Study on correlation between pore development and strength characteristics of tar-rich coal in different coal seams

Study on correlation between pore development and strength characteristics of tar-rich coal in different coal seams

In the process of coal mining, the coal body is subjected to external force, resulting in pore penetration and strength decline, which is easy to cause engineering disasters such as roadway surrounding rock instability and roof collapse. In order to study the correlation and influence mechanism bet...
