Finally, after returning to Japan, Tateiwa wrote a book entitled The Korea-Japanese Tectonic Zone: History of a Geological Survey in Korea. However, he neglected to educate and train the next geologists for conducting geological surveys and exploration in Korea.

  • 댐의 항구적인 안전을 담보하기 위해서는 댐 구조물 자체가 안전하여야 함은 물론 댐 구조물의 기초를 이루는 지반이 충분한 차수성과 내하성을 가져야 하므로 이들의 특성을 규명하기 위한 지질조사는 매우 중요하다. 댐 지질조사의 목적은 댐의 기초지반, 댐 체 축조를 위한 재료원 및 저수지 주변지반 등에 대한 지질학적 특성을 파악하고, 댐의 설계와 시공에 필요한 지질공학적 제반 성질을 상세히 파악하는데 있다. (중략)

  • 세계 각국은 지속가능한 지하수자원의 사용을 위해 지하수의 부존, 유동 및 수질특성을 파악하는 지하수조사를 수행하고 이를 기초로 수문지질도를 작성하고 있다. 이에 인터넷 검색을 통해 세계 192개국의 수문지질도의 작성현황에 대한 자료를 수집하였다. 국가규모의 수문지질도는 91개국, 지역규모 정밀수문지질도는 57개국의 제작하고 있는 것으로 파악되었다(검색을 통해 확인되지 않은 국가라고 하여도 제작을 하지 않는다는 의미는 아님). 또한 제작 시기별로는 러시아가 1930년에 가장 일찍 수문지질도를 작성하였으며 우리나라는 1990년 전북고창을 시작으로 2011년 100개시군구의 정밀수문도 작성이 계획되어 있다. 세계의 주요한 대부분의 나라는 시기에 차이는 있지만 수리지질(지하수)조사를 실시하여 수문지질도를 작성하고 있으며 최근에는 대부분 지질조사소(Geological Survey)가 조사 및 제작을 담당하고 있다. 지하수 조사내용과 수문지질도 작성 scale은 각국의 수리지질학적 조건에 따라 다르며 그에 따른 주제도 내용도 조금씩 다르다. 또한 지하수 이용 여건 및 수리지질학적 환경변화에 따라 일정주기로 반복 조사하고 있는 것으로 파악되었다.
