Based on the situation of the mine geology disasters, Five kinds can be divided. The mine geology disasters’ model can be constructed by the grey theory in order to predict the loss of the recent years’. Then the model of the fuzz mathematic can be found to distinct the distribution of different area and to predict the area of may occur geology disasters. This way takes not only the law of the occurring of the mine geology disasters in count but also the difference of the different area. The results of this evaluation are more precise than before.

To improve coal preparation technology and increase output, a coal preparation plant in Shanxi province will ameliorate its present yield techniques by block-based coal preparation technology; involve structure reinforcement and alteration of the plant. The thesis deeply studies the design of structure reinforcement and alteration for the multi-floor reinforced concrete plant, reveals means and essential of the design. According criterions, practice experience and actual engineering characteristic, the thesis discusses reinforcement methods and detail drawing.

Based on EJB3.0,this article design and realize the distributed mine spatial data synchronization system, and integrate with LRGIS 3.0 to take mining engineering plane diagram for example, guarantee the consistency and timeliness of mine spatial data,and realize the mine informatization integrated with LRGIS 3.0。
