INTERN TRAINING Data Collection
2
NMMR SYSTEM Each Map that enters the repository is inventoried, scanned, and put into the NMMR database. Information about the mine is collected from the map and input onto a data entry sheet by hand Information from the data entry sheet is then input into the digital database
3
The Data Entry Sheet
5
Document Number A document number must have 6 digits 324355 005475 447988 501232 903014 000000’s Anthracite coal fields of PA 300000’s Most states East of the Mississippi 400000’s States west of the Mississippi 500000’s NW corner of the country. Not active anymore 700000’s Kentucky 800000’s Virginia 900000’s West Virginia The document numbers represent different states and areas of the country:
6
Number of Scenes A scene is either one part of a whole map Map is too large to scan only one image and needs broken into sections. OR Map is part of a sequence of maps Monthly update reports Scene Number will add 2 additional digits onto a document number for a total of 8 digits. If only one scene add 00 to end of document number 32435500 01, 02, 03, 04, 05, etc 99 scenes maximum
7
Cross-Reference Number Any signifying set of numbers of letters found on the map. Put there by the original source.
8
YEAR The Year the mine map was created. Maps might have other years stamped on them from offices they’ve gone through – look for the year the mine map was created and ignore all other dates.
10
State Obtain 2 letter state abbreviation from map or map source. Certain states are known for certain commodities Only Coal in PA – no metals mined. List two states if mine takes place close to a state border Border of PA and WV Border of WV and KY
11
County Sometimes the county or counties are listed on the map, most often they are not. Use internet resources to search within a state for the right county where the mine is located. Use a search engine to query surface features seen on the map such as rivers, streams, creeks or even township names Open up the mine maps database and use the drop-down menus to search.
12
Quad Quad refers to USGS 7.5 minute quadrangle map - a USGS topographic map the covers an area of approximately 60 square miles Each county contains several quads – sometimes more than one county will share a quad. The easiest way to search for quads is through topoquest.com. Search by state and location or by lat/long.
14
Map Source Who we received the map from They sent the maps to our office Colorado School of Mines They physically brought the maps to our office Penn-Virginia Coal Company
15
Company The owner of the mine NOT to be confused with the engineer who drew the map Company name is found written on the map Ex. Consolidated Coal Co. Ex. Crown Coal and Coke Co. Ex. Eagle Picher Mining and Smelting Co
16
Mine Name “Colliery” and “Colly” are other names for mine. Tamaqua Colliery Most of the time the mine name is listed prominently on the map, sometimes you may need to search for it. Located in the title or key of the map or located by entrance of mine in the midst of the mine workings. If there are multiple mines seen on the same map, each mine name will be a SEPARATE DATA SHEET. No. 1, No. 2, No. 3 Use the name of the company and a number sign (hashtag symbol) Consolidated # 2
18
Mine Type Underground Look for underground workings Surface Look for signs of surface mining Surface in title of map Combined Both underground and surface mining N/A If you’re not sure
19
MSHA ID You will know when you are working with an MSHA map. The ID will be apparent.
20
Certified Unless the map explicitly states it is certified – circle NO
21
Final Scan Unless it is explicitly stated on the map – Circle UNKNOWN
22
Aperture Card If you are scanning a map, then the document number does not yet have an aperture card made for it. If you are filling out a data entry sheet for a map that has already been scanned, check the drawers to see if it has a matching aperture card.
23
Scanned If you are scanning the map, circle YES
24
Color
26
Commodity The map will usually tell you what is being mined Ex. Coal, Clay, Zinc, Lead, Gold Location will give context clues Anthracite only mined in certain locations Gold would not be found in PA
28
Coal Bed The bed, vein, or seam where the coal is being extracted from. Think of the mine map in 3D Vertically there are layers where coal is being mined, each layer is considered a bed, vein, or seam The Coal bed is usually listed on the map in the key or along the bed boundry Examples: Upper Freeport, Powellton, Orchard, etc.
30
Geolocating a Mine Map It is really important to take the time to geolocate mines as accurately as possible. Searching for locations can be time consuming – use helpful internet search tools and any features on the map to find coordinates Streams, rivers, streets, intersections, cemeteries, township lines, etc. Use google maps or USGS Quad to match surface features and extract coordinates.
