ULTRA SONIC RANGE FINDING FOR DISTANCE MEASURING IN COAL MINING

Sneha Punia, Ramandeep Singh

Abstract: Measuring distances has always been a challenge in coal mines as it involves a lot of risks and disturbances. One method to measure the distances without any hindrances in sensitive places like coal mines is via Ultra Sonic waves which generates 40 KHz sound pulse that travels with the speed of sound to the object and returns it echo that helps in calculating the distance, which further display on the LCD display. The medium required here is air medium. This project performs the distance measuring techniques, required in coal mines. This technique is proven to be very helpful in places where human reach is not possible or difficult.
