地下採掘에 따른 鑛害防止對策에 關한 硏究 = A Study on the prevention of mine damage resulting from underground exploitation

다국어 초록 (Multilingual Abstract)

Due to rapid increase in production of coal and other mineral resources in the nation, the underground mining below the local drainage level will be proceeded and the underground spaces and the length of gangways and branches will also be increased accordingly.
Subsequently, damages by the mining operations, Such as, Surface subsidences, waste water treatments, etc, became public problems. Especially the surface subsidence problem became the most serious problem in underground mining operations. The purpose of this paper is to find the adequate methods to prevent and to minimize those damages, due to mining operations and to maintain the effective industrial operation, by observing the damages which comes in various ways and by planning the methods which will eliminate such damages.
