| Abstract: | The paper introduced the present status of the wireless communication in China coal mines. The paper analyzed the existing technical problems, such as the mine roadway influenced to the wireless transmission, difficult to pick up the weak signals and noise interference in underground mine. The paper discussed the solutions for the mentioned problems. Also the solutions for mobile communication technology at surface ground can be fully to solve the wireless communication problems in underground mine. |
