A comprehensive analysis method for automatic pre-alarming of coal mine

For problems that existing integrated automation system of coal mine could not trace to source of failure warning and checked failure causes difficultly, a comprehensive analysis method for automatic pre-alarming of coal mine was proposed. The method, which is based on accident-causing theory, takes forward and backward inference of failure warning information of the integrated automation system through constructing abnormal event correlating graph, so as to check primordial cause of the abnormal event and forecast other events caused by the abnormal event. The method realizes linkage monitoring of correlative information of abnormal event.
