Present Situation and Issues of Coal and Coal Preparation in India

Preparation and Transportation of Coal

Survey of noise in coal preparation plants.

In response to the continuing problem of noise induced hearing loss (NIHL) among mine workers, the National Institute for Occupational Safety and Health (NIOSH) has conducted numerous noise surveys in coal preparation plants. The research, consisting of worker dose monitoring, task observations, and equipment noise profiling, was completed in eight separate preparation plants. Worker dose monit...

Noise Reduction in New Open-cut Coal Mines, Coal Handling and Preparation Plants

Noise emission from coal handling and preparation plants continues to be an important issue in Australia, with increasingly stringent legislation and environmental constraints being imposed on plant construction and operation. In recent times plant designers have endeavoured to obtain practical data to assist in the design of plants with reduced noise levels. A plant designed and built recently...

A Novel Approach for Beneficiation and Dewatering of Coal Fines for Indian Coal Preparation Plant

An attempt has been made to beneficiate the Indian coking coal fines by a combination of Spiral, flotation and Oleo Flotation processes. Beneficiation studies were also carried out on 0.5mm coal fines using flotation and oleo flotation by splitting at size 0.063mm.Size fraction of 0.5mm-0.063mm and -0.063mm size were treated in flotation and Oleo flotation respectively. The washability studies ...

Occupational noise induced hearing loss in coal miners and coal washing factory workers in Kerman province

Introduction: The occupational noise induced hearing loss is one of the wide spread problems and a long term complication of working in noisy environments. At the present, large groups of workers who are working in noisy environments are exposed to hearing loss. So, this study is aimed to determine the prevalence of hearing loss (more than, 25 dB) of the workers in coal mines and leaching fac...
