We plant approximately 65,000 trees every year, create new hedgerows and waterways and provide environments rich in biodiversity, tailored to local wildlife needs The UK's coal reserves have been extensively mapped and recorded over the years and our challenge is to extract coal from surface mines using methods that are both commercially viable and environmentally sensitive Unlike deep mining, where shafts are sunk to depths of up to 800 metres or more, our surface sites extract coal from depths of between 40 to 150 metres
