Studying aerodynamic resistance of a stope involving CAD packages modeling

Abstract: In the article, aerodynamic resistance of the stope face is studied in case of selective mining the coal seam. To carry out the research, the methodology of the computational experiment for evaluating the longwall face aerodynamic resistance influence on the efficiency of airing the stope face has been substantiated. The model of the stope face section, equipped with mining and backfilling mechanized complex based on the serial 1KD90 roof support has been developed in the 3D modeling software SolidWorks.

“…More intense fracturing [37] and the occurrence of the so-called thrust-block systems in the roof increases their deformation capacity for more significant displacements, and rocks caved into the mined-out space radically change their mechanical characteristics [38][39][40]. These factors have been sufficiently tested using modern methodologies for modeling geomechanical processes [41,42].…”

“…Это указывает на изменение характера взаимодействия механизированной крепи и породного массива. Передняя и задняя часть стойки механизированной крепи находятся под воздействием знакопеременной нагрузки, что повышает вероятность посадки на «жесткое» [10][11][12]. Здесь и далее под определением знакопеременной нагрузки будем понимать состояние, при котором в выделенном объеме расчетной модели одномоментно формируются поле напряжений характеризующие сжатие и растяжение материала.…”
