15 صفحه اولKnowledge-Enhanced CO-monitoring in Coal-Mines
Detection of underground res is an important security task in hard-coal mining. Automated re detection systems are usually based on the monitoring of carbon monoxide (CO). Systems using conventional technology based on threshold and tendency observations, however, generate a large number of false alarms. We show how CO-concentrations can be forecast by appropriate models of the physical and che...
متن کاملSurvey paper on Fire Detection techniques in Coal mines
Fire accidents inside the mine are one of the most horrifying disasters in the mining industrial field. It causes the number of casualties of the miners and the wastage of the valuable natural resources. It is the prime and primitive requirement to find out some technique or process to predict the possibility of fire so that the causes could be prevented for which the conditions of the broke ou...
متن کاملCoal Mines Monitoring and Security System
Based on continuous revolution of coal mining technology,this paper puts forward a project about safety monitoring system of coal mine using Zigbee technology and RS485 interface. A system is designed using group of sensors which monitors the different environmental condition in underground mines and if value exceeds from threshold value, then the Miners are informed through Alarm. Another modu...
