Coal Refuse Disposal Using Engineering Design and Lime Chemistry

Leachate Chemistry of Mixtures of Fly Ash and Alkaline Coal Refuse

In the past, acid mine drainage (AMD) associated with coal mining operations and the disposal of coal refuse have been a driving force behind research efforts on the properties of coal combustion products (CCPs) [1]. The results from research over the last 15 years clearly indicate that bulk-blended CCP has the potential to ameliorate AMD production in coal refuse as long as acid-base balance c...

Determination and assessment of coal bed methane potential using rock engineering systems

The presence of methane in coal mines is one of the major problems in underground coal mines. Every year, in underground coal mines, a lot of casualties due to outbursts and explosions of methane gas is occurring. Existence of this gas in the mines not only creates a difficult and dangerous situation for work but also makes it more expensive. The release of this gas to the air causes a further ...

Chemistry of rubber processing and disposal.

The major chemical changes during the processing of rubber occur with the breakdown in mastication and during vulcanization of the molded tire. There is little chemical change during the compounding, calendering, extrusion, and molding steps. Reclaiming is the process of converting scrap rubber into an unsaturated, processible product that can be vulcanized with sulfur. Pyrolysis of scrap rubbe...
