This paper introduced the construction organization of pumping technique with high fall and long distance in transfer room.

According to the actual conditions of skip loading chamber of main shaft in Wangfenggang,such as big cross section,deep plane,big earth pressure and complicated geological conditions,scientific and feasible construction schemes were made to actualize the speed excavation and masonry construction of the super sized skip loading chamber.

This paper associates with specific construction condition, analyses the construction scheme for main shaft pan loading chamber, and chooses proper construction scheme.

In this article, the writers explain the constructing technology of unloading gallery, coalbunker and loading gallery that make up a transfer building In The Eighth Coal District of Qianying Coal Mine of Kailuan Group Company.

The skip loading chamber in the air shaft deepening project was designed very complicated,very difficulty to construction;and takes time up longer.

The plan and technology of skip loading chamber construction in Jining No.

This paper puts forward the reasonable optional method of timbering parameter for big section room construction,as well as the items should be noticed and the problems should be solved first in construction course.

Through analysis to weak coalbed and harmfulness to roadway,main haulage roadway and room supporting design and adaptability condition are discussed in weak coalbed.

According to service rife of room and feature of surrounding rock,pressure situation of room was analyzed,supporting parameter was counted on the basis of combined arch theroy.
