Coal Mining Concepts and Terminology

The video explores the formation and types of coal found in Pennsylvania, focusing on bituminous and anthracite coal. It explains the process from peat to lignite, then to bituminous and anthracite, highlighting the role of sedimentation, compaction, and heat. The video also discusses the structure of coal beds, mining decisions, and the quality of coal. It concludes with an invitation for viewer interaction.

What is an outcrop in the context of coal mining?

• A location where coal is exposed at the surface

• A mining tool

• A method of coal transportation

• A type of coal

What is the first stage in the formation of coal?

• Anthracite

• Lignite

• Peat

• Bituminous

Which type of coal is known for having a high moisture content and low carbon content?

• Coke

• Bituminous

• Anthracite

• Lignite

What is the primary use of coke derived from bituminous coal?

• Electricity generation

• Steel production

• Heating homes

• Gardening

What geological process contributes to the formation of anthracite from bituminous coal?

• Plate tectonics

• Erosion

• Weathering

• Sedimentation

What is a common characteristic of anthracite coal?

• High moisture content

• High carbon content

• Low carbon content

• High sulfur content

What are 'partings' in a coal bed?

• Layers of pure coal

• Gaps between mining shifts

• Tools used in mining

• Sedimentary layers between coal seams

Why might a mining operation choose to ignore certain small coal seams?

• They are too deep

• They contain too much moisture

• They are not economically viable to extract

• They are too close to the surface

What is a 'comb bank' in the context of coal mining?

• A type of coal seam

• A tool for breaking coal

• A pile of discarded slate and rock

• A method of coal transportation

What is the main challenge when mining coal with many partings?

• Too much carbon content

• High moisture content

• Difficulty in adhering to top rock

• Excessive sulfur content
