"Coal matrix shrinkage" refers to the phenomenon of contraction in the coal matrix, which is an important factor in the coal mining and utilization process. It has significant implications for coal seam methane extraction, coalbed methane production, and coalbed gasification. In the context of coalbed gasification, understanding coal matrix shrinkage is essential in predicting permeability evolution and gas production. In coal mining and utilization, the control and management of coal matrix shrinkage are crucial for ensuring safe and efficient operations. This collection of English short sentences and example sentences provides a comprehensive resource for understanding and discussing the concept of coal matrix shrinkage in the coal industry.
