# 基于火柴棍模型的煤体迂曲度理论研究Theoretical Research on Tortuosity of Coal Based on the Matchstick Model

Abstract: In order to research the structure characteristics of pores and fissures and seek the related cha-racterization parameter of coal, this article based on the ideal matchstick model, combined the Darcy equation and the modified Poiseuille equation and deduced the theoretical expression of tortuosity applicable to coal through strict theoretical derivation. Then the modified expression of tortuosity was deduced in reference of the initial tortuosity, at the same time, we got a calculation method of initial tortuosity by combing the Klinkenberg coefficient. The research results provide a feasible method for calculating the related parameters representing the features of pores and fissures, and have positive effect.
