Fire is of major concern to those who work in underground coal mines. It is important to have a warning system that is capable of detecting fire and generating an alarm. In this paper, we present the design of an early warning system in a “Bord & Pillar” coal mine. It uses Wireless Sensor Networks (WSN) to detect the exact fire location(More)
Multilevel extended digital image correlation (X-DIC) technique based on finite element method (FEM) is applied for measuring deformation of geomaterials under uni-axial loading condition. The concept of Smooth Particle Hydrodynamics (SPH) is introduced for smoothing computed displacements as well as for calculating strain tensors at every nodal point of(More)
