Rock Mass Blastability Classification with Fuzzy Diagnosis;

Analysis of Influence Factors of Rock Mass Blastability by Using Grey Theory;

Study on the Drillability and Blastability of the Ore / Rock of the No.2 Orebody in Tongkeng Mine;

Use of the effect measure analysis can conduct relative rating of rock blastability while at thesame time complete the systematical analysis of it,which is an information analysis method featured with simpleand fast calculation,flexible application and high adapability.

A mathematical model using the fuzzy hierarchy analysis for rock blastability appraisal is presented;the basical principle and the calculation of this method are described;and is applications are illustrated by fieldcases.

The detonation reliability of different model of nonel tube immersed in heat conducting oil and diesel oil have been studied in this paper.

This article tested a series of Nonel tube in appearance,detonation reliability,tensile intensity,etc,which has been stored for no less than 24 years.

This paper presents an attempt to evaluate the explosible gas distribution by solving the concentration equation based on the previously simulated wind flow field.
