Abstract: In order to effectively solve the problem of the temporary support of the bolt supporting roadway in the non-mechanized
driving of 1501 machine roadway of Sangou Xindu Coal Industry Co., Ltd., on the basis of in-depth analysis of the advantages and
disadvantages, practicability and reliability of the existing temporary support methods of the bolt supporting roadway, such as the
point column, the front probe beam of the lifting ring, etc., the design of using the steel ladder as the bearing U-shaped slot,
equipped with movable U-shaped cards and the front probe beam of the square steel temporary support was proposed. Through
field practice and improvement, the design scheme of temporary support for double U-shaped concrete iron equipped with square
steel front probe beam is ideal, has significant practicality and reliability, which can effectively solve the problem of unsupported
roof operation in 1501 machine roadway.

Key words: bolt support; ring front probe beam; temporary support; double U-shaped concrete iron equipped with square steel
