Numerical analysis of static stability of a preventing infiltration layer in a fly ash storing site;

In the pastt,he aim to construct storing sites is to prevent the fly ash from entering the surrounding or polluting the running water.

Environmental geological problems of ash yard of fossil fuel power plant;

Through the analysis of the ash yard effluent in Qiangqing thermal power plant, and according to the position of the ash yard, an ash effluent and rain water treatment system has been designed.

This paper presents a kind of waterblowing fill technology to recover soil for reclamation in ash yard of power plant.

Seepage analysis of ash disposal area and further development technique of ANSYS;

Serious leakage occurred in the rock-faced dam for the ash disposal area in Yuelian Power Plant and endangered the safety ofthe dam.

A new technique of fly ash for sub dam,which is a new type dam for storage of fly ash produced by coal power station,is developed in valley fly ash field.

Based on several two dimensional seepage finite element calculations in ash field of thermal power plant,the main factors of seelage field have been summarised.

This paper makes analysis on the water resources conditions of the area of ash field of Xinlong Gangue Power Plant in Channgzhi City,and connecting with the situation OF local loose bed groundwater resources and karstic groundwater resources,this paper makes evaluation and analysis on the quality of the groundwater in this area.
