In order to minimize the impact on the structure during an internal explosion, the explosives storage must be kept at a distance from the inner wall to prevent the sympathetic detonation of the others explosives in an unexpected explosion. For safe explosives storage, a gap test was conducted by simulating the split arrangement of explosives inside the storage. In this study, the separation distance and arrangement between the emulsion explosives were applied differently to be sympathetic detonation at 2D of diameter and non-detonated at 2.5D. Considering the coefficient of detonation transmission and the size of the explosives storage, the explosive amount of 3kg was set, and most of the gap tests according to various arrangement changes were non-detonated, and safety was confirmed when applying the batch.

It was described Several Tuneling method for applying petrolum oil storage. The most Important factor of Tunneling is not only reinforcing works such as pre-grouting and after grouting but also rock bolting and shotcrete. The efficent works should be done by professional skillman, and also the classification of rock should be decided by professional engineers.

To review the appropriateness of current regulations on the simple explosive storage facility, the effects of internal explosion on the structural stability of the standard storage facility were analyzed by means of both FEM analyses and field experiments. As a result, it was found that the explosion-proof performance of the existing storage structure was not sufficient for 15 kg of emulsion-type explosive. Thus, an alternative method of splitting explosives was tested by conducting sympathetic detonation experiments. This method worked properly as expected, and the proper amount of splitted explosive was determined according to the test results. In addition, a storage structure with open ceiling was found to be very effective because explosion pressure was released so rapidly that the damage of the facility could be reduced significantly. Hence, such a structural pattern was proposed as a new design scheme for simple explosive storage facility.

The overall management for explosives in domestic and regulation for blasting is managed by the control Act of guns, sword, explosives etc. On the details for handling and method, delivery, storage, use and management for explosives and work safety for the accident prevention is recommended to the related business site through Standard safety work guideline of blasting which set by safety & health 27 Act handling. In this study, It reviews the standard safety work guideline of blasting notified by Ministry of employment & labor. We propose the new products introduced into domestic explosives market, definition of explosives word when the newest blasting technology is revised, emulsion explosives, bulk explosives and electronic detonators which increased in the latest. Indeed, We propose a typical handling method of non-electric detonator and electronic in order to make the renewed Standard safety work guideline of Blasting on work guideline.

Army guns, swords, and explosives are substances that remain in danger and are expected to suffer significant damage in the event of an accident. Therefore, considerable attention is needed to handle them. Safety management of army guns, swords, and explosives can be classified into manufacturing, storage, and transportation, among which transportation is essential for performance tests and contract delivery. In 2020, the number of army guns, swords, and explosives transport increased by 30% compared to 2014, which can be seen as an increase in the demand for the transportation of army guns, swords, and explosives by defense companies due to defense improvement projects. Meanwhile, social interest in explosives safety management and social demands for strengthening safety management are increasing due to the explosions of explosive plants. Therefore, it is necessary to look at the status of safety management. This study examined the safety management for the transportation of army guns, swords, and explosives in the united states and domestic private sector. This paper presents improvements to safely and efficiently transport army guns, swords, and explosives.

This study Is to summarize the contents for the investigation and design of the construction for oil storage. Since underground caverns are large scale, in their construction one should consider the mechanical stability of cave·rns and the economic view of construction. On the basis of them, cavern's section and layout were determined and water curtains were designed to maintain hydraulic equilibrium so that gases were sealed tightly. Also the supporting criteria for rock bolt and stotcrete were determined by means of the classification of rock masses and the results of finite element method. The criteria of grouting reinforcement were presented according to the results of injection test in the pilot holes of working face.
