Intensity analysis of frictional heat source during core tube sampling and drilling

Abstract Currently, the heat generated during coal core tube sampling causes rapid gas desorption, leading to substantial measurement errors in laboratory gas content assessments. Reducing these errors requires studying frictional heat from core tube friction against the hole wall and coal core temp...
