The invention provides a method for early warning of dangerous sources of a
coal mine, and belongs to early warning methods for
coal mines. Identification of the dangerous sources, evaluation of risk levels of the dangerous sources and monitoring of the dangerous sources are carried out through a
coal mine dangerous source
early warning system; dangerous source information which comes from different places, is of different levels and is not reviewed or is not qualified during review are dynamically broadcasted with an electronic mine figure as a background at a
computer terminal in a
local area network, a coal mine dispatching room and a
wellhead large-size screen terminal, wherein the dangerous sources of different early warning levels are expressed with different colors; places having a great influence on coal
mine safety production are provided with a
wireless sensor network, information of the dangerous sources of the places are monitored in real time, related functional offices arrange to rectify and reform dangerous source specific information which happens but is not found or which is found but cannot be typed in a
system timely and manually or which cannot be timely displayed on
terminal equipment of the dispatching room or
terminal equipment of a
wellhead large-size screen, and coal
mine safety production is guaranteed. The method is used for coal
mine safety management and achieves look-ahead and timely precontrol and management for hidden dangers and accidents happening in the coal mine possibly.
