Thermal environment prediction has become increasingly significant in recent years with its promise of wide application underground structures. The current work presents a numerical method for the feasible and effective analysis airflow surrounding rock temperatures ultralong mine ventilation roadways to understand their dynamic heat transfer. To reduce modeling effort computation time satisfactory accuracy, roadway is approximated as one-dimensional (1D) line element. Still, remains...
As the underground engineering proceeds to a greater depth, thermal stresses resulted from high-temperature surrounding rock become major challenge for deep construction and safe operation. Understanding of characteristics heat moisture transfer in roadway is critically required assist predicting improving environment underground. The present work developed fully coupled model capable simulating non-isothermal flow inside together with driven by water evaporation. And proposed has been...
Blockchain as a new technique has attracted attentions from industry and academics for sharing data across organizations. Many blockchain-based applications, such Internet of Things devices management, need privacy-preserving access services over encrypted with dual capabilities. On one hand, they to keep the sensitive private that others cannot trace infer stored in block. other support fine-grained control both time users’ attributes. However, best our knowledge, no blockchain systems can...
Heat hazard is major challenge for the safe and efficient exploitation of deep resources. Understanding heat transfer behaviors in roadway premise temperature prediction ventilation design. A fully coupled model incorporated with a moving mesh method was developed, which considers convective between surrounding rock airflow, unsteady-state rock, non-isothermal flow roadway. The characteristics thermal performance its evolution law an excavating were obtained. numerical validated against...
Reinforced Concrete (RC) beams in the building structures are usually assumed as a ‘T’-shaped beam when effects of adjacent slab flange considered. However, experimental studies on residual flexural behavior RC rarely reported. The two rectangular and one after exposure to ISO834 standard fire were experimentally investigated paper. detailed results, including measured temperatures, capacity, load-deflection curves concrete strain presented. temperature distribution analyzed. results show...
The problem of heat hazard in tunnel engineering has seriously affected the normal work personnel and machinery. After combining control method controlling energy source blocking transfer, a technical scheme precise thermal insulation at working face concert with geothermal extraction is proposed, forming coupled cooling ventilation partial insulation. By building scaled model test platform, temperature field area was analyzed, effect factors, such as or without layer, velocity, surrounding...
A steady and proper thermal environment in deep underground is imperative to ensure worker health production safety.
