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Through the research on the rules of coal and gas outburst in mine outdated district,setting up regional prediction models between outdated district geology exploratory boring data and outburst index by quantification theory,then distribute the mine outdated district and check up the accuracy of the prediction models.

Mechanism and region prediction of coal and gas outburst;

Various prediction methods,indexes and techniques were applied to develop coal and gas outburst regional prediction information system,realizing the data visualization;the accuracy of region prediction is then increased.

Geo-dynamic division method based on the theory of plate tectonics is a new way to conduct region prediction of mine dynamic phenomena.

Based on sensitive factors usedfor regional prediction of coal and gas outhursts, the inference knowledge model of outburst prediction is set up inthe paper.

In allusion to the problems in prediction and estimation of manganese ore resources in western Guangxi-southeast Yunnan region, a field theory based dynamic buffer analysis algorithm, a distance field algorithm based on vector structure data, a basin bay extraction method based on mathematical morphology and a prediction model with combinations of domains are proposed.
