The abrasion mechanism of mine fan blades is discussed from the aspects of the striking of solid particles and gas-solid flow,and the advantages and disadvantages of various abrasion theories are analyzed as well.

A system for Fan mine based on ST-JK06 intelligent monitor Terminal is introduced in this paper.

Design on reasoning engine of mine fan fault diagnosis expert system;

On-line monitoring system for mine fans

The article analyses the noise of source of ventilator in mine, giving the procedure of design of secondary muffler of ventilator in mine and using of comlex control technology, Effect of reducing noise is clear, the remarkable effect provides experience in dealing with the noise problem of ventilator of mine.

This paper gives the procedure of design of secondary muffler of ventilator in mine using newly signal processing,dynamic optimization, finite element method, analysis of sensitivity and stuctural amendment.

Based on the 3D parts and assembly models established in Pro/E for a new wind well excavator,a rigid model plus some constrains and marks is formed through interface of Mech/Pro,and then the model is transformed into ADAMS to further add some complex constrains and forces.
