In order to avoid the decline in big dip angle working face,this paper introduces some methods,such as,the feed from the top;one-way mining from the down;mining without knife from the top;the installation of anti-skid jack and sub-sequence moving,which achieve good results.

By using a simplified mathmatical mo del of landing gear,the computer sim ulation of operating process of the anti-skid brake system of an aircraft in landing is carried out.

Introduced in this paper is the technique to improve anti-skidding of the pavement micro and macro structures, in connection with the result from pavement anti-skid research in National Project 025.

Stones and tiles slip resistance testing standards/ PAN Shi-hong;

Testing results showed that the coat was excellent in abrasion resistance, stain resistance and slip resistance.

To Make an Approach to Antislip Reliability under the Condition of Emergency Braking;

Discussing the artificial hacking technology of cement antiskid pavement;

To prevent serious skidding and obtain maximum friction coefficient, a design of intelligent aircraft antiskid brake system is presented.

Aircraft antiskid braking system is complicated and nonlinear and it is so difficult to establish its exact model.

The construction technology of drainage,anti-skidding, noise-reducing,multi-function asphalt pavement is introduced based on the trail project in Wuhan to Yingshan expressway.
