Geophysical control system of radiation-hygienic coal quality, to be mined by open method

Consideration is given to the system of geophysical control of radiation-hygienic quality of Urtuisky brow-coal deposit coal, created in Priargunsky industrial mine-chemical association. Coal of the above-mentioned deposit is characterized by high content of natural radionuclides. The system is noted for monitoring of natural radionuclide level in initial coal and in products of its burning at all stages of technological process of mining, transportation and utilization of fuel, with the use of gamma methods (logging, sampling, rapid analysis
