Coal in Indiana was discovered along the banks of the Wabash River in 1736. Organized development of Indiana's coal resources began in the 1830s and by 1918, production exceeded 30 million short tons. Coal production declined following World War I, but underground (deep) mining remained the primary mining method in Indiana until the 1940s.

The Coal Section stratigraphic database from which this .PDF file is derived is a multi-project database which contains drill hole and outcrop descriptions of Pennsylvanian stratigraphy in Illinois. Consequently, the level of detail and accuracy in the data and their interpretation vary (sometimes widely) with the geologist, project type, or ...

INTRODUCTION: The most important mineral resource in Sullivan County has been coal, and for many years the county was one of the most important coal-producing areas in Indiana. The value of the total product of the mines in Sullivan County has reached billions of dollars (at current prices), and mining is still being done. Mining has affected the lives of all citizens of the county, whether or ...

THIS book is the first of series of works on economic geology under the general editorship of Dr. J. E. Marr, F.R.S. The author is a recognised authority on the coal-bearing rocks of this country ...

Reserves of surface-minable coal in Indiana are a great store of wealth whose exploitation since 1915 has transformed the physical and economic landscape of Indiana's southwestern counties. In studying the coal resources of Indiana, the Indiana Geological Survey has compiled much engineering, economic, historical, and geologic information on the surface-mining industry.

The data is used to support a wide range of applications in such areas as global change research, agriculture, forestry, geology, resource management, geography, mapping, hydrology, and oceanography.

Underground mining is the oldest method of mining coal. From the late 1970s to early 1980s open pit operations increased, achieving high quantities of production and lower production costs. However, today, with environmental considerations and the greater depth of coal seam deposits, underground mining is proving to be the more viable alternative.

Abandoned Coal Mines in Utah. The Utah Geological Survey (UGS) has created this digital database of abandoned coal mine maps as part of its mission to provide information about Utah's geologic environment, resources, and hazards to promote safe, beneficial, and wise use of land. With funding from the Mine Safety and Health Administration, and ...

complementary data on the quality and mining possibilities of the coal. Keports on the geology and coal resources of the Coos Bay quad­ rangle by Diller (1899, 1901) and Diller and Pishel (1911) supplied the first comprehensive data on the coal resources of the area. More recent reports by the Oregon State Department of Geology and

Coal extraction has a long and complex history in Colorado. The estimated value of Colorado coal production in 2017 was $623 million. Although coal production slightly increased in 2017, the overall decreasing trend in coal production is due primarily to the nationwide increased use of natural gas and renewable energy. The state fell from the […]

This paper covers geologic exploratory methods, data organization, and the value of collecting and interpreting geologic information in coal mines to enhance safety and production. The implementation of the methods described above has been proven effective in predicting and mitigating adverse geologic conditions in underground coal mining.

Coal balls (brown masses) in an underground coal mine in the Amburgy coal bed, eastern Kentucky, and details of samples showing permineralized woody tissue (brown) in coal (black). Planning and mitigation: When mining the Springfield and Herrin coals, miners can be made aware of what coal balls are and what they look like.

A. THE ORIGIN OF COAL. The geological history of the Earth is divided into several epochs. One of these is called the Carboniferous. The Carboniferous is an epoch in the Geological record, which lasted from 359,2 ± 2,5 tot 299,0 ± 0,8 millon years ago. The Carboniferous is part of the Paleozoïc.

Find coal production data for Kentucky since 1790, which can be searched for by year and/or region or county. Data can also be viewed in a graph format or downloaded. Search the coal analyses database for coal quality data by county, quadrangle, or coordinates, plus stratigraphic parameters.

Description: This dataset contains two feature classes and three related tables representing the locations of historical coal mines in Washington along with links to digital copies of maps of these mines.

Coal has been one of most valuable natural resources since the 1300s when the Hopi Indians used it for the first time. European settlers began to use coal in the late 1740s and as immigration to the US grew and energy demand increased, coal production quickly climbed from 9.3 million tons in …

Symbols indicating mining-related features digitized from historical USGS topographic maps in the conterminous US. Includes prospect pits, mine shafts and adits, quarries, open-pit mines, tailings piles and ponds, gravel and borrow pits, and other features. Work is progressing from west to east.

Data collection points and observations should be dated, categorized, and digitized as soon as conveniently possible. Many times a single geologist is in charge of multiple mines, and it becomes difficult to keep data from one mine separate from the others.