31
Degrees, Minutes, Seconds 1˚= 60” = 3600’ Since we only work Nationally: Lat: Degrees: 18-85 Minutes: 0-59 Seconds: 0- 60 Long: Degrees: 65-180 Minutes: 0-59 Seconds: 0-60 It is OK to represent Longitude as a positive number Example: Pittsburgh 40˚ 23’ 26”N 79˚ 58’ 35”W
33
Decimal Degrees Expresses lat/long as decimal fractions Longitude MUST have negative sign!!! Example: Pittsburgh 40.439722 -79.976389 EITHER DD OF DMS IS FINE AS LONG AS COORDINATES ARE FILLED OUT AS ACCURATELY AS POSSIBLE.
35
Datum
36
UTM ZONE
38
Scale Treat scale as 1” = ____ ‘ There will be a scale bar on the map OR scale will be written with map key/title You may have to search/scour the map to find this information Example: 1”= 100’ Special Circumstance: Multiple Scales Vertical and Horizontal Put vertical scale on scale line and make note of horizontal scale in notes. Two separate drawings on same page Fill out two separate data entry sheets Same drawing-different sizes (zoomed in) Write this in notes
39
Map Condition Circle GOOD if the map is in excellent/pristine condition. All features are easily seen and all data on the map is easily read. Circle POOR if map is falling apart or impossible to read. Most maps are FAIR – somewhere in the middle of GOOD and POOR
41
Township, Range, Section Abbreviated TRS Created by the Public Land Survey System (PLS) Uses Prime Meridians and Baselines to create grids. Township and Range numbers are assigned to these grids. Inside Each Township and range are 36 sections. Each section is 1 square mile. Map will state TRS numbers Use Earthpoint.us to find coordinates from TRS data
43
TRS Grid with Section Numbers RANGERANGE TOWNSHIP 654321 789101112 181716151413 192021222324 302928272625 313233343536 1 mi
45
Adjacent Mines Any other mines listed on the map should also be written in as adjacent mines A SEPARATE DATA SHEET MUST BE CREATED FOR ALL MINES LISTED ON THE MAP. Example: Franklin Mine, Miller Mine, and Bethlehem Mine #31 are all listed on the map, they will all receive their own data entry sheet even if all other information on data sheet is the same. All mines listed on map will receive their own data entry sheet EVEN IF the map title lists only the Franklin Mine.
46
OTHER INFO The map must be inspected carefully to complete this checklist.
47
OTHER INFO Assay the testing of a metal or ore to determine its ingredients and quality. Listed in chart form on the map
48
ASSAYS
49
OTHER INFO Elevation Elevations listed INSIDE THE MINE Contour lines Numbers marked with elevation or EL Thickness Coal Bed Thickness Sometimes found in chart form or number with word thick after Crop Line Outcrop boundry Most of the times follows surface contour lines Will usually have name of outcrop
50
X-Section/Cross Section
51
OTHER INFO Water Any water lines in the mine? Drill Holes Labeled DH or DDH Map key will likely show you what to look for – usually a small dot. Examples: Gas Wells Look a lot like drill holes Are labeled differently on the map Are labeled differently in the map key
52
Geo Description Anything that defines the geolocated point. River, stream, intersection, street, town, city, borough, etc
54
Location Assurance IF you are certain you found the exact lat/long for the mine then circle APPROXIMATE TRS data Defining surface features IF you are in the right township or general vicinity of the mine but unsure of the exact location of the mine circle UNCERTAIN Township/Town/City/Borough IF you are unable to pull any locational data from the map, circle UNKNOWN Double check your coordinates! Does the longitude have a negative sign under DD?
55
Remarks Write description WORD FOR WORD if there is one on the map. ANY other features OR anything else about this map.
57
Back side of data entry sheet ALL information must be extracted off of the mine map and onto the data entry sheet. We do not keep most of the maps that go through our office, they are here for a very short time, even though we retain scans of all maps it is important to pull all information off the front and back of the map when it gets here. USE THE BACK OF THE DATA ENTRY SHEET IF YOU NEED TO. IF the remarks section is too small for you to write the entire description of map NO EXCUSES
