A dynamic simulation displays system on the digital mine about the flooded roadways range
The paper researched mine roadway connection relation and affection of the flooded roadways range by water inrush value and water inrush site.The paper described the calculation theory and the dynamic display means of the water level changes in each roadway during mine flood period.The paper used the reconfiguration roadway connected graph way,separated the roadway of undulate up and down into several straight lines length.Each roadway length was turned into one way lean roadway length in the roadway connected graph.And it put the gob area and the discarded roadway in the roadway system that had the hydraulic power touch with them.This settled the foundation of calculating and displaying the water level.The article defined the node capacity and the water level cut set,and gave their computational method.It discovered the law that every roadway water level had same rising velocity in a water level cut set,and the course of a mine submerged by water inrush was the course of a series of water level cut sets to be inundated one by one.The paper gave the change rule of the flooded roadways range at all time with surely water inrush intensity,completed the imitation calculation about the flooded roadways range during mine flood period.The paper made use of truly three dimensions digital mine roadway system as display terrace.By means of calculating the rising velocity of the water levels in each roadway,using information integration and transfer technique,the paper achieved the one by one correspondence topology relationship between digital mine and actual mine.And the dynamic range of flooded roadways was timely displayed on the digital mine.By the resolution of the shortest time circuit,the paper found the optimum avoiding disaster course from any place in the mine to surface of the earth,obtained dynamic simulation display of an avoiding disaster course.
