Abstract: The 16015 working face track tunnel in a mine is taken as the background to discuss the roadside control mechanism in thick coal seam under hard roof, and the "constant resistance yielding-supporting" roadside support method is proposed. The method is the roadside support combined constant resistance body with high strength uncompressed body, which allows the roof artificially controlled deformation and achieves the control of "given deformation" and "limit deformation" of roadway roof effectively under the condition that filling body can not be damaged. According to the characteristics of the roadway roof, the pressure height of the constant resistance body is 0.4 m, and the constant support resistance is 15 MPa. Using the numerical simulation method, the width of the filling body is 1.8 m, and the compressive strength is 25 MPa. Field tests show that the "constant resistance yielding-supporting" roadside support method can ensure good effects on gob-side entry retaining; the roadway can meet the needs of production safety.
