Gas Drainage Improvement in Underground Coal Mines
Effective gas management is vital to the success of the longwall mining in the Bulli seam, in the Southern Coalfield, Sydney Basin, NSW, Australia. The evolution of gas drainage methods and practices are discussed with respect to gas type, gas drainage lead time and prevailing geological conditions. Both underground to inseam drilling and surface to inseam drilling techniques are described at b...
متن کاملRock dusting considerations in underground coal mines
Rock dusting to prevent coal dust explosions has been in widespread use in U.S. underground coal mines since the early 1900s. Underground coal mining technology has changed significantly over this same time period, becoming highly mechanized and produces finer coal dust particles which are more explosive. Despite the advances in mining technology, mine-wide dust sampling practices have remained...
متن کاملPneumoconiosis in Central Indian coal-mines.
Extensive surveys carried out in Europe and America have shown the incidence of coalworkers' pneumoconiosis to be widespread (Flinn, Seifert, Brinton, Jones, and Franks, 1941; Fletcher, 1955). In India, however, the prevalence of this disease has never been investigated, and a report published by the government of India in 1946 (Deshpande, 1946) stated that there was no conclusive evidence that...
متن کاملThe Impact of Contract Operations on Safety in Underground Coal Mines.
OBJECTIVE The aim of this study was to test for differences in injury rates for contractor-operated underground coal mines relative to owner-operated mines in Kentucky, controlling for other covariates. METHODS We used disparities between MSHA contractor data and surface reclamation permit data to identify mines operated by contractors. We then used negative binomial regression to estimate in...
متن کاملNoise variability in underground room and pillar coal mines.
Noise in an underground coal mine has dominant components generated mainly from 3 sources: (a) continuous mining machines, (b) roof bolters, and (c) cars/vehicles used to transport personnel and/or coal. Each of these 3 noise sources also has a number of well-defined sub-sources with their own noise characteristics. Sound level meters were used to collect noise data in the form of instantaneous...
