기존의 수맥탐사는 탐사지역에 정확한 좌표 값을 입력하기 위해서 많은 시간과 인력이 동원되었다. 본 논문에서 제시하는 시스템은 수맥 탐사자가 한 명으로 구성되어 단지 수맥 측정장비를 가지고 탐색할 위치 영역 내에서 움직이면 GPS에서 현재 위치를 산출해서 지자기장 값을 PDA에 데이터베이스화하여 저장하도록 되어 있다. 가로와 세로의 폭이 500M의 영역에서 인원 3명이 동원되어 작업한 결과 12시간정도 시간이 소요되었다. 그러나 본 시스템으로 한 명의 인원을 이용하여 측정한 결과 불과 40분 정도로 시간이 많이 절약됨을 알 수 있다.

This paper presents system to enable an efficient water vein detection using GPS and geomagnetic fields. Because the developed system in this paper can be automatically saved the data acquired from GPS and geomagenetic instrument into the database, it can decrease the number of detectors and save the time for water vein detection. The developed system can analyze the positions for the drilling correctly.

Because of numerous mountain region, agricultural affairs work can't be done without groundwater in Kangwon Do area. Especially to improve high mountain area vegetable quality and raise income offarmers, both of groundwater and hydrothermal system to keep adequate temperature in hot and coldseason have to be developed. Domestic groundwater was developed for the use of agricultural watersince 1960. Exact investigation and control of groundwater are greatly required in utilizing undergroundspace as subway, nuclear power plant, oil and hazardous waste storehouse. Groundwater contaminationowing to industrial irrigation, trash decomposition can have a serious effect on human health and rustof underground building. In this study, global prospecting system are applied to detect groundwater, using electrical, seismic and georadar prospecting method.

The water leakage of reservoir embankment usually occurs around channelling pipes, which gives little influence on the embankment in a normal state. However, the embankment can be destroyed when the water level of reservoir increases with heavy rain and the rainy season in summer. Investigating the water vein and its path is therefore very important from the viewpoint of disaster prevention and embankment maintenance. The water leakage in dams and levees where the channelling pipes are working as weak zone was analyzed by using both numerical simulation and experimental method in this study. To detect the water leakage, an electrical resistivity survey was used and investigated for its' usability. The numerical results show the size and location of weak zone increases the importance of selection of electrode spacing. The leakage experiments of model embankment present the best result is obtained under the conditions of electrode spacing of 0.3m and dipole-dipole array. By studying the water leakage in dams and levees, the electrical resistivity survey is observed it is a very useful method to predict the leakage.

Jinsan gold deposit is a hydrothermal vein type deposit consisting of several fissure filling quartz veins developed within the Changri Formation of the Ogcheon Supergroup in Geumsan, Chungnam. This study is to provide an efficient exploration and development strategies based on the characteristics of the geology, geological structure, core logging, and ore vein occurrence and grade for the four pits (New pit, Main pit, Yanghapan pit and Teugho pit). Quartz veins are mostly developed with the strike of $N10^{\circ}-25^{\circ}W$ and $N5^{\circ}-20^{\circ}E$, and the thickness is in the range of 0.1~0.5 m, sometimes extending to over 1m. Although the quartz veins commonly form massive shape, they sometimes show zonal structure, comb structure as well as brecciated texture. Major ore minerals are pyrite and chalcopyrite, and pyrrhotite, sphalerite, galena, marcasite, electrum and chalcocite are also accompanied as minor phases. Gray and milky white quartz veins, which are occasionally crosscut by calcite vein, also include fluorite. Ore evaluations for the 22 samples revealed that the samples from the pits generally have very low Au contents, lower than 1 g/t, but some clay samples of drilled core show very high Au concentrations, up to 141 g/t, indicating that Au content is much higher within fault gouges rather than within fresh quartz veins. This may represent that gold might have been reworked and reprecipitated by hydrothermal fluids in association with reactivation of the faults, and thus suggest that ore occurrence in this deposit is very complex and irregular and therefore more precise and systematic exploration is required.
