Study of deep mining safety control decision making system

More and more coal mines have been turning mining into deep well. Geological environment is complicated and the safety issues are becoming increasingly conspicuous. To realize informationization, intellectualization and visualization of mining safety and high-efficient mining decision, a deep mining safety control decision making system based on Longruan GIS is developed. The system not only fulfills three-dimensional (3D) visualization on geological information such as coal seams, strata, boreholes, crustal stress, gas and water distribution, but also realizes 3D visualization on surveying information such as shafts, roadways and working faces. Moreover, the system stores, queries, computes and analyses various geomechanical parameters which closely associate with safety control decision making, and provides a visual, simple and high-efficient software tool for deep well mining under high crustal stress, high gas thickness as well as high seepage water pressure conditions.
