Forecasting water inflow of mine working face concerned with separated strata seeper;

Chaotic time series analysis and prediction for mine water inflow;

The calculate methods comparison of the predictive of tunnel discharge rate;

Combined with project example,it researches the deep well water-jet theory,defines the number,separation and well depth of the well point canal through the discharge rate calculation,introduces the well point water-jet construction of deep well detailed,and discusses the problems existed and corresponding treatment measures in the act water-jet process,which will assure the trouble-free project.

On purpose to know the water burst quantity of coal 3 in Dongtan mine, the authors give an approximate calculation method, by changing unsteady flow model to steady flow one to calculate the steady discharge.

In Wangjiazhai Coal Mine,the discharge is mainly controlled by precipitation.

It can be used to evaluate the water storage in bearing media in the tunnel project by using the discharge of the bore hole or fracture.

An analysis of the karst ground collapse and water yieldof the Zhongliangshan Tunnel in the Yusui Expressway;

Forecast of Hydraulic Discharge Based on Grey Neural Network Inseries Peg Model

By using Visual Modflow software,the numerical simulation is carried out,and the seepage field characteristics and the hydraulic discharge of dock foundation pit of different confined drainage scheme is simulatively calculated in several typical conditions,finally hydraulic discharge of foundation pit obtained accords with actual situation;also,the design schemes .
