To address the challenges faced by coal miners when encountering collapsed pillars in local hard rock formations, we researched ultra-deep hole loosening blasting technology. overcome issues related to inapplicability of existing zoning theories and lack a solid foundation for borehole design sites, introduced model theoretical calculation formula based on thick-walled cylinder theory. Building this foundation, proposed coupled uncoupled charge methods that take into account strain rate...
Abstract To examine the disparity in deformation behavior and mechanical qualities between anchor cables with C-shaped tubes regular under shear conditions. The double-sided tests of free-section were conducted utilizing indoor large-scale double-shear test equipment varying pretension loads. indicate that inclusion tube alters stress distribution inside mitigates impact concentration. Moreover, it facilitates transition cable's failure mode from a mix tensile breaking to mainly breakage. In...
In roadways with high ground stress or burial depths, the joints distributed within rock formations are subject to complex stresses and interlayer misalignments frequently. Rock bolts cable anchored in tensile shear forces. Most of used roadway engineering local anchored, resulting insufficient strength at bolt free end close surface increasing breaking. The anchor C‐shaped tube (ACC) is a highly prestressed that can withstand force its end. This paper examines effect relationship between...
In order to deeply understand the influence of different factors on characteristic indicators double‐row‐pipe partial horizontal frozen body in sand‐gravel stratum under effect seepage flow, several sets model tests were carried out based similarity theory. The research showed that (1) backwater surface is shape a quadratic parabolic and development velocity inversely proportional square freezing time. downstream length front stronger than refrigerant temperature; (2) overlap time second row...
Abstract The stability of roadway is great significance to mine safety production. In this paper, according the geological conditions Xinyu coal mine, cross-section form track optimized. Under condition same ratio height width, rectangular section, circular arch section and straight wall semicircular are designed respectively. FLAC3D used establish numerical model simulate three kinds forms. optimal obtained by analyzing displacement field, plastic zone distribution stress field. results...
In this study, a new numerical scheme with variable-coefficient dispersive conditions was developed to simulate tsunamis over slowly varying topography. The model using novel time-space decoupled that used the classic wave equation. By adapting tsunamis, condition derived consider effects truncation error from scheme. stability and range of variable coefficient were analyzed analysis. Using specific modified scheme, uniform grid system can be tsunami Numerical experiments for propagation...
Abstract Aiming at the considerable deformation of surrounding rock and difficulty supporting a roadway affected by mining close-distance coal seams, this paper takes 10607 gas extraction Malan Coal Mine as subject study, an analysis stress distribution is conducted using circular hole problem involving plane strains. Using mechanical model roadway, formula for second invariant J 2 deviatoric theoretically derived. The characteristics pillar floor longwall panel are analyzed simulation...
Abstract In view of the serious deformation roadway 2220 in Majiliang Coal Mine after excavation, surrounding rock characteristics and stress redistribution are studied analyzed by numerical simulation technology, support optimization is carried out. The research results show that original scheme can not effectively reduce area plastic zone concentration excavation. After scheme, shape variables roof floor two sides obviously reduced, also greatly which significantly improves overall...
