The mountaintops are removed to expose the coal beneath and the coal is extracted. Underground Mining Methods. If the coal seams are too deep underground, then deep underground mining is necessary. Deep underground mining methods include Continuous, Longwall, Blast, Retreat Mining and Shortwall Mining.

A new mining method 04 Introduction The mining methods used in open cut coal strip mining in most major coal producing countries have been well established and fairly consistent over the past few decades. These general mining practices have been described by Kukla et al. (1993) and Aspinall et al. (1993) amongst others.

MINING METHODS The phenomenal rise in coal production, nearly sixfold in the past three decades, necessitated rapid but judicious mechanization of mining methods. While opencast operations are now fully mechanized employing large capacity earth moving equipment, introduction of machinery in underground workings has been gradual.

Mining Techniques Equipment. Over the past 250 hundred years, the coal mining industry has witnessed significant changes to both its mining techniques and the equipment used throughout the mining process. Changes evolved through a need to make a safer underground environment for the thousands of miners employed in Cape Breton's coal industry.

According to the Organic Act, the USBM was, among other things, "to make diligent investigation of the methods of mining, especially in relation to the safety of miners, the use of explosives, the prevention of accidents." This reflects the origin of what eventually became known as the Pittsburgh Research Center.
