The industrial explosives in Korea have been made and used since 1952. The blasting accidents have increased gradually with the use of explosives. Based on the Police Department and Guns & Explosives Safety Technology Association's researching materials, the blasting accidents between 1988 and 1997 have been investigated and analyzed in this paper. FTA method was applied for the analysis of the blasting accidents which occurred in the tunnels, roads, subways, and various kinds of building construction area. The results show that the majority of the accidents, about 45.7% of the total, are due to the fly rocks. It is similar trend in Japan. The FTA analysis performed on the accidents by fly rocks shows that the major source of the accident is human factors such as non-observance of the safety rules, less knowledge of the safety and so on. The results of the study ate expected to provide basic data for making and observing the safety rules, making and amending the laws concerned and planning the security project. It will be helpful in preventing the blasting accidents and in reducing the loss of valuable lives and the financial damage.

This paper was reported on the seminar of Korean-Japanese professional engineers. The first of all, it was described the comparative rifle between Korea, Japan & USA on fatal accident on the construction works. Next, it was described that some accidents was occured in typical reason and it will help us to prevent the future accident.

This study is for analyzing the explosion accidents in the tunnels, roads, subways, streets and various kinds of building construction area with the use of Fault Tree Analysis(FTA). based on the police Department and Guns & Explosives Safety Technology Association's researching materials. the explosion accidents have been investigated and analyzed between 1988 and 1977. As the result, we can find out that the majority of the explosion accidents in Korea is the accidents by flown stones(45.7%), like in Japan. So we make the research chart which is needed for analyzing the explosion accident, and then analyze these accidents systematically. using the investigation codes of the industrial accidents. After that, the FTA was performed on the accidents by flown stones. They result fromm non-observance of the safety rules, and lees knowledge of the safety and so on. Moreover several causes are combined and then the accidents are apt to happen. So according to the results of this study, for the protection of the explosion accidents, the specialized safety education is badly needed and the enough investigation of the places before the work along with the management for safety in working must be planned.

The specific characters in recent Chemical processing and industrial plants are the handling of severe limit conditions such as high pressure, high and low temperature, high speed production and transportation plant automation and appearance of many new hazardous materials in numbers and quantity. The possibilities of these characters causing the accident and environmental pollution in industrial activities become very high. This paper describes the concrete policy In prevent the explosion accident out of the many accidents which are the safety of the safety engineering.

This study is concerned with the disasters that occure in the field of industrial explosives and analyzed by two side the disaster of the manufacturing factory and that of the field, and is studied about the safety and the countermeasure. The industrial explosives accidents occure just accidentaly and unforeseeable, and reappearance experiments are more difficult. The 3E of J.H. Harvey was applied in this study to establish the counter measure of preventation of accidents, overcoming these restricted factores. As a method of technical safety countermeasures. The blasting vibration formula which had been conformed from the Seoul Subway Construction work during 1980-1984 year, was uilized, and, using the formula $V=Kw^{0.5}D^{-1.5}$ for the gneiss which is widely distributed in Pusan area, an index of the minimum and maximum amount of gun powder, to be used according to safety distance was made, and it helped the gun powder managing technician's practical business. During the fore work discharging, the safety distances of felling were theoretically established based on the writer ${\diagdown}s$ experiences of more than 10 years on this field.

A survey for understanding the opinion about the safety and economy of different types of detonators used in domestic tunnel construction was carried out for total 345 people in related areas. From the result, it was found that 86.7% of the surveyed people felt non-electric detonator was safe. From the experimental points that the cost of detonators is in charge of 8.1% in overall tunnel blasting cost, and the utilization of non-electric detonators will also contribute to the prevention of blasting accidents by the electrical safety, this study can help providing opinions and basic data collected from related areas to manufacturing companies, police department, and companies ordering tunnel construction.

NATM as method of tunneling has been applied to construction of domestic subway, roads, rail way, water way etc. Accordingly, we have NATM's many drafts and constructional results, but many problems and accidents have occurred under construction of tunnel using NATM for shortage of technical data. Poorness of constructional improvement, systemic inconsistency etc. Especially, everyone was shocked at Gupo's train wrecking accident lately. The purpose of this thesis is presentation of means for setting technical problems, by looking into Gupo's train wrecking accident and home records that applying NATM in tunneling failed, to minimize future safety accidents we find that the general problems of home fifteen sites having occured accidents is badly geological survey, nonconfirmationi of base rock's state, formal measuring management, shortage of specialists, systemical discrepancy and that disregarding NATM's rules makes general problems. The results of this study are Summarised as follows : 1. We advise repletion of design standards to practice crosshole test for confirming connected rock base on vertical section of tunnel. 2. We advise to practice pre0boring and pre-grouting for a weak layer difficult in applying NATM. 3. We advise systemic improvements that field servicer can construct tunnel of his own free will considering base rock's state at tunnel . 4. We advise that specialist, who can make a conduct and supervise above mentioned items as well as measuring management, should be posted at field.

Explosive blasting performance is composed of charging, tamping and connecting performance, which need lots of power and time. Thus, operator's inconvenience and muscle load are increased by their pose. Then it's unavoidable for one to make a human error. As a result, blasting accidents and disasters of explosives may happen. So we need to have systematic study. According to their pose's changing we have OWAS, RULA, REBA, OSHA, ISI, NLE, TVAV, BLUE-X. In this article, OWAS, RULA, REBA have been evaluated. As a result of this research, it is shown that work-related musciloskeletal disorders are related to the second accident's happening.

Explosion involving rapid energy diffusion are causing enormous human and economic damage. Due to the advancement of the industry, various and widespread explosion accidents are occurring worldwise, and to prevent such explosion accidents, accurate cause analysis should be the basis. Research analysis related to worldwise explosion accidents was carried out in a limited range for some accidents. By conducting bibliometric analysis of keywords on all the papers published in international journals, this study attempted to derive the overall research trend by period and the latest fields in which future researchers may be interested. As a result of the study of keywords, the number of papers was generally small and the number of overall key words was small from 2005 to 2014, but numerical simulation and artificial intelligence have been used for the analysis of explosion accident cases since 2015, and various studies such as lithium-ion battery and mixed gas, which are the latest research fields, are currently being actively conducted.
