Established in the 1980's, the SD method has been widely used in reserve calculation because of its combination of dynamic fractal geometry and structural geological variable theory. Reserve calculation is complicated due to mineral intergrowth. Compared with traditional methods used in copper polymetallic mine reserve calculation, the SD method shows better performance.

Geochemistry ore-forming elements association is an important indicator of ore deposit.In this paper, we adopt JADE algorithm based on the theory of independent component analysis to analyze the character of geochemistry mineralized element association, which discussed the combination anomaly from the point of view of Nonlinearity. It has been applied in Dongga gold deposit point in Tibet and good results were obtained.

According to the requirement of real-time detection system towards acquisition, storage and display of video data, a design method of video acquisition system based on FPGA is put forward. With FPGA as its core controller, the design presents a simplified video acquisition system to achieve standard video images. The design elaborately illustrates key points of video acquisition system, thus the acquisition, storage and display function of real-time video can be technically realized. In the end, the validity and reliability of this system is verified through simulation under Modelsim circumstance combined with online logical analyzer. © (2014) Trans Tech Publications, Switzerland.
