Wireless Monitoring and Safety System for Underground Coal Mines Using Zigbee
Abstract
Safety of a person is primary concern in any industry especially in underground coal mining industry. Today safety of miners is a major challenge. Miner’s health and life is vulnerable to several critical issues, which includes not only the working environment, but also the prolonged effect of it. Mining activities release harmful and toxic gases in turn exposing the associated workers into the danger of survival. This puts a lot of pressure on the mining industry. To increase the productivity and reduce the cost of mining along with consideration of the safety of workers, an innovative approach is required. Communication plays an important role in surveillance and safety for any industries especially in underground coal mining industry. There is a need to develop active communication network in underground mine to quickly detect the underground environmental conditions and accurately provide necessary instruction to mine worker to evacuate if any danger occur. Underground communication is required to monitor underground parameter such as temperature, humidity, toxic gas etc. and take necessary actions accordingly to avoid any types of hazard. In this paper a design is proposed which is made of different sensors which will senses the environmental parameter in underground mines and this parameter data is send to the control room using wireless communication protocol zigbee. Zigbee is cost effective wireless communication protocol useful for wireless transmission of data. A whole design is placed on a robot which is wireless operated by remote control. Due to use of wireless robot, it will reduce the human intervention in security system and will improve the safety. So this report proposed a low cost zigbee based wireless monitoring system of underground coal mine placed on robot for better safety in underground coal mine.
