Safety Engineering College, Heilongjiang Science and Technology Institute, Harbin 150027, P.R. China;Based on bolt combined effect in the roof of mining roadway, the necessity conditions of load, span and deflection are proposed for stratification separation in the immediate roof. With strata combination of composite beams as key combination and Principle of Deformation coordination, the calculation formulas of the four key Support Technology parameters are obtained for length, spacing, distance between two rows and pretension force in bolt support of the roof of mining roadway.
