In the method according to the invention and the arrangement or according to the invention for extracting extraction products in underground mining operations using the caving method, the extraction products () collapsing in an upper gate area () are extracted via at least one extraction funnel () or the like into an extraction path () driven below the gate and are transported away therein by means of an extraction conveyor (). According to the invention the extraction funnels () are arranged laterally beside the extraction conveyor () and lead at their lower end into a ramp surface () inclined towards the extraction conveyor, the extraction products extracted from the gate through the extraction funnels being transported slidingly over the inclined ramp surface to the extraction conveyor. The inclined ramp surface is preferably formed by a loading ramp () which is so arranged in an extraction chamber () branching off laterally from the extraction path that its one end (), disposed higher, is located below the extraction funnel and its other end (), disposed lower, forms an outlet () towards the extraction conveyor.
