The Coal Mines Act 1911 amended and consolidated legislation in the United Kingdom related to collieries. A series of mine disasters in the 19th and early-20th centuries had led to commissions of enquiry and legislation to improve mining safety. The 1911 Act, sponsored by Winston Churchill, was passed by the Liberal government of H. H. Asquith. It built on earlier regulations and provided for many improvement to safety and other aspects of the coal mining industry. An important aspect was that mine owners were required to ensure there were mines rescue stations near each colliery with equipped and trained staff. Although amended several times, it was the main legislation governing coal mining for many years.
