In this paper, the stress distribution characteristics of surrounding rock roadway are analyzed and the bimodal stress distribution model of gob-side entry roadway is proposed. On this basis, the calculation model of supporting load for the gob-side entry under the condition of stable floor is established and the corresponding calculation formula is deduced, which provides a theoretical basis for the quantitative design of gob-side entry support.
