Then the design and characteristic of the hydraulic support and critical parts are introduced,at the same time,presents the main technical parameters and corresponding matching equipment is presented.

It is suggested that the leader should take the initiative to grasp not only the overall design and the supplementary equipment construction, but the civil engineering technological design and the layout of metrology standard equipment.

This paper introdues EBH/J—132 driving mechinery and auxiliary equipment,and test result that applicated shortwall mining in 51 mining area of Wuyang coal mine of Lu′an many problems are analyzed,improvement schemes are raised.

In view of D\-N 1600 mm Multichamber drying tower, its drying mechanism , structure design, parameter calculation, operation effect, problems and some measures are discussed , also the choice of the matched equipment is made.

Current situation and development trend of mobile base station standard equipment maintenance;

Development and application of standard equipment for fully mechanized high cutting mining face in thick seam;

Checking calculation of jacking corollary equipment data accurately
