New integrated monitoring and control system for disaster gas application in coal mine

An Integrated Image Clarity Method for Coal Mine Safety Monitoring

According to the poor image quality of the monitoring system in coal mine monitoring, an integrated image clarity method was presented which using adaptive multi-level noise reduction median filter based on the direction in the spatial domain to denoise the image first, then using multi-wavelet transform to enhance the low-light image in the transform domain. This integrated approach combines t...

Coal Mine Safety Monitoring System Using ARM9

Coal is mined in every country which is mainly used to generate electricity. Thousands of mine workers were killed every year due to many disasters takes place inside coal mine. These accidents are caused mainly due to the leakage of poisonous gas [2] present in the mine. Especially developing countries face a poor safety system for mine workers. Hence it requires a safety monitoring system [1]...

Estimation of coal seams gas content for evaluating potential use of methane drainage system in Tabas coal mine

Methane gas emission, accumulation, and explosion are the most important risk factors in underground coal mines. Hence, having a knowledge of methane gas emission potential in underground coal mines is of crucial importance in preventing the explosion risk, loss of life, and property, and providing miners' safety. The purpose of this work is to provide the prediction maps for the C1, C2, and B2...

Research of Intelligent Gas Detecting System for Coal Mine

According to statistic data of China in recent years, gas explosion accounted for above 70% in all coal mine accidents. Frequent gas explosion accidents have caused great losses of lives and property. Therefore gas detection and monitoring system is needed to serve as a safety device in coal production. In this paper, an intelligent gas detecting system is designed. This detection instrument ad...
