In order to get less encoding time and lower average encoding bit rates, a fast encoding algorithm, which integrates advance correlation predictive process with a fast search encoding algorithm, h.

In this paper, an incidence prediction hierarchical algorithm of integrated system optimization and parameter estimation for nonlinear discrete dynamic large\|scale system is introduced.

Study on the regional prediction of miningdynamic phenomenon;

Visualization research on regional prediction of coal and gas outburst based on GIS;

Through the research on the rules of coal and gas outburst in mine outdated district,setting up regional prediction models between outdated district geology exploratory boring data and outburst index by quantification theory,then distribute the mine outdated district and check up the accuracy of the prediction models.

The paper analysed geological characteristics of Hongshan igneous rock mass and its extended range in the western Hongshan predicting area and studied the influencing extent to coal seams in the Beizhang exploration area and neighbouring Jiaoyao coalmine.
