Application Analysis of TD-SCDMA Technology in Coal Industry

The paper analyzed development requirements of communication system of coal mine in China and existed problems of main communication technologies of coal mine at present, and proposed a scheme of wireless communication system of integration of underground and surface based on TD-SCDMA. It introduced networking structure and functions of the system. The test result showed that the system can seamlessly cover underground operation area, surface dispatching control area and living area, which not only can meet with communication requirements of safety production but also realize command and dispatching under special situation.
