The Transformation of Coal-Mining Waste Minerals in

The cement industry has the potential to become a major consumer of recycled waste materials that are transformed and recycled in various forms as aggregates and pozzolanic materials. These recycled waste materials would otherwise have been dumped in landfill sites, leaving hazardous elements to break down and contaminate the environment. There are several approaches for the reuse of these

This study evaluated CO and CO2 emissions from spontaneous heating of a U.S. coal sample in an isothermal oven under different airflow ventilation rates from 100 to 500 cm3/min. Experiments were conducted at oven temperatures of 70, 90, and 100 °C.

Pit Talk: the language of Britain’s coal Reaction

With the closure of the last coal mines and the ageing mining population, we must now collect such data with a greater sense of urgency as it will soon be lost to us forever. This language forms a large part of the identity and camaraderie of the miners and should be preserved for future generations to understand.

Coal mining World Coal Association

2 天前  Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining has finished.
