Abstract. Biogas reactors are a huge technical and technological installation that operates mainly as a result of the solar heat on earth and serves to produce biogas, but in areas where air temperatures are meant to vary (although in Uzbekistan, where there are four seasons), sunlight cannot heat the bioreactor enough during 12 months. Therefore, for the purpose of producing and storing biogas, the drilling hole's diameter is as wide as possible (1600-2000 mm), and the depth of the drilling hole is calculated normally (based on geothermic conditions) for the formation of biogas We drill wells of up to 1700 to 2500 m and strengthen the side walls through special preservation and build a biogas storage and harvesting reactor.The geothermal gradient of the underground does not depend on the sharp change in weather on earth based on its depth, so enough temperatures (+30o, +40o) to produce biogas are provided by selecting the required depth for biomass.The difference and advantage of technology over other types of bioreactors is: the length of service life of the wells produced, the low human factor in the course of the process, and the low likelihood of problems resulting from external influences in the environment, as well as one of the most positive indicators of it, is that the process of biogas separation does not slow down due to the likelihood of cooling air.
