Coal is still the major resource to meet expanding energy demand and widely used in coal-fired thermal power plants taking advantage of rich reserves cost-effective production. Longwall mining a method that Türkiye, line with trend world, enables economical sustainable production underground coal resources mechanized equipment. Estimation stress distribution concentration zones excavation face ...

In this paper, I will show and describe a method of integrating infrared images with 3D model the front an excavation in longwall type workings. also test created for its potential usefulness geological prospecting, used looking changes layout at excavation. Geological information on amount coal is important economic side The mine does not want to take out waste rock, but mostly safety operatio...

The purpose of the paper is to substantiate width barrier and yield pillars for application a new seam development scheme in conditions Alardinskaya mine (Russia). develops gas-bearing coal seams that are prone spontaneous combustion hazardous due rock bumps, which leads frequent accidents. analysis world experience mining being bumps showed safe with longwalls can be provided by system inter-p...
