Wireless sensor nodes have the advantages of low-cost, easy deployment and mobility. If they are deployed underground mine, with the existing underground cable transmission systems, wireless sensor network can improve the mine information greatly. The paper is to find the relationship between signal quality/packets loss rate and distance by the test in coal mine. The result can be as a reference for deployment of wireless sensor networks in coal mines.
