Beneath a complex of waterfront townhouses and residences in Sydney lies the history of Australia’s deepest coal mine.<\/p>\n

What was once a working class, coal-fuelled borough is now some of the inner west’s most sought-after suburbs, with the median house price in Birchgrove and Balmain sitting around $3 million.<\/p>\n

But almost 130 years ago, this area of Sydney looked far different.<\/p>\n

“In those days, as opposed to today, the council was desperate to get any industry they could in the area to keep people employed,” Duncan MacAuslan, president of community heritage group the Balmain Association, said.<\/p>\n

Sydney’s coal mining history<\/p>\n

Located near Birchgrove Public School, Balmain Colliery was established after a seam of good coal was found via bores at Cremorne and Balmain.<\/p>\n

However, lower north shore residents were incensed at the idea of a coal mine in leafy Cremorne.<\/p>\n

“The north shore was already quite populated with artists and people as such. They did not want a coal mine in their back garden,” Mr MacAuslan said.<\/p>\n

“So one of the Balmain councillors said, ‘Well we have a spare bit of land here’.”<\/p>\n

It produced coal in periods between 1897 and 1931, and natural gases around 1937 to 1950, though not without deadly incidents.<\/p>\n

In 1900, six men were being lowered into a mine shaft over 500 metres deep via a bucket when it caught on a projection and tipped, causing five of the men to fall to their deaths.<\/p>\n

The men who died were aged in the range between 19 to 35.<\/p>\n

“The workers would just sit on the edge of the big bucket as it was going down into the shaft \u2014 they didn’t have any harnesses or a safety cage. The accident prompted the Mining Act to be amended,” Mr MacAuslan said.<\/p>\n

The amended legislation said mine shafts needed to have guide rails to prevent buckets from overturning.<\/p>\n

In preparation of a drilling site to locate natural gases in about 1933, two workers were killed in an explosion.<\/p>\n

Then in 1945, another gas explosion left three men dead.<\/p>\n

There were additional deaths reported at the colliery prior to 1900, though few details are known.<\/p>\n

Despite the poor safety and working conditions of the time, one of the colliery’s shafts struck coal at about 850 metres, with Balmain Colliery believed to be the deepest coal mine in Australia, according to the NSW Department of Primary Industries.<\/p>\n

For Mr MacAuslan, who emigrated from Scotland to Australia decades ago, he was drawn to Balmain and its surrounding suburbs for the pubs and heritage buildings.<\/p>\n

He would eventually live very, very close to the former Balmain Colliery. In fact, basically on top of it.<\/p>\n

“One of the former shafts would be about five or six metres behind my house,” Mr MacAuslan said.\"Duncan<\/p>\n

By the 1950s, Balmain Colliery’s two main mine shafts were filled in and sealed. A thick concrete slab was then poured on top, making it safe to reuse the land.<\/p>\n

In the late 1990s, a residential complex called Hopetoun Quays was built on top of the former mine site, with the luxury townhouses and terrace-style residences near the waterfront now often selling for a pretty penny.<\/p>\n

Bruce Swalwell, the architect behind the residential complex, said a lot of consideration went into the design.<\/p>\n

“The structural engineers had to be very mindful of the settlement of the building over the old coal mine area, and there was a lot of money spent to ensure the buildings that were on top were structurally sound,” he said.<\/p>\n

Mr Swalwell said honouring the suburb’s history and maintaining public access to the foreshore via a boardwalk and nearby park was crucial.<\/p>\n

“Keeping Birchgrove and Balmain at medium density was very important, rather than a proliferation of high-rise buildings,” he said.<\/p>\n

“It was the right urban pattern for the area, especially for the time.”<\/p>\n

Mr MacAuslan added: “Many locals are interested in Balmain and its heritage \u2014 there is lots to learn from history.”<\/p>\n","protected":false},"excerpt":{"rendered":"Beneath a complex of waterfront townhouses and residences in Sydney lies the history of Australia’s deepest coal mine.…\n","protected":false},"author":2,"featured_media":480485,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[243960,64,63,243955,243947,243941,243943,243954,243953,243949,243944,243948,243952,99,243950,243956,243957,243958,243959,243951,243942,116402,243946,243945],"class_list":["post-480484","post","type-post","status-publish","format-standard","has-post-thumbnail","category-business","tag-architect-bruce-swalwell","tag-au","tag-australia","tag-australia-mining-history","tag-australias-deepest-coal-mine","tag-balmain-coal-mine","tag-balmain-colliery","tag-balmain-colliery-deaths","tag-balmain-colliery-history","tag-balmain-history","tag-birchgrove-coal-mine","tag-birchgrove-history","tag-birchgrove-public-school","tag-business","tag-duncan-macauslan","tag-hopetoun-quays","tag-hopetoun-quays-birchgrove","tag-houses-above-coal-mines","tag-houses-on-top-of-coal-mines","tag-president-of-community-heritage-group-the-balmain-association","tag-sydney-colliery","tag-sydney-inner-west","tag-waterfront-residences-sydney","tag-waterfront-townhouses-sydney"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/480484","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=480484"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/480484\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/480485"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=480484"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=480484"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=480484"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
