The mining-related damages due to the mining operations such as ground subsidence, tailing, Acid Mine Drainage, and soil contamination have a significant effect on our social and economical environment. So, for the effective prevention and reclamation works of the hazards in the mining area, the systematic management of mine information and mining-related damages is urgently needed. In this study, we estimated the possibilities of GIS-based system development for the mining area and related database. We classified the steps of building GIS as mine itself, mining-related damages, rehabilitation works and additional functions for estimating damages and analyzed the essential database and functions for each step. GIS will be helpful to estimate the mining-related damages and to carry out the reclamation works effectively.

Land was reclaimed at the waterfront in the Pluit area of Jakarta for a 90ha residential-cum-recreational development. The reclamation works involve construction of permanent and temporary dykes, fill placement, soil improvement, dredging of internal canals and marina, and construction of canal revetment. The site lies on 16m to 18m thick soft seabed deposits. Settlement of the reclaimed areas will result as a consequence of consolidation of the soft underlying sediments. In order to reduce post-construction settlement to within acceptable levels, a system of vertical drains and preloading was adopted. This paper describes the use of Fibredrain, a prefabricated vertical drain made of jute and coir fibres developed at the National University of Singapore, in the soil improvement works and a secondary use in the construction of perimeter dykes for the reclamation works. The construction of the perimeter dyke must be carried out in such a way that slope stability is on ensured. Bamboo rafts and bamboo clusters with Fibredrain inserted, and stage construction were employed to improve stability during the dyke formation for the Pantai Mutiara project.

In order primarily to establish the working stages in the reclamation works and to- analyze the working characteristics of man-power, the investigations for construction_ works were conducted on Echeon Largescale Reclamation Project Area. The results are summarized as follows; 1. The working chart on reclamation by man-power is Fig.IV-1. 2. The. ratio of actual working time to total varied with the total times, being 1.0 for less than 4 hours but about 0.9-0.83 for more than 5 hours. 3. Felling operations can be classified into three stages as truck-cutting, branch- cutting, and binding-up, of which results are in Table IV-2. The larger the diameter of stands, the more times for both the cutting operations are, but the moving time is constant to be about 15 sec. 4. Stumping and clearing works have the results prepared in Table IV-3. Between the stumping time and the diameter of stands d, there show highly significant positive correlations, expressed as t=2.212d -4.792. The more the ratio of small diameters to total, the more hastily the total hourly working results of each person are increased. 5. Working results for constructing drainage facilities and ridges are in Table IV-5. The labours for placing patches of grass are required more than twice or three times as much as those are showed in the established standards, and such the different results imply more investigation to be necessary. 6. Table IV-6 sholvs the results for plowing andh arrowing, that are less amount thant the standards. Therefore, more inverestigation should be prepared.

In 1980 the Ministrv of Agriculture, Forestry and Fisheies(MAFF) established the Long-term Tideland Development Scheme in the South-west Seashore Region. Since that time Korea has been developing comprehensive and innovative development frmaeworks in reclamation works and levelling up the potentialities of the donating country of internatioal cooperation in that field. And also, Korea has the well-organized governmental institutions for international cooperation in the development of tideland reclamation technologies such as RDC(Rural Development Corporation) for the field of agricultural engineering and RDA(Rural Development Administration) for the field of agricultural development. In Conclusion, it is ascertained that Korea has a good potentiality of aiding developing countries in the development of tideland reclamation, especially in agricultural development.

The objective of this study is to analize the system of legal compensation for the fishery loses caused by public works and to suggest alternatives on the current compensation system. Korea government has been performing reclamation activities in coastal region to conduct farm, urban and industrial area, and such activities are still going on in Yeongjongdo airport area, Saemangeum area and so on. Reclamation interrupts fishing activities in or around the reclaiming area, therefore, the compensation for fishery losses incurred by fishermen should be made. The system of legal compensation in Korea, however, is based on the land compensation, and the regulation of the compensation for fishery losses in the Fishery Act can not be applied for the compensation of public works because the procedure of the compensation in the Fishery Act is different from its cause of action. Therefore, this study is caried out to suggest a resonable compensation procedure and to provide a basis for establishing legal system.

