In this paper ,the home and abroad present conditions in construction and research of refuge chamber about underground mine have been summarized systematically .The existing problems in the construction of refuge chamber have been analyzed ,such as the inadequate construction scale and relative quantity of refuge chamber ,the limited radiations cope of refuge chamber ,poor accessibility and the invalidity of escape routes .The importance of refuge chamber system has been put forward .In order to improve safety capacity of refuge chamber system ,the total size ,number and the location distribution of refuge chamber should be reasonably determined .And what’ s more , the more escape routes leading to refuge chamber should be set up .%本文系统地总结了国内外避难硐室的建设现状，剖析了避难硐室建设中存在建设规模和相对数量不足、安全功能的辐射范围有限、逃生路线的可靠性较差等问题，提出了构建避难硐室系统的概念，即合理地确定避难硐室的总规模、数量及其位置分布，并设置多条通往避难硐室的逃生路线，提高避难硐室系统的安全辐射能力。
