Based on comprehensiveness analysis and calculation on data from blasting experiments including blasting crater, incline bench, different distance of hole,initiation in multi-row and same stage, optimization of blasting parameters such as distance of hole bottom, minimum burden, explosive consumption an unit etc.

Predication and calculational software for slope displacement of unequal interval gray model;

According to the equal interval gray forecast GM(1,1) model,an unequal interval gray forecast GM(1,1)model was established.

The original grey GM(1,1) model is usually used in simulation and prediction of equidistant monitoring data sequentce,but the actual situation is the monitoring data which obtained appear unequal interval phenomenon because of some reason.

The substance of face milling cutter with unequal blade spacing is analyzed and the corresponding vibration reduction mechanism is discussed.

The straight line interpolation,the cubic spline interpolation,and BP neural networks are used respectively to change the unequal time interval data sequence into an equal time interval data sequence within MATLAB language generator,and the settlement is forecasted according to gray theory.
