Application of technology combined GIS and transient electromagnetic technique in coal mine water burst prevention — A case of Sihe Coal mine

Transient Electromagnetic Method (TEM) has the characters with sensitivity to water body, high resolution and less influence from topography. Geographic Information System (GIS) has the characters with powerful geospatial analytics, modeling and visualization. Measured data surveyed with TEM are loaded into ArcGIS, then multi-feature overlaid with the panel water-rich distribution map. Three-dimensional distribution of rich water was obtained. And then the water yield, water rich zone in front of roadway can be analyzed. The application of this technique in west area of Sihe Colliery was proved that this method was one effective methods in detecting the rich water distribution and range around mining and tunnelling face. And more the analytical results was visual. Reliable basis of prediction and prevention water burst was obtained.
