AN IMPROVED ROCK MASS BEHAVIOR NUMERICAL MODEL AND ITS APPLICATIONS TO LONGWALL COAL MINING
TITLE: AN IMPROVED ROCK MASS BEHAVIOR NUMERICAL MODEL AND ITS APPLICATIONS TO LONGWALL COAL MINING The rock mass constitutive models should include elastic moduli, strength and stiffness of intact rock as well as those of joints and geometric properties of joints. The post-failure behavior of …

Development of a Method for Measuring Rock Mass Air Permeability and Applications to Underground Mining
… to many Saskatchewan mining operations. Rock mass behavior and stability have been linked to the presence of groundwater and the inflow potential. An estimate of rock mass hydraulic properties is an important factor for assessing groundwater inflow potential and the effect this may have on the …

Body dynamics and muscle activity during Chi running
This study compared the center of mass behavior and muscle activation patterns during Chi running and normal running. The study included 10 participants, both male and female, who were recreational runners training at least 5 days a week. Thirty-second trials were collected continuously on a …

Optimizing Pillar Design for Improved Stability and Enhanced Production in Underground Stone Mines
… require continuous assessment of rock mass behavior for maximizing safety. Optimizing pillar design is essential for preventing hazardous incidents and improving production in room-and-pillar mines. Maintaining regional and global stability is complicated for underground carbonate or …

Politics and the American clergy: Sincere shepherds or strategic saints?
… the causes of clergy political preferences and behavior for decades. As with party ID in the study of mass behavior, personal ideological preferences have been the relevant clergy literature's dominant behavioral predictor. Yet to the extent that clergy operate in bounded and specialized …

Stereological Interpretation of Rock Fracture Traces on Borehole Walls and Other Cylindrical Surfaces
… permeability, and other mechanical and hydraulic behavior of rock masses. The characterization of fracture systems is of great significance for understanding and analyzing the impact of fractures to rock mass behavior. Fracture trace data have long been used by engineers and geologists to …

Monitoring Underground Mine Displacement Using Photogrammetry and Laser Scanning
… with the potential to monitor movements of rock masses and their support systems in underground mine environments. Displacements underground are traditionally measured through point measurement devices, such as extensometers. These are generally restricted to measuring one dimension, may change …

Seismic Wave Velocity Variations in Deep Hard Rock Underground Mines by Passive Seismic Tomography
… the safety of the mining workplace because the behavior of the rock mass associated with mining-induced seismicity is poorly-understood. Passive seismic tomography is a tool with which the performance of a rock mass can be monitored in a timely manner. Using the tool of passive seismic …

Developing Prefabricated, Light-weight CLT Exterior Wall Panels for Mid-rise Buildings
… of a comparative parametric study on the thermal mass behavior of CLT and CMU wall systems via finite difference algorithm. One significant outcome of the simulation data analysis was the heat transfer dynamics within the CLT and CMU wall system when exterior insulation is applied. The analysis …

Wedge failure analysis of anchored rock slopes subjected to surcharge and seismic loads
… a problem of great concern. Because the rock mass behavior is significantly governed by the presence of joints or other discontinuities, several types of slope failure, such as plane failure, wedge failure, toppling failure, buckling failure and circular failure, are often observed. The …

Süreksizliklerin statik ve dinamik koşullardaki kesme dayanımının yapay süreksizlikler yoluyla karşılaştırılması
… gerektiği sonucu ortaya çıkmıştır. Rock mass behavior is very different from that of intact rock. Estimation of the strength of rock masses under monotonic loads is relatively easy; however, the same cannot be said for the dynamic loading conditions because the estimation is more …
