The discovery of #coal in #Pictou County is usually attributed to Reverend James McGregor who found it on the East River in 1798. MacGregor, who came to Pictou from Scotland in 1786, had a coal fire burning in his home – a novelty at the time - when he entertained... #nspoli
...the political candidates the year before the 1799 provincial election.
John McKay was the first person given a lease to mine #Pictou#coal but it didn’t go entirely well for him. He was given permission in 1807 to mine on his father’s farm... #nspoli#cdnpoli#NovaScotia
...and a few years later coal became scarce – and more than doubled in price - during the War of 1812. McKay sold #coal to #Halifax for use by the navy, garrison and residents. He invested heavily in his operations but ran into trouble when the war ended in 1815... #nspoli
...and #coal’s price dropped. He was eventually thrown in prison for his debts.
His lease later came to be owned by Edward Mortimer, George Smith, and Adam Carr until 1827 when the General Mining Association took over the coalfield as part of its 30-year monopoly... #nspoli
...on most #coal in Nova Scotia. The GMA also bought Reverend MacGregor’s 800-acre farm for £1,150 for its coal.
The GMA quickly developed coal operations at Albion Mines, a town the company founded and which was renamed Stellarton in 1870. #nspoli#cdnpoli#NovaScotia
Several other mines were also worked during the 1800s. Fires and explosions caused several mines to close, although some reopened at later dates.
The GMA invested heavily and brought the industrial revolution to Nova Scotia. #nspoli#cdnpoli#NovaScotia
Our first steam engines were built by the GMA to power pit hoists and pumps, and to drive #coal ships. #NovaScotia's first railway (meaning it was powered by steam, not horses) was the Albion Mines Railway, built in 1839 to haul coal from the #Stellarton mines to docks... #nspoli
...in #Pictou Harbour. It was only the second steam railway in Canada.
The GMA also helped professionalize (by the standards of the day) Nova Scotia’s mining industry by founding permanent mining communities and bringing skilled British miners to the province. #nspoli#NovaScotia
In 1872, the GMA sold all its #Pictou operations to the Halifax Company and withdrew from the coalfield.
In 1886 three of the four major coal companies operating in the Pictou coalfield - #Halifax, Vale and Acadia - merged to form the new Acadia Coal Company. #nspoli#NovaScotia
Acadia was the main coal producer in #Pictou County until 1966. Over that time it became a subsidiary of #NovaScotia Steel and Coal, which in turn was a subsidiary of British Empire Steel Corporation (BESCO) and later the Dominion Steel and Coal Corporation (DOSCO). #nspoli
Mining continued sporadically in many different mines into the 1900s with most operations creasing by 1960. #nspoli#cdnpoli#NovaScotia
The only #coal mine operating in the #Pictou Coalfield today is the #Stellarton surface mine which is fixing subsidence issues caused by 200 years of pick-and-shovel mining, including many bootleg mines. #nspoli#cdnpoli#NovaScotia
The mine is stabilizing the land so it can be used for development, while also creating jobs for #NovaScotians and providing fuel to Nova Scotia Power. #nspoli#cdnpoli#NovaScotia
Unfortunately, the #Pictou Coalfield was known to be particularly “gassy” and this made it a difficult coalfield to mine safely underground.
Methane is a gas formed as organic matter decomposes in the absence of oxygen, such as when plants die in wetlands, marshes and swamps...
...the sorts of places where coal usually forms. The methane is trapped in the coal as it forms and is released as coal is mined.
Methane is a greenhouse gas. It is also combustible, which is why it has always been a safety challenge in underground coal mines. #nspoli#cdnpoli
It is essential that it be vented out of a mine, so it cannot pool and trigger fires and explosions. The Westray mine disaster, in which 26 miners were killed on May 9, 1992, was partly caused by the inadequate ventilation of methane. #nspoli#cdnpoli#NovaScotia
Westray was on the Foord Seam which is the thickest coal seam in Nova Scotia - 13.4 metres thick in places – and a tremendous source of fuel and economic activity. However, every mine that opened in the Foord seam ended in fire or explosion. #nspoli#cdnpoli#NovaScotia
The #Mikmaq were aware of methane burning at outcrops and along the banks of the East River and apparently told ancient stories of fires and explosions that were linked to the #coal. In fact, the name #Pictou is said to have been derived from... #nspoli#cdnpoli#NovaScotia
...the #Mikmaq word Pictook meaning “an explosion of gas.” (Clergyman Silas Rand, who was born in 1810 in Cornwallis, NS, wrote a Mi’kmaq-English dictionary that suggested the name came from the escape of gas from coal around East River.) #nspoli#cdnpoli#NovaScotia

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.
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. #nspoli
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
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.
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.
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. #nspoli#cbpoli#novascotia#capebreton#nshistory
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
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
...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.
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
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
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
