In this paper, integrated analysis was made on the mechanism of sudden water inrush and the relevant geologic factors, geologic structure, hydrologic geology, the source of filled water and water channels according to the water inrush event occurred in Shanghe Mining Area, the reason of sudden water inrush was the result of mutual action of both geologic conditions and engineering factors.
Based on the analysis of hydrologic geology and boundary conditions of the study area,Visual modflow model was recognized using actual measurement data,and the groundwater resources of the study area was evaluated.
Because of the complexity of the condition of groundwater dynamic force, aiming at the specific hydrologic geology condition, dynamic force condition, the pollutant migration instance of groundwater, establishing reasonable groundwater solute migration model, using computer languages, numerical simulating and visualizing the distributing State, is a cheap and effective method for predicting and preventing groundwater pollution.
The reservoir forming mechanism of Pingluoba Xiang 2 gas pool is analysed in the aspects of sedimentary structure development,pore evolution,oil-gas migration history,trap type and features,reservoir geological model,captock's performance,hydrologic geology condition etc.
Finally,the papersummarizes the application condition of stability evaluation of engineering geology and hydrographic geology of different kinds of landslides by geophysical exploration method andmakes evaluation on its practicality,economy,existing problem and development.
Among the factors the magma tic rocks geological structure, hydrographic geology, adjoining rock are more important, This paper describes the features of these factors and their influence on coal bed gas.
In this paper, the problems with environmental engineering geology and en-vironmental hydrographic geology caused by massive ground water exploitation are comprehensively 'discussed from the viewpoint of environmental geotechnics, these problems include surface subsidence and collapse, water resource shortage, water quality pollution and seawater intrusion, and the comprehensive measures for solving these problems are proposed.
Unsteady problems concerning the displacement of gas and oil deposits in a seepage flow of stratal water are of specific interest to oil and gas hydrogeology, and in the planning and analysis of the processes of reservoir exploitation.
The results of analytical studies of the problems arising in connection with the prediction of ground water flow in civil engineering, hydrogeology and irrigation engineering are reviewed.
Formulation of the inverse coefficient problems of hydrogeology
From the point of view of geomorphology and hydrogeology, we distinguish the two different spatial concepts between "the basin of Dongting Lake" and "the Dongting Basin".
Eight spatial structure types are determined through morphology, hydrogeology, hydrology and impulse response in karst districts, with the well studied Houzhai subterranean stream in Puding, Guizhou Province as a sample research area.
