Abstract: According to the importance of the mine roadway heading through in underground mine to the mine construction and mine safety production, an early wa rning system of the mine roadway heading through was developed based on the WebGIS technology and the B/S framework. The mine roadway heading through plan an d heading through information would be dynamically displayed on the vector diagram with the WebGIS technology.The alarm information could be sent to the user's mo bile phone with the short messages and thus the technical means could be provided to timely master the mine roadway heading through information.The paper introduc ed the framework and function of the system and the applications in the mining area of Shenhua Group.The paper provided the distance early warning model, the midlin e early warning model and the waist line early warning model of the mine roadway heading through and the early warning index system.The standard heading through i nformation management and the optimized management procedure were realized and could provide the protection to the safety of the mine roadway heading through o perations.