광해방지사업은 인간의 과거 광산 활동과 현재의 삶(환경)과 밀접하게 관련되어 있다. 이는 광산지역이 국가적 관리가 필요한 이유 중 하나이다. 광해방지사업의 효율적 시행을 위해서는 폐광산 지하공간에 대한 정밀한 조사 및 분석이 필요하다. 한국광해관리공단은 지하공동을 실측하고 조사하는 실용화 기술을 개발해오고 있다. MIRECO EYE 시스템은 지하공동의 3차원 수치화 및 형상화 조사장비이다. 레이저, 소나 및 영상측정 기술이 융복합되어 있으며, 접근이 불가능하였던 지하공동에 대한 정보를 획득하고, 광산 지역의 침하 위험관리에 사용되고 있으며, 최근에는 도심지 싱크홀 분야 등 다양한 목적으로도 활용되고 있다. 본 연구는 MIRECO EYE 시스템을 통해 획득된 정밀 수치정보 및 형상정보의 분석에 관한 연구이다.

실트폰드는 크기가 55만평의 인공연못 안에 두께가 3~20m의 초연약점토가 침전되어 있었다. 1990년대 중반에 매립이 시작되었다. 매립 전 시료채취 및 다양한 종류의 원위치시험을 수행하였다. 실트폰드에 침전되어 있는 흙은 극도로 연약하기 때문에 모래 포설장비를 이용하여 모래를 전 지역에 균등하게 살포하였다. 대단히 주의 깊은 시공에도 불구하고 모래 포설시 대규모 전단파괴가 발생하였다. 따라서 파괴지역에 보강을 위하여 가로가 900m이고 세로가 700m인 고강도 보강매트를 포설한 후 재차 모래를 포설하여 매립을 완료하였다. 매립의 성공은 수중 콘관입시험으로 확인하였다.

In this study, the evaluation method of diffusion characteristics of Suspended Soli&SS) and the generation limit(source and thick) are investigated, which is significantly affecting on marine examined by construction works such as dredging and reclamation. Dispersion characteristics of SS is examined by hydraulic tests and numerical works in consideration with the Pusan Port. Hydraulic model test was performed in 2-D wave flume to find the limit wave conditon of re-suspension of solid as well as the time dependent characteristics of settlement The results obtainded in the study are as follows; 1) The quantituative evaluation af SS is the basic parameter of marine environmental impact assessment in related with the port development The SS increases as the water content of sea bed solid increases and the density decreases. 2) The sea bed solid in Sinsundai area, Pusan Port has the water content range of 83~157% 3) The ratio of suspension velocity against settlement velocity is about 0.25 and SS concentration converges as the wave heigh. 4) The SS increases 2 time when time step increases 3 time(10 sec to 30 sec) in numerical simulation It means that the effect of the time step should be checked in detail to stable. The diffusion The diffusion coefficient are Affiected senstively in the dispersion process while sea ved friction coefficinet have not strong relation in the simulated area

낙동강은 그 하구 근처에서 김해평야하고 부르는 델타지역을 형성하였다. 김해평야에 퇴적된 점성토는 다른 나라의 점토층에 비해 유달리 두껍다 (최대 60m). 이 지역의 일부는 새로운 공업단지의 개발을 위해 연직 배수재를 설치한 후 평균 5-7m의 높이로 매립하였다. 연약 지반 위에 매립작업을 수행하면서 침하량을 측정하였는데, 실측침하량은 이론적으로 예측한 침하량보다 현저히 크다는 것을 알게 되었다. 이 논문은 김해점토의 퇴적환경의 관점에서 과다침하가 발생되는 이유를 기술하고 있다.
