This paper deals with the issue of safety inside underground mines. The safety system designed based on wireless sensor network. The position of the different sensors inside underground mines is set by using analysis with ANSYS software. The safety system modeling in this paper is cost effective, energy saver , consistent, uninterrupted. This system performs automatic monitoring of different useful parameters inside underground mines required for the safety of the mine personals. Transmission of data to the base station is done by using Zigbee technology. This total scheme concept may be implemented with necessary modification in multiplex, hospital, shopping mall etc.
