Abstract Based on summarizing existing research status of mining-induced fractures developing features in overlying strata and engineering application domains of radon gas，geophysical and chemical properties of radon gas are applied attemptly to the field of mining engineering firstly；and the radioactive measurement method is introduced to detect the mining-induced fractures development process in overlying strata and its containing water quality in underground coal mining. Then，a comprehensive test system for detecting mining-induced fractures in overlying strata on surface with radon(CTSR) is independently developed，which has the advantages of installation-dismantlement facility，physical simulation model laying convenience and achieving fast two or three dimensional physical simulation experiment. The CTSR has been used to two-dimensional similar physical simulation for mining coalface 11203 of Daliuta coal mine in Shendong mining area，the dynamic evolution characteristics of mining-induced fractures in overlying strata and its corresponding law with radon concentration change have been obtained. Meanwhile，the feasibility of detecting mining-induced fractures in overlying strata on surface with radon also has been validated further in this experiment.
