Research on outburst prediction based on MATLAB's ANN;

3115 coal mining face in Qinchi Mine,the gas outburst prediction information of the air retuning gateway and the air income gateway and the related parameters from the tests of 5 coal samples,the assessment on the outburst danger of the coal mining face was made individually with the unit index,comprehensive index method and remnant gas content method.

Application of grey relevancy analysis method in index optimization of outburst forecast when a cross-cut is uncovered;

The fast measurment equipment was developed on the basis of above research,thus it can provide means'guarantee for popularizing the new synthesized index of outburst forecast.

The grey theory and neural network method were applied to coal and gas outburst forecast.

Research and application of sanding prediction model for high water-cut oil wells.;

Research progress of sanding prediction method of oil wells.;

Research on sand production prediction in screen out fracturing well;

Sand production prediction is important because of the safety, environmental, and operational concerns involved when produced sand particles fill and plug the well bore, erode down-hole and surface equipment, and increase operating expense.
