ABSTRACT

Safety is the most vital part of any type of industry. Negligence in the safety part may cause damaging of high-quality equipment hampering of production or may cause loss of human life also in extreme cases. In the mining industry, safety is a fundamental aspect of all. To avoid any types of unwanted phenomena all mining industry follows some basic precaution and phenomena. Communication is the most vital key factor today, to monitor different parameters continuously and to take necessary actions accordingly to avoid any types of hazards related to safety, production, security or managing of human resources.

To avoid loss of material and damaging of human health, security and safety system as well as reliable continuous faithful communication system is essential in the interior of the underground mines. To enhance security, safety and productivity in underground mines, a reliable communication system must be established between workers, working in the mine and a fixed base station. The communication network must not be interrupted at any moment and at any condition. Inside underground mines, the wired communication network system is not so effective.

Nowadays, coal miners suffer a lot from accidents in coal mines due to the complexity of mining environment. The number of accidents in coal mining is increasing day by day. There are many dangers in every mine. Environmental parameters are monitored to protect those who work in the mines. Miners are more susceptible to a variety of threats, including gas explosions, gas leakages, fire and severe changes in temperature and humidity. This project describes the monitoring system for coal mines using IoT module Wi-Fi. The module is equipped with a network of sensors such as a humidity sensor, gas sensors (for harmful gases), a temperature sensor, vibration sensor and the data from these sensors can be reliably transmitted using Wi-Fi. Most mining accidents are caused by slow data transmission, long range and loss in transmission. This problem can be solved with this wireless communication technology. The system uses a range of sensors all controlled by an Arduino controller in order to achieve this task and send the same to the Wi-Fi app through IoT module interfaced to the Arduino controller.

The project designed with Arduino Microcontroller is aimed to acquire the data of different parameters related to the coal mine. The set values can be programmed in the controller, for example temperature, when the temperature is exceeded more than the set value, immediately the controller activates the buzzer or the alarm. Likewise, the MQ 2 is used to sense the harmful gases, DHT 11 sensor for Temperature and Humidity measurement, vibration sensor for any explosions or earth quakes. All the parameters are continuously monitored, processed by the controller and simultaneously sends the same information to the android mobile Wi-Fi app through the Wi-Fi modem interfaced to the controller.

When any of the parameter goes abnormal, automatically buzzer will be activated and the information will be transmitted using Wi-Fi module. The required power supply for the entire module to operate is directly derived from the mains single phase supply. As we are using Wi-Fi module, the project work falls under the topic of IoT. IoT refers to the infrastructure of connected physical devices which is growing at a rapid rate as huge number of devices and objects are getting associated to the Internet. Weather monitoring is a very useful application of IoT and we are using it to upload the parameters values to an app. The system will inform the authorized persons about any abnormal parameters when found by sending a notification to the user. After the user gets the notification, he can take the necessary actions.

An Android application is to be downloaded in the android device and connection with the Wi-Fi module is to be established to intimate the alerts from the controllers about the inputs, thereby reducing the manual process of monitoring. Wi-Fi (Short for Wireless Fidelity) is a wireless technology that uses radio frequency to transmit data through the air. Wi-Fi has initial speeds of 1mbps to 2mbps. Wi-Fi transmits data in the frequency band of 2.4 GHz. It implements the concept of frequency division multiplexing technology.
