The invention provides an opencast coal mine radioactive environment geology comprehensive investigation method, which comprises the following steps of carrying out environment gamma radiation dose rate, soil radon concentration and soil radon exhalation rate investigation in an opencast coal mine key area and a main influence area, and carrying out evaluation zoning; measuring the radon concentration in the air according to the investigation point where the environmental gamma radiation dose rate reaches the dangerous area and the investigation point where the soil radon concentration and therock-soil radon exhalation rate reach the severe dangerous area, carrying out long-term monitoring on the air radon standard exceeding point, and evaluating the rock-soil radionuclide content by adopting a radioactive rock-soil test sample; carrying out water environment and underground water radioactivity investigation in the peripheral area of the coal mine, including radioactive element-containing dust deposition and
