Based on the science idea of coupling, this paper studied systematically the theory, mathematical model and technology of rock mass hydraulics in coal mining above aquifer, the numerical simulation method, the resemble simulation theory and method. A series of reciprocity law on the stress and displacement of upper and down floor of coal layer, coal pole, fault and the law of water pressure variety was analyzed thoroughly and particularly. Based on the relation of hydraulics character of multi-aquifer, the inspecting and predicting theory model, method and system of water outburst was founded. By used in the colliery, The results were ratified by colliery missionary. In situ test for the hydraulics character of the floor on hydrology observation hole was done.

Jianghan plain, located in the middle-south of Hubei province. Its ground water resources degree of development and utilization are high. The primary exploitation layers are the upside pore confined aquifer and the underpart cranny and pore confined aquifer. With the rapidly development of urbanization and economic,the water consumption is increasing.That have coused the local ground water table decent.In someplace,the excessive exploitation have induced the groundwater table fall and collapse.
