Abstract: Aiming at the traditional “double-lane layout” method which is prone to induce dynamic disasters such as rockburst in deep mines, this paper summarizes and analyzes the advantages and disadvantages of the existing roadway layout methods of rockburst coal face, and establishes the concept and layout of double-connecting roadway. At the end of the thesis, the technical idea of applying the of double-connecting roadway to the coal mining face of the rockburst mine is proposed. By establishing the mechanical structure model of the roof of the double-connecting roadway before and after mining, the relationship between the stability of the double-connecting roadway and its span and the relationship between the resistance of the partition wall support and its width are obtained. The application of double-connecting roadway not only solves the problem of “double-lane layout” but also realizes the function of “double-lane layout” which can provide a reference for the design of coal mining working face in rockburst mines.
