The International Conference on Explosives and Blasting （ICEB） is a symposiumfor scientific and technical update on all aspects of explosives and blasting amongChina， Japan and Korea. From 2006 to 2011， The ICEB has been convened annu-ally for six times， alternatively in China， Japan and Korea， serving the blastingcommunity from the three countries with an excellent combination of scientific ad-vances and practical applications. In order to improve the quality of papers andfurther promote the development of the conference， the organizing committee de-cided to hold the ICEB once every two years since 2011.The 7th ICEB is organized by China Society of Engineering Blasting. The top-ics covered in this edition are wide-ranging fromrockmasscharacterizationandfragmentation， blast design and implementation， demolition blasting， underwaterblasting， special blasting， blastinstrumentation， blastingmonitoring，tosafetyandenvironment.This symposium has attracted wide attention and support from these three coun-tries. The number of papers received this time is 43， far more than that of anyprevious ICEBs. After the rigorous review of abstracts and papers， 33 papers （ 18from China， 5 from Japan and 10 from Korea） are accepted for publication and 28papers are recommended to be presented at this symposium. Papers to be presen-ted are mainly on four aspects， blast design & modeling， blast instrumentation，demolition blasting and blast monitoring， safety & environment.We would like to express our hearty thanks to the members of the China-Japan-Korea Technical Committee of Explosives and Blasting for their help and coopera-tion， and to the members of the national organizing committee for their critical re-view of all the submissions. We ~annot hold the event successfully without thegenerous financial support and the active cooperation of Zhuhai Society of Engi-neering Blasting， and the hard work of Metallurgical Industry Press. We sincerelywish the 7th ICEB a big success！
