Office of Surface Mining Reclamation and Enforcement (OSM)

Department of the Interior (DOI)

A resource for geological & mining

information:

The National Mine Map Repository,

Department of the Interior

� Originally maintained by the Bureau of Mines

� 2 facilities east of the Mississippi River: Pittsburgh (states east of the Mississippi) and Wilkes-Barre, Pennsylvania (anthracite fields)

� 2 facilities west of the Mississippi River: Denver, Colorado’s Intermountain Field Operation Center (west of the Mississippi + Minnesota & Louisiana except for the northwest states) and Spokane, Washington (northwestern states and California)

� Responsibility for the Pittsburgh and Wilkes-Barre Repositories was transferred to the Office of Surface Mining Reclamation & Enforcement in 1982

� BOM dissolved in 1996 & all remaining BOM archive maps were transferred to OSM’s Pittsburgh office

� In 2011 the Wilkes-Barre Mine Map Repository was closed and the archive was transferred to the NMMR in Pittsburgh

� NMMR’s index system is a significant mining information reference

� All info archived at the NMMR is available to the public

� The archives are increasingly being copied into easy-to-reference digital format (though microfilm is still required for archival purposes)

Currently NMMR currently uses two types of storage and archiving.

1) Digitally – utilizing 465TB of storage capacity

2) Microfilm – Aperture Cards

Maps

Maps2

At present we have digital storage capacity of 105TB with another

360TB ready to be activated for a total of 465TB

We use Nexsan SATABeasts for the current 105TB storage capacity

The other 360TB will come from 2 180TB Nexsan E60 systems.

Maps – 21TB for use of the operation of the Mine Map

Maps 2 – 21TB Store data received from states from Co-ops etc.

8.8TB 290000 files – Maps, georeferenced maps, databases

Free off-site digital storage is available

at the NMMR

Linear Tape-Open (or LTO) is a magnetic tape data storage

technology originally developed in the late 1990s as an alternative to

the magnetic tape formats that were available at the time.

Half-inch (1⁄2-inch) magnetic tape has been used for data storage for

more than 50 years. In the mid 1980s, companies began putting this

kind of tape into a single reel, enclosed cartridge.

Tape Backup

At present OSM uses LTO 4 as its tape back up system

1) First introduced in 2007

2) Twice the speed and capacity as the LTO 3 system

a) Capacity per tape 800 GB

b) Data transfer rate of 120MB/s

We plan to migrate to LTO 5 in the near future

1) Introduced in 2010

2) Almost twice the capacity of the LTO 4 1.5TB

3) Increased transfer rate to 140MB/s

4) Partition feature allows tape to be split into 2 writable areas

We currently backup the storage devices once a week with the

tapes being sent off-site.

When a map is received…

� Data is extracted from the map

� Then the mine map is scanned

� Digital map scan is sent into digital storage and map data is entered in the database

� Scan transferred onto microfilm & mounted onto aperture card

� Aperture card is placed into archive/catalog →→

� Copy of scan sent to donor (if requested)

� Map returned to donor or sent to off-site storage

NMMR Document Numbering System

The document numbers represent different states and areas of theCounty:1.000000’s Anthracite coal fields of PA2.300000’s Most states east of the Mississippi 3.400000’s States west of the Mississippi4.500000’s States in the northwest corner of the County, these numbers were assigned by the Spokane office of BOM not active 5.700000’s Kentucky6.800000’s Virginia 7.900000’s West Virginia

Over 140,000 document numbers in use

We have completed transferring the microfilm rolls from both theDenver and Spokane Offices of the BOM to aperture cards.

These maps now can be scanned.

The old FoxPro database has been moved to Sequel

New Database

Numerous new fields have been added

NMMR Data Entry Screen

NMMR mine map search page

A mine map can be searched for by any one of the parameters on the screen. The results can be exported to an Excel spreadsheet.
