(5)Grouting result:The surplus inflow of water in the grouting beds is less than 6 m 3/h which has been designed,the rate of exclusion of water is above 98%.
The recharge conditions of pit,lithologic characters and occurrence of the surrounding rocks of ores,system of mining of ore deposit and the parameters of calculated formulas should be main effect factors for predicting the pit inflow of water.
The paper deals with basic thought and method of prediction of water inflow into tunnel by fuzzy clustering theory, and presents main factors infuencing water inflow and their quantized formulae. The water inflow is estimated at 1.0 to 3.0 m~3/d·m, taking Qinling extra-long tunnel as an example, which tallies basically with the measured water inflow of 2.07 m~3/d·m. This shows the reasonableness of the prediction method.
Based on Euclidean distance, applied in water detection by electrical sounding,The gradient K method can estimate the location of the well and its flowing yield with measured data, and can obtain satisfactory geologic results.
Analysis on the factors affecting the flow of water by introducing the difference between the two alluvial deposit faces ,1327 and 1422,and prediction is given to the faces of 1325 and 1421.
It is suggested that hatching time is determined not solely by increased internal pressure caused by inflow of water and salts, but also by some unknown internal factor.
Flow perturbation due to inflow of water (mainly rain water) and loss of wastewater from the pipes of a sewage network is a widely recognized phenomenon in the operation of sewage transfer systems.
A numerical finite element model called SEEP/W was used to predict the inflow of water and to calculate the height of the seepage face in and around the pit.
A new highly sensitive and rapidly responding gravimetric method was used for the investigation of rapid responses manifesting in water inflow and outflow from roots in the intact seedlings of tomato Lycopersicon esculentumMill.
Time dependences of local filtration coefficients averaged over the area and their spatial variation during the flow of water and aqueous electrolyte solutions were studied on soil samples of undisturbed structure using tracer method.
The results of an experimental investigation into the hydrodynamic stability of a flow of water carried out on a rigid surface in a hydrodynamical test-bed of low turbulence by the tellurium method are presented.
A study is made of the stability of the plane-parallel convective flow of water in a plane vertical layer bounded by planes heated to different temperatures in the region of anomalous thermal expansion.
Investigations were made of the influence of polyacrylamide additives on the change in the relative permeabilities for the simultaneous flow of water and a nonpolar hydrocarbon liquid.
