The Sullivan Creek #coal mine, before and after!
It's one of several mines reclaimed around #AlderPoint #CapeBreton in the late 1900s/early 2000s - examples of how mining makes temporary use of land and then land can be used other ways.
#nspoli #cbpoli #novascotia @JaimeBattiste ImageImage
The first mine in the area was the Scotia Mine, or #NovaScotia Steel & Coal Company No. 4 Colliery, on Toronto Road, which operated on the Sydney Main (Harbour) Seam from 1915 to 1921.
#nspoli #cbpoli #novascotia @JaimeBattiste ImageImage
Coal quality and structural issues (including water inflow) plague the Harbour Seam west of Florence so upon closure of the colliery, production on the Harbour Seam was limited to the Company’s No. 3 Colliery in Florence, which had opened in 1902...
#nspoli #cbpoli #novascotia ImageImage
...and the Princess mine in #SydneyMines (see our history of the Princess Mine at and our history of Sydney Mines at ).
#nspoli #cbpoli #novascotia #capebreton ImageImage
In 1920 the Nova Scotia Steel & Coal Company opened the Alexander (aka Alexandra in some reports) Colliery, on the Lloyd Cove Seam, at Little Pond, but it closed in 1923.
#nspoli #cbpoli #novascotia #capebreton ImageImage
The colliery was entirely land-based, but a plan was in place to mine the coal offshore through shafts to be located near the shoreline at Alder Point. That never happened. In 1921 the Company became a wholly owned subsidiary of the British Empire Steel & Coal Company, aka BESCO. ImageImage
In 1947 the Old Sydney Collieries Ltd. No. 7 Mine was opened at Little Pond, to work the Lloyd Cove Seam through a series of four large surface mines, running from north of Schoolhouse Road, southeast to the shoreline, a distance of almost 2 kms.
#nspoli #cbpoli #novascotia ImageImage
This company was a subsidiary of the Nova Scotia Steel & Coal Company, which was a subsidiary of BESCO.
#nspoli #cbpoli #novascotia #capebreton ImageImage
Little Pond is where the first trials of the “DOSCO Miner” took place, a machine with a large rotating steel drum and teeth that scraped coal from the seam and carried it out of the tunnel on conveyor belts.
#nspoli #cbpoli #novascotia #capebreton ImageImage
The DOSCO Miner would ultimately be used underground at all Dominion Coal Company mines and similar “continuous miner” machines are used widely today. In 1950 a small underground operation was started, the slopes being at the base of the surface mine near the intersection... ImageImage
...of the Schoolhouse and Little Pond Roads. The mine closed in 1956.
Illegal or bootleg mining is known to have been conducted on the Lloyd Cove Seam between Little Pond and Alder Point since the 1930s, but it was not until 1973 that the #CapeBreton Development Corporation... ImageImage
...opened a surface mine near the tip of Alder Point on the Lloyd Cove Seam. Just over 100,000 tonnes were removed by 1974 at which time production ceased.
#nspoli #cbpoli #novascotia #capebreton Image
Other surface mines would follow, including Cape Crushing’s operation at Merritt Point, just South of the former Alder Point operation (Lloyd Cove Seam), which started in 1991 and closed in 2005.
#nspoli #cbpoli #novascotia #capebreton Image
Brogan Mining Company operated at Sullivan Creek, on the Little Pond Road from 1993 to 1998, extracting approximately 60,000 tonnes. This mine worked the near surface coal left from the most southerly underground operations of the Scotia (No. 4) Colliery.
#nspoli #cbpoli ImageImage
Brogan also operated at Toronto Road on the Sydney Main (Harbour) and Hub seams from 1995 to 1999.
#nspoli #cbpoli #novascotia #capebreton Image
Brogan operated at Little Pond on the site of the former Alexander and No. 7 mines from 1999 to 2003, subsequently moving North to Merritt Point, immediately South of the Cape Crushing operation, producing for a short time, 2004-2005.
#nspoli #cbpoli #novascotia #capebreton ImageImage
The Alder Point, Little Pond and Toronto Road sites, along with the Point Aconi surface coal mine, were part of a study of reclamation practices from 2006-2012 (novascotia.ca/natr/meb/data/…).
#nspoli #cbpoli #novascotia #capebreton Image
The study looked at how soil can be made more accessible to pioneer plants to become established; how to preserve living organisms in the organic layer; how to create micro-habitats for seed germination and erosion control; how to encourage biodiversity...
#nspoli #cbpoli ImageImage
...and how best to encourage the spread of vegetation on a reclaimed site.
The pictures show how mines/quarries can be transformed from operational sites to natural spaces.

