Research on regional economic resilience has predominantly focused on urban contexts in Europe. This study extends the empirical foundation by examining rural agritourism resilience during the COVID‐19 pandemic in rural Chiang Mai, Thailand. Employing an evolutionary economic geography framework, this research traces the historical development of the ...

Considerations for Discrete Element Modeling of Rock Cutting [PDF]
This study attempts to build a framework within the Discrete Element Method (DEM) to produce a reliable predictive tool in rock cutting applications, such that the cutting forces and fragmentation process are reasonably estimated. The study is limited to

To study the influence of roof cutting and pressure relief on the surrounding rock control effect of gob-side entry retaining, numerical simulation was carried out by UDEC software, and the stress and deformation characteristics law of roadway surrounding rock under two states of whether the lateral roof collapsed or not were analyzed. The results show

Pressure-relief joint sample map.
To address the problem of large deformations in weak surrounding rock tunnels under high ground stress, which cause damage to initial support structures, this study proposes a novel type of circumferential pressure-relief joint based on the concept of ...
