The invention discloses a through-the-earth communication equipment time service method based on a Beidou system, and the method employs a Beidou time service module and a clock maintaining signal of a ground through-the-earth communication system, and employs ground-underground through-the-earth transmission to transmit the Beidou time service information to through-the-earth communication equipment in an underground pipe gallery sealed environment. High-precision and high-stability time service of an underground sealed environment equipment system clock is realized; through-the-earth time service signal transmission rate and transmission time determination is provided, and through-the-earth time service signal error correction values and an implementation method are provided. According to the through-the-earth communication equipment time service method, the time service information is transmitted to through-the-earth communication equipment and the like in the closed and sealed environment of the undergrou
