Abstract: Mining is one of the most dangerous trades all over the world. In some countries, underground miners lack safety, social guarantees and in case of injury may be left to cope without assistance. There are negative social impacts as well, such as displacement and lost livelihoods. The mining industry has the highest incidence of occupational deaths among all industries. Common causes of occupational deaths include rock falls, fires, explosions, methane intoxication, and electrocution. There are many case studies behind underground mines, a recent case study in china reveals that underground mining in China is the world's deadliest industry. To overcome all these disasters, we have developed a better communication technology which has to be employed for an intelligent sensing and warning system. For this, RF technology is chosen for communication inside the mines. Safety is the most vital part of any type of industry. In the mining industry safety and security is a fundamental aspect of all. To avoid any types of accidents mining industry follows some basic precautions.Keyword: Vibration recognition, Smoke recognition, Bluetooth module, SMS Alert.
