摘要

Disclosed is a method for designing supporting parameters of a transition support for a mixed mining face of filling and fully-mechanized mining. The method includes: first, determining a total length of a mixed mining working face and a length of a filling section according to requirements of a coal mining production capacity of the mixed mining working face and a filling capacity of the filling section working face; then, establishing a mixed mining numerical model of filling and fully-mechanized mining by using three-dimensional distinct element software, and simulating and calculating a caving height of a roof of a transition section and a stress influence range of the transition section when a filling rate of a mined-out area of the filling section changes; based on a result of numerical simulation and calculation, performing curve fitting according to a correlation coefficient to obtain a functional relationship between the filling rate and the caving height and a functional relationship between the filling rate and the stress influence range of the transition section; and finally designing supporting parameters of a transition support in combination with actual engineering geological parameters. The method can provide a reference for supporting design of a support, and enables a smooth transition between a filling support and a fully-mechanized mining support for a mixed working face, thereby further enriching filling mining theories and expanding the application range of filling mining.
