Advances in Civil Engineering, Volume 2026, Issue 1, 2026.The accuracy of straightness monitoring of scraper conveyors seriously restricts the development of unmanned mining technology in underground coal mines. Fiber Bragg grating (FBG) sensors have the characteristics of passive intrinsic safety and have broad application prospects in coal mine underground monitoring technology.

Geofluids, Volume 2026, Issue 1, 2026.Floor heave control becomes more and more prominent in engineering practice with the increased mining depth of the working face. The gob‐side entry of the 21404 working face in Hulusu Coal Mine was taken to be the engineering background to study the gob‐side entry’s floor heave in the working face with a deep, thick, and dense layer of coal.

Prevention of gob ignitions and explosions in longwall mining using dynamic seals
International Journal of Mining Science and Technology, 2017 Most, if not all longwall gob areas accumulate explosive methane-air mixtures that pose a deadly hazard to miners. Numerous mine explosions have originated from explosive gas zones (EGZs) in the longwall gob.
