PILLAR EXTRACTION USING CONTINUOUS MINERS. Overview. Now that longwall equipment has been developed to a stage where it is able to cope with most conditions satisfactorily, longwall mining is the most widely used method of secondary extraction. However, there are still mines and occasions where longwall mining is not suitable e.g.

We use contrast set mining, a form of discriminative pattern min-ing, to learn what distinguishes one group of crashes from another. Prior works focus on discretization to apply contrast mining to continuous data. We propose the first direct application of contrast learning to continuous data, without the need for discretization.
Jul 14, 2021 Spread the love 81 Interactions, 81 today The recent miner migration from China has been one of the most significant roadblocks to the Bitcoin ecosystem since its creation. The Chinese crackdown was first promoted as a reaction to increasing ESG concerns caused by miners energy consumption, but it involves much more. Its consequences have also been far-reaching,
