Research on Safety Subregion Partition Method and Characterization for Coal Mine Ventilation System

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]...

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...

Research on Remote Condition Monitoring System in Coal Mine

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...
