Coal Status Report Form

Coal Status Report Form

1. When there are two or more coal seams which have been researched for the site in question, then the information for each seam is reported on a different page of the report. For example, if you have a three page report, then there were three coal seams researched for that site.

2.The name and address of the person requesting the report is placed in the upper left field of the report.

Return to Form

3. The address of the site that is being researched is placed in the upper right field of the report. If an exact address is not known, then a general location is given.

Return to Form

4. The municipality and county where the site being researched is located is identified.

5. Most coal status reports are requested by people who want to know if their property has been undermined so they can determine if they should have mine subsidence insurance. In those cases ""MSI" will be indicated as the purpose of the report. People also request information on mining for various other reasons not related to the insurance program. In cases where there is mining indicated on the report and "MSI" is indicated as the purpose for the report, information on the insurance program is sent out along with the mining information unless a request for insurance has already been received.

6. When researching mining, the site is first located on an USGS topographic quadrangle map. These are rectangular maps that are based on 7.5 minutes of longitude and latitude and are named for a population center which is located on the map. The location of the site being researched is measured from the the southeast corner of the map and recorded on the Coal Status Report. If additional information is requested for the site, these measurements are used to relocate the site. All underground mine maps in the office are indexed according to the USGS map(s) they are associated with.

7. Each page of the report contains information about a different coal seam. The coal seam that was researched is listed here. Some coal seams commonly found in southwest PA include: Pittsburgh, Upper Freeport, Lower Freeport, Upper Kittanning, Middle Kittanning, Lower Kittanning, and Brookville.

8. The name of the mine that operated at this site is listed here. If two or more seams have been mined at this site, then it is possible that the mining was done by two or more mines.

Return to Form

9. The operator that mined the coal at this site is listed here. Many mines have been operated by different owners through the years. It is possible for different sites to have been mined by the same mine but by different operators.

Return to Form

10. Many of the newer mines have the surface properties and structures (houses, barns, shops, etc.) identified by ID numbers. If the house or property being researched was identified on a mine map, then the ID number is listed in these spaces.

Return to Form

11. The surface elevation is the elevation of the ground surface for the site being researched. This number refers to the number of feet above sea level. This elevation is generally considered to be accurate within + 10 ft.

Return to Form

12. The coal seam elevation is the elevation of the bottom of the coal seam being researched. This is also measured feet above sea level. This elevation could have an error as high as + 10 ft. or as little as + 0.5 ft. depending on the level of detail found in the mine maps available for this site.

Return to Form

13. The cover (overburden) gives the depth (in ft.) from the surface to the mine void. This is calculated by subtracting the coal seam elevation from the surface elevation. For the Pittsburgh coal seam of PA, the depth of cover could range anywhere from 0 ft. to as much as 1000 ft.

Return to Form

14. If the site being researched has been undermined, then the most recent date of mining below the site is noted on the report form.

Return to Form

15. The status of mining at the site being researched is indicated in this section. If "Coal Seam Non-Existent" is indicated, then it could mean that the site is not located within the coal fields of PA, or that the surface elevation for this site is below the elevation of the coal seam that was researched. "Future Possibility" is used for an area that is currently permitted, but where mining has not yet occurred.

Return to Form

16. The person researching the site will usually include additional information about the site being researched to further clarify what they found.

Return to Form

17. Any references sources that were checked in the course of researching the site, will be indicated whether or not they actually provided the researcher with any pertinent information.

Return to Form

18. The actual file, microfilm card, or book reference where the mining information was actually found is listed on this line.

Return to Form

19. The researcher signs and dates the report when they are done.
