Abstract： This paper introduces the basic situation of geological disposal repository of high-level radioactive waste， and discusses the research status of harmful factors produced in the process of roadway excavation of high-level radioactive waste geological disposal storehouse. According to the three harmful factors of blasting smoke， dust and radon， which are mainly produced in the process of roadway driving， this paper introduces the diffusion law of harmful factors in the process of tunneling， and puts forward the corresponding countermeasures from different angles. According to the current research situation， the deficiencies of the current research are proposed.

Keywords： geological disposal repository of high-level radioactive waste; tunneling; dust; blasting smoke; countermeasure

高放废物具有半衰期长、放射性强、毒性大等特点，对环境的危害较大，目前可行的做法是深地质处置，核心是采用“多重屏障”有效包容和阻滞核素，使其对人类和环境不会造成无法接受的影响。（剩余5867字）
