Abstract: According to the macroscopic and microscopic structural features and formation conditions of tectonic coal in Zhuxianzhuang mine, with reference to Ju Yiwen classification scheme, the tectonic coal may be divided into eight types:fragmented, porphyroclastic, granulated, mealy, flake, scaly, mylonitic and heterogeneous structure coal. At the same time, different tectonic coals were selected for mercury injection test, the characteristics of pore distribution, the characteristics of evolution of the pore aperture structure, the type and the conductivity of pores were analyzed. The results showed that many properties of tectonic coal are closely related with the deformation intensity. The sequence from the weak to the strong deformation of the tectonic coal in Zhuxianzhuang mine is as follows:flake, cataclastic, porphyroclastic, granulated, scaly, heterogeneous structural, mealy and mylonitic coal.
