Dhagat, Diksha A. Srivastav, Neha Y. Fulzele, Arati P.Bondre, Atharva U. Kulkarni DBACER, Nagpur, Maharashtra, India ABSTRACT In this paper we are implementing surveillance, safety measures for mine workers which is most essential in underground mining areas/sections. Here we are presenting MEMS based sensors network used to monitor the environment parameters of underground mine area and sends all sensed parameters/data to the PLC( Programmable Logic Controller). Gas sensor is used to detect the gas found underground. The vibration sensor is used to detect the vibrations .Vibration above a particular level would be assumed as a problem in the mine which would actuate the lift and provide timely help to the workers. Keywords : Sensors Network, PLC, Gas Sensor, Vibration Sensor I. INTRODUCTION Safety of person is primary concern/aspect in any industry, especially in undergrounding mining industry. To avoid any type of unwanted phenomena, all mining industry follows some basic precaution and phenomena. In underground coal mine major of accidents occurred are based on fire and natural gas and overheating of surroundings. We are also considering the health condition of a person using Fall-Detector, made of MEMS-Accelerometer (ADXL335). Coal mine safety monitoring system based on wireless sensor network can timely and accurately reflect dynamic situation of staff in the underground regions to ground computer system. The hybrid underpass radio propagation model comprising of the free space propagation and the modified waveguide propagation is proposed. However, using popular radio communication inside underground mines has some drawbacks. While radio signals are transmitted, attenuation, diffraction, multi-path and scattering are frequently very serious. Thus, wireless communication is the important need today for the fast, flexible safety, accurate and production method in underground mines. There are different other research ideas proposed by different people on wireless communication. In a network called chain-type wireless underground mine sensor network (CWUMSN) is recently proposed which consists of three kinds of sensor nodes: sensing nodes, cluster head nodes, and a base station deployed on both sides of the tunnel at regular intervals to monitor the underground environment and locate the miners. A new decision- making approach to coal and gas outburst prediction with multisensory information fusion is proposed. This system is design by considering all these parameters i.e. it can sense temperature, pressure, humidity, Fire, Gas as well as Persons Fall. Therefore the designed system is giving a very good solution for most of the problems faced in mine accidents. A good communication system must be set between mine workers and Remote Base Station For this wired network communication is inefficient in underground mining areas. So we are choosing a wireless network system based on RF communication at 2.4 GHz (CC2500 RF Module is a Trans-Receiver module which provides easy to use RF communication at 2.4 GHz.) And GSM networks for sending SMS to fire and Ambulance. II. METHODS AND MATERIAL The proposed system is divided into two segments. First is a hardware circuit that will be attached with the body of the Mine Workers. It may be preferably fitted with
