A few points of suggestion for improving blasting effect in tunneling operation at small or medium scale underground mines;

The disappointing blasting effect is difficult to slove in mining project in Yichun Tantalum-niobium Mine.

In order to analyze the blasting effect of linear charge at different cavity ratios, the changes of stress field and the destroyed effect at five cavity ratios were investigated by dynamic photoelasticity in experimental models.

Study on forecasting smooth-surface blasting effects based on BP neural network;

Prediction of bench tight blasting effects by genetic neural network;

Based on the analysis and research on the cause of the higher total cost resulted from high blounder yield and frequent rock toes in a certain quarry,a series of technical measures,which takes improving blasting effects as center,are put out.

The design and the mechanics principles of directionally demolishing a tower building by blasting,the implementation method,the protection measures and blasting effectiveness are introduced.

lasting result is subject to multifactor in open pit mine This paper puts forward a new multifactorial comprehensive fuzzy method on blasting result evaluation Considering the characteristics of bench blasting in large opencast metal mine, two practical models for comprehensive evaluation, Four Factors Model and Ten Factors Model, are presented and several examples are given

This papr is introduced the demolition preparation, design, blasting process and blasting results.
