This paper briefly introduces 3D-seismic exploration,electrical prospecting,hydrogeological exploration for designing and producing of coal mine as well as the result of its application.

According to the result of electrical prospecting,the Pb-Zn ores in Daheishan,Xiaoshuihe and Hulugou in Xunyang region,Shaanxi Province is evaluated.

The application of electric prospecting method to the reconnaissance survey of gold deposit;

The example of electric prospecting used in the metallic mineral resources prospecting.;

During the research process of Gansu Province 2005 annual research project "Applicable research of electromagnetic imaging system in coal geological exploration",put forward a set of method to raise electric prospecting resolution and accuracy of interpretation-apparent longitudinal conductance imaging method.

Driver circuit of transmitter for electrical exploration based on IPM;

Data acquisition,signal processing and calculating in electrical exploration have been finished in DSP.

Some new requirements,such as communicating with GPS and PC,have been proposed to the transmitter for electrical exploration.

A surface fitting algorithm application based on weighted average in electric exploration;

Through electric exploration, the fissure-developed zone, water-rich area and water gushing position were located.

The instrument was developed from the high density electric method and had modified the data collection operate mode of the tradition electric exploration equipment.
