How Is Coal Processed And Transported

  • 1. Introduction

    Coal is a dual-porosity medium composed of matrix pores and fractures. Nanopores in the coal matrix are the source of coalbed methane, and the fracture between the matrices provides a channel for gas migration. Figure 7 (a) shows the microstructures of the coal reproduced from the literature (reproduced from Figure 1 in [31]). It can be ...
