Influence of peak-load operation of units on safety and economical efficiency of boiler equipments;

Type selection analysis for the boiler equipments of 1000 MW ultra-supercritical unit;

Dimensions of roadway and open-off cut were confirmed with reasonable equipment coordination of coal cutter,scraper and hydraulic supports in full-mechanized caving mining face.

This paper summarizes the different modes and methods of equipment coordination in inclined shaft construction, and proposes some views on the working line and the way of rapid construction of inclined shafts.

This paper introduced the development process and application condition of the inclined shaft construction technology, emphatically described the characteristics and techniques of equipment coordination, and the methods of drilling, blasting, and shaft water control.

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.

The article mainly introduces the key technology in machinery matching for the construction of bituminous concrete pavement of highways and the results of application in the pavement construction of Contract No.
