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]...
متن کاملGlobal Trends in Coal Mine Horizontal Stress Measurements
Knowledge of in situ stresses is fundamental to many studies in earth sciences, and coal mine ground control is no exception. During the past 20 years, it has become clear that horizontal stress is a critical factor affecting roof stability in underground coal mines. The theory of plate tectonics and the World Stress Map (WSM) project has been extremely helpful in explaining the sources and the...

متن کاملsDEVELOPMENT OF COAL MINE SAFETY SYSTEM USING WIRELESS SENSOR NETWORKS
In this work, a system is proposed for safe Coal Mine Monitoring, which plays an important role in coal mine safe production. Wi th continuous enlarging of exploiting areas and extension of depth in coal mine, many laneways become monitoring blind areas, wh ere are lots of hidden dangers. It is very difficult to lay cables which are not reliable and not effective. For to overcome this , a new s...
متن کاملMarginal Discriminant Projection for Coal Mine Safety Data Dimensionality Reduction
Marginal Fisher Analysis (MFA) is a novel dimensionality reduction algorithm. However, the two nearest neighborhood parameters are difficult to select when constructing graphs. In this paper, we propose a nonparametric method called Marginal Discriminant Projection (MDP) which can solves the problem of parameters selection in MFA. Experiment on several benchmark datasets demonstrated the effect...
