Abstract: In view of current situations that there was no effective management of gas geological data in coal mine enterprises and gas geological maps were updated hardly with low utilization, an establishment scheme of intelligent pre-warning platform of mine gas geology were proposed from gas geology pre-alarming principle, database establishment, platform structure, function models, key technologies, pre-alarming guarantee mechanism, etc. In the platform, GIS technology is used to build spatial database of gas geology, so as to manage relative gas geological data intensively and effectively and update gas geological maps automatically. WCF technology is used for data sharing of relative gas geological maps in different graph platforms. Based on gas geology theory, a set of integrated pre-warning index system of gas geology is established, which is for real-timely pre-warning gas geology through comprehensively analyzing gas occurrence, geological structure and coal-seam occurrence in front of working face. Application shows that each pre-alarming result of the platform accords with measuring result in filed with good effect.
