In order to realize the mine water source identification and to prevent water accidents, taking Xinglong Zhuang coal mine’s lower group coal mining as an example, based on the analysis of mine hydrogeological conditions, the mine water source identification system was designed by using the software of MapObjects powerful spatial analysis ability and Bayesian classification analytical method. The software can achieve mine water source identification and provide a certain basis for mine water disaster prevention and control.

Water Disaster

In the eastern mining area of Ningxia, China, multi-layered sandstone aquifers are widely distributed in the underground. However, the water abundance of these aquifers is not clear, which brings great challenges to the prevention and control of mine water disaster. In this paper, five mining areas in eastern Ningxia were taken as the study area, and the distribution characteristics of aquifer and the mine water filling source were analyzed through the analysis of geological data and numerical simulation. Finally, the lithology influencing index (LII) was constructed, and the water abundance of the aquifer was evaluated. The results show that the sandstone aquifer III in the lower part of the Jurassic Zhiluo formation is the main water-source aquifer of the #2 coal seam in the study area, while the middle aquifer II and the upper aquifer I are indirect water-source aquifers; the areas with extremely strong and strong water abundance are Maiduoshan, Hongliu, the south of Shicaocun, southeast and southwest of Meihuajing, and the central and southern areas of Shuangma mining areas; when the depth of water drainage boreholes in the roof reaches the development height of the water-conducting fracture zone, the pre-drainage measures can effectively control the mining inrush water of the working face and ensure the safety production. This research is of great significance to the prevention and control of mine water disaster.

Some coal seams belong to cretaceous strata in the east of Inner Mongolia, China. There are obvious differences of rock characteristics and mechanical properties between Cretaceous and Carboniferous- Permian strata. The overburden failure characteristics of extra-thick coal seam with slicing full-mechanized caving mining are studied through rock mechanics experiment, field observation and theoretical analysis and so on. Water disaster prevention and control method of roof and goaf is put forward under the condition of extra-thick coal seam with slicing full-mechanized caving mining. The final research results include: (1) The rock of cretaceous strata has low strength and soft characteristic, its stability is very poor, cretaceous rock belongs to weak type; (2) Under the condition of extra-thick coal seam with slicing full-mechanized caving mining, the ratio between caving zone and mining height of field observation result is 4.58～4.74, the observation results of two boreholes are close; (3) It is significantly effective to prevent and control water disaster from goaf through roof hole drainage method, coal and rock safety pillar remain method is used to limit mining height under the Tertiary gravel aquifer, which makes the working face exploit safely.

Water Disaster

Based on present condition analysis of coal mine water disaster occurred in recent ten years, classification bases such as water source, water passage, water disaster form, economic loss and casualties caused, aging characteristics and spatial distribution relationship between coal seam and water source of the disaster are proposed. According to water sources, the disaster can be subdivided into natural and artificial source coal mine water one. According to water passage, coal mine water disaster can be subdivided into natural and artificial passage one. According to the spatial distribution relationship, it can be subdivided into roof, periphery and floor water inrush disaster. According to damage form, the disaster can be subdivided into normal temperature, abnormal temperature and corrosive one. Based on economic loss and casualties, the disaster can be subdivided into general, larger, great and special great coal mine water disaster. And according to aging characteristics, it can be subdivided into instant, hysteretic, gradual and skipping coal mine water disaster. Finally, typical characteristics of each disaster are analyzed preliminarily.

Water Disaster

In China, water disaster often occurred in coal mines in recent years. According to official statistics on coal mine water accidents occurred in recent twelve years in China, major characteristics of the water disaster have been illustrated. The result shows that the number of both water accidents and corresponding fatalities decreased from 2001 to 2012. And apparently, the accidents occurred in township-owned coal mines and triggered by gob area water accounted for a higher proportion, respectively.
