waste waste rock in coal mining

PDF Sustainable use of mine waste and tailings with suitable

coal or ore extracted based on stripping ratio. Almost every coal as well as metal mining produces waste rock. The quantity of waste produced (shale and sandstone) in coal mines is in-terms of millions of cu.m per year. Sandstone is a highly porous rock and the strength is medium, so it may not be suitable for pavements.

Understanding Mining Waste Management and Disposal Methods

Improper mining waste disposal will lead to air, soil, and water pollution. Different types of mining include landfill mining, coal mining, oil and gas extraction, metal, and non-metal ore mining. In this article, we will look at different types of mining waste and how to manage it effectively. Types of Mine Waste 1. Rock or Solid Mine Waste

The reuse and recycling of coal mining waste with zero

Coal mining industries generate hundreds of millions of tonnes of waste coal, rock and cleaning waste stream containing fine coal (a by-product of previous coal processing operations), coal gangue, coal sludge, fly-ash, coal mine drainage and coal bed methane (CBM) that contaminate the landscape in the mining areas.

The Potential Use of Waste Rock from Coal Mining for the

Abstract. Along with the development of the coal mining industry, a massive amount of waste rock has been exhausted. It does waste not only plenty of natural resources but also pollutes the environment, as well as occupying a large part of the land use for dumpsites.

Tailings - Wikipedia

Coal refuse (also described as coal waste, coal tailings, waste material, culm, boney, or gob) is the material left over from coal mining, usually as tailings piles or spoil tips. For every tonne of hard coal generated by mining, 400 kilograms of waste material remains, which includes some lost coal that is partially economically recoverable.

How Is Mining Waste Recycled? - Ecocycle Australia

How We Recycle The Big Stuff. Rock and soil need to be moved to gain access to the coal, metal ores or other materials of interest. In some situations, it may be possible to sell rock and soil for a range of purposes as it is usually set aside for rehabilitation of the mine site after mining ceases.
