This article takes the low permeability coal seam in the coalfield of South Judger Basin in Xinjiang, as a research object.The pore structure characteristics of coal rock mass in low permeability coal seam were analyzed quantitatively using scanning electron microscopy (SEM) through the methods of statistics and digital image analysis.Based on the
Abstract Here, we present a remarkable methodology for unveiling subsurface structures with the potential to transform the exploration of mineral and ores resources, as well as the study of volcanic activity.By incorporating the Metaheuristic Bat algorithm (MBA) with the second horizontal gravity gradient st albans alpaca scarf (SHG) and employing
Introduction Early 1800 tequila lafc relationship experiences with parents or other important caregivers provide the matrix on which people form subsequent bonds in their lives.An attachment style relates to how people perceive themselves and significant others in terms of the possibility of obtaining support and care in stressful situations.There
These days, composite materials successfully substitute the traditional materials due to its various significant applications.This paper examines the influence of fiber orientation and fiber length on electrical properties of PALF reinforced Bisphenol-A composite and explores the potential of using PALF as reinforcing material for electrical applic
In the interaction of the rolling stock and the upper structure of the railway track, intense dynamic loads occur.They have a destructive effect both on the parts of the rolling stock and on the elements of the superstructure of the track.In order to develop a durable, rational and reliably functioning design of cars and locomotives with good dynam
