Engineering disasters occur frequently and violently with the increase in mining depth, which is mostly due to insufficient study on failure mechanism of deep rock mass. In this paper, theoretical experimental researches behaviors deformation control surrounding recent years were reviewed. Macro/meso or coal–rock combined body under different loading conditions have been systematically investigated. Stress gradient theory rock, uniform strength support roadway, analogous hyperbola movement...
Hoek–Brown failure criterion is one of the widely used rock strength criteria in mechanics and mining engineering. Based on theoretical expression parameter m an intact rock, has been modified by crack parameters for fractured rocks. In this paper, value range form were discussed. A critical B was defined to describe influence when stress at peak, while a b introduced represent distribution average initial fractures. The contained influences (B), confining pressure (σ3) fractures (b). Then...
The phenomena of strong pressure occurrences have been observed many times in the #311103 working face Bayangaole Coal Mine. Deep‐hole blasting measures were used to relieve order decrease danger levels these on face. layouts proposed this study differed from conventional a “straight‐line” design by instead utilizing “triangular‐fractal” and “deep‐shallow‐fractal” for purpose successfully driving explosive efficiency enlarging roof‐blasting range. fractal dimension layout was calculated as...
Rock burst is one of the major dynamic disasters that directly threaten production safety in coal mines. According to current research, occurrence rock can be described by generalized Newton’s second law with three elements which are research object, force condition, and motion state. These refer mass mining area, concentrated static loads, instability surrounding rock, respectively. On this basis, a comprehensive method involving was proposed, especially focuses on investigation into...
