The Survey Books document the various mines that were owned and operated by the company for over 100 years. These notebooks were used by surveyors to record both surface and underground data collected while surveying, such as distances, bearings (directional readings), elevation readings, surface property lines, and descriptive information on the location of the survey measurements. These readings enabled the mine engineers to plot and map the progress of mining underground and to locate surface features relative to the underground mine.

In addition, some of the books document the innovations that CONSOL introduced, such as disco, coal slurry, and the use of a coal-to-gasoline plant. Many of the books show day-to-day business activities and include information on coal companies and railroads that did business with CONSOL and accidents that occurred in the mines.

The Survey Books are organized into nine smaller subseries. The books range in date from the late 1800s until the 1990s. The books are arranged alphabetically by mine name and then by book number, the numbering system being the original arrangement from CONSOL.



This subseries includes books labeled alphabetically by mine name. These books constitute the largest subseries in the collection of survey books. Other materials also include strip-mining operations and mines that were leased separate from CONSOL.



This subseries consists of notes and other loose papers that were interweaved between the pages of the transit books. They are organized alphabetically by mine name and are in individual folders. The material includes notes about changes to measurements, correspondence and blueprints of the mines.



This subseries includes information on the companies that did business or were associated with CONSOL. Companies include other coal companies, steel and iron companies, coke companies, and cleaning plants.



This subseries includes information on the railroads that did business with CONSOL, or that CONSOL had an interest share in stock. Railroads include the Pittsburgh and Lake Erie Railroad, the Pittsburgh-Taylortown Railroad, and the Baltimore and Ohio Railroad. Other materials in the subseries detail railroad extensions, measurements and proposed railroad locations.



This subseries includes detailed information on accidents that occurred within the mines. The books list the name of the person injured, how the person had worked in the mines, and descriptions of the events that occurred which led to the accident. Books identify any witnesses and compensation that went to the families of injured persons.



This subseries includes miscellaneous notes having to do with the company and the mines. Materials included are benchmarks that had been met, coal slurry pipelines, an index of the books, haulage amounts, time books and well and gas locations.



This subseries includes information on outside notes from the mines. Mine engineers would use these books to record a multitude of annotations, such as road levels, creek locations and land elevations. The books can include information on mines, railroads, and topography. The books are further organized by issuing Division.



This subseries includes books that focus on property surveys around or of the mines. Farmlands, estates and other land tracts are detailed and drawn out with levels and elevations.



The books in this subseries illustrate the topography of the mines and other land that was of interest to CONSOL.



Traverse logs were used by surveyors and mine engineers to calculate and convert the field survey data collected in the Survey Books to latitude (north-south) and departure (east-west). The calculated information was then in a form such that the data could be added to the surface and underground maps and drawings maintained by the mining company. These books are arranged in alphabetical order by mine name.



This series includes atlases, maps, technical drawings, information sheets, reports, etc. produced in conjunction with or to be used with the mine maps. It also includes some company records.

The Monongahela River Consolidated Coal and Coke Company was a railroad and coal transportation company, founded in 1899 in Pittsburgh, Pa. It was formed by merging more than 80 independent coal mines and river transportation businesses, both in Pennsylvania and Kentucky. Initially, it had an agreement with the Pittsburgh Coal Company to ship its coal only by water, and to not compete with it by using rail transport, but the agreement was ended in 1902. It merged with the Pittsburgh Coal Company on December 24, 1915. (From Wikipedia)



This series contains monographs, serials, articles, newsclippings, brochures, etc. about CONSOL Energy and other activities related to coal mining. It was processed during the summer of 2011 and added to the finding aid in October. Issues of CONSOL News and CONSOL Energy News were added to the collection in 2013.



Issues of CONSOL News and CONSOL Energy News are online in Historic Pittsburgh. Only copies of CONSOL News are in the collection; issues of CONSOL Energy News were borrowed from CONSOL Energy, Inc. for scanning purposes.



This series contains records and maps gathered together by CONSOL for use by officials investigating the 2002 Quecreek Mine accident. Nine miners working in Quecreek Mine No. 1, thinking they were a safe distance from mine voids, accidentally broke through to the abandoned Saxman Coal & Coke Company's Harrison No. 2 Mine at approximately 8:50 p.m. on July 24, 2002. This resulted in the flooding of the Quecreek Mine, trapping the miners for nearly 78 hours. The series also includes the final reports of investigation filed by the Commonwealth of Pennsylvania Department of Environmental Protection’s Bureau of Deep Mine Safety and the United States Department of Labor’s Mine Safety and Health Administration. The materials are further divided into 13 topical subseries and range in date from 1900 to 2004. This series was processed during the spring/summer of 2011 and added to the finding aid that October.

This subseries contains Field Survey Books for mines in Somerset County. These are notebooks used by surveyors to record both surface and underground data collected while surveying, such as distances, bearings (directional readings), elevation readings, surface property lines and descriptive information on the location of the survey measurements. These readings enabled the mine engineers to plot and map the progress of mining underground and to locate surface features relative to the underground mine.



This subseries contains Traverse Logs for mines and property in Somerset County. These were used by surveyors and mine engineers to calculate and convert the field survey data collected in the Field Survey Books to latitude (north-south) and departure (east-west). The calculated information was then in a form such that the data could be added to the surface and underground maps and drawings maintained by the mining company.



This subseries contains files relating to past mining activities in the Casselman River area gathered for use in a United States Environmental Protection Agency investigation into allegations of mine water discharges into the river. Original arrangement and folder names have been maintained.



This subseries contains maps of underground and strip mines in Somerset County. The maps are arranged by type of storage unit (Roll or Map Case) and then alphabetically by mine name.



This subseries contains maps of property in Somerset County. The maps are arranged by type of storage unit (Roll or Map Case) and then alphabetically by name of person or company associated with the property.



This subseries includes surface maps of townships, boroughs, counties, etc. Maps of an entire county (or a major portion of it) are filed first, followed by maps of individual boroughs and townships. Each group is arranged by type of storage unit (Roll or Map Case) and then alphabetically by location name.



This series includes all non-print materials in the collection, such as photographs, negatives, slides and aperture cards. These boxes are shelved in the Media Room. A portion of the images have been selected for digitization and are available online.

Prints depicting first aid demonstrations and competitions sponsored by the coal mining industry, and the mining rescue teams that participated in them. The history of such gatherings dates to October 30, 1911 when the first national mine-safety demonstration was held at Forbes field, in Pittsburgh. The demonstration was planned and managed by engineers of the Bureau with the aid of miners and coal operators of the Pittsburgh district. It embraced exhibits that demonstrated the character of nearly every branch of the Bureau's investigative work in relation to mine accidents, including first-aid and mine-rescue work, coal-dust explosions, and also special coal-dust explosions at the Bureau's experimental mine at Bruceton, Pa. Approximately 15,000 persons attended the demonstration. Thenceforth, first aid contests were annually held in mining towns across the Appalachians and mining country.



This series primarily includes maps, plans and technical drawings relating to mines and buildings owned and operated by the Union Coal and Coke Company in eastern Washington County, Pa. There are also some maps, plans and technical drawings relating to mines owned and operated by the Ellsworth Collieries Company and other coal operators near those of the Union Coal and Coke Company. Additionally, there are maps of towns and property associated with all of these mines. This series was added to the collection in March 2013.