@nsgov announced new rebates for electric vehicles yesterday. Mining makes #greentech like electric cars possible because they are mostly made of minerals and metals.
#nspoli @KeithIrvingNS @IainTRankin @NS_Energy_Mines @ns_environment @ChenderMLA @AllanMacMaster @MLAChuckPorter Image
For example, an e-car has 183 pounds of copper wiring in it because copper is used in every major component from the motor to the inverter and the electrical wiring. There is about four times more copper in an e-car than in a car with an internal combustion engine.
There are about 400 electric cars on Nova Scotia roads - a total of over 73,000 pounds of copper!
An electric car uses 25-50 grams of silver, so Nova Scotia’s 400 e-cars contain about 15,000 grams of it.

The Morris Street Engine House has been declared a municipal heritage property!
#Halifax’s Fire Station #2, as it is also called, was built 1907-08 of reinforced concrete.
Here's the story!
#nspoli @HFXFireHistory @HRMFireNews @hfxfire @HFXFirefighters @hfxgov @MikeSavageHFX
Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. (The terms cement and concrete are often used interchangeably, but cement is actually an ingredient of concrete...
#nspoli
...Cement is the glue that holds concrete together.)
Reinforced concrete means the concrete is poured over a frame, usually steel bars, that give the structure greater strength.

We love getting questions about mining, minerals and geology! We were asked about sinkholes and whether they are a risk when walking in the woods.
#nspoli #cbpoli #novascotia #capebreton @oxfordsinkhole ImageImage
The short answer is yes, sinkholes are real but no, they are not a major risk and should not prevent you from enjoying outdoor activities.
Most natural sinkholes are caused by groundwater naturally eroding rocks like gypsum, salt and limestone which are water-soluble.
#nspoli Image
The water erodes the rock, leaving an underground cavern. Eventually, the weight of the rock and earth above the cavern causes the sinkhole to form. Sinkholes can form either gradually (i.e. a small depression appears and perhaps grows larger over time) or by sudden collapse. Image

We love getting questions about mining, minerals and geology! We were asked about the historic #NewCampbellton coal mine in #VictoriaCounty.
#nspoli #cbpoli #novascotia #capebreton #nshistory
@JaimeBattiste ImageImage
The New Campbellton coal mine was opened in 1862 by Charles J. Campbell, a former Member of Parliament, Member of the Legislative Assembly and executive council member. The community had been named Kelly’s Cove but was changed to New Campbellton in 1862 in honour of Mr. Campbell. Image
A sample of New Campbellton’s coal was sent to the 1865 Dublin Exhibition and “was very favorably noticed by the Judges,” according to a report.

Mining built #NovaScotia!
#Halifax was founded in 1749 and its first court house is reported to have been built by 1754 on the northeastern corner of Buckingham + Argyle streets. After the building burned in 1789, the courts were temporarily housed in various buildings.
#nspoli ImageImage
In April 1851 a bill to provide Halifax with a county court house was passed. Mr. H.G. Hill, a prominent #Halifax architect, prepared a plan for a wooden building.
However, since the records of the county, wills, deeds and other papers of public office were...
#nspoli #novascotia Image
...to be stored in the court house, it was important that the building be fire-proof. Also, a number of serious fires in #Halifax in 1857 led to the passage of a bylaw that required large buildings be made of stone or brick, so Hill's plans for a wooden building were abandoned. Image

We love getting questions about mining, minerals and geology! We were asked if we know what these intriguing circles are in #Walton, #HantsCounty.

#nspoli #cbpoli #novascotia @MLAChuckPorter @EastHantsNS #easthants ImageImage
The person who asked isn’t the only one who has noticed the circles. With satellite images so easy to access on the Internet, others have also noticed them, including the excellent staff @NS_Energy_Mines.
#nspoli #cbpoli @MLAChuckPorter @EastHantsNS Image
They investigated them in the early 2000s, thinking they could be sand/mud volcanoes.
A sand volcano is a cone-shaped landform created by liquefied sand being expelled from underground onto the surface.
