초록 This research is to provide appropriate safety measures on each operating coal mines which are designated as a sustainable coal mine. Two coal mines were chosen in this project year, Do Gye coal mine of Dae Han Coal Corporation and Tae Mack Coal mine which is one of private coal mines. The remarkable aspects these mines and their counter measures are as follows; 1.Do Gye coal mine * There are spontaneous gases in coal seams. Therefore, specially designed mining methods has to be provided and attention must be payed to gas control.* Underground water in-rush in central region makes it worse to work with. These water supposed to come from the neighbouring closed mines. The appropriate counter measures has to be provided as soon as possible. * The complicated transportation system pushes up production cost. Centralization of working faces and hauling system is desirable. * A new mining method has to be developed for mining mildly inclined seam which gradually become flat as getting deeper. * Slope of waste dump seems to be unsafe. A necessary measures for acquiring slope stability and moving up the villages at downstream must be taken. 2.Tae Mack Coal mine * The complicated roadways makes the ventilation network uneffective. An appropriate measures for closing abandoned roadways has to be taken so that the air leakage can be protected. * Mined out area of pocket type deposit makes the surface to subside and induce water in flow through the crushed zone. An appropriate water drainage ditches on the subsided area is requested.* As the vertical span of caving method is as high as 50 meters, volume of water in-rush is remarkable. To reduce water in-rush in the working area, the alternative mining methods such as sublevel caving will be considerable. * The main haulage system is not sufficient. Over whole review of the transportation system must be carried out. For acquiring effective safety, all the requested matters mentioned above has to be realized and the morale of the workers has to be encouraged as well
