摘要： The invention relates to a method and to an arrangement device for extracting extraction products in underground mines in caving. According to the invention, extraction products (20) breaking into an upper coal face (10) are extracted by means of at least one extraction funnel (13) or similar, into an extraction path (14) disposed practically underneath the coal face and are evacuated in said extraction path by means of an extraction conveyor (15). According to the invention, the extraction funnels (13) are arranged next to the extraction conveyor (15) and lead into a ramp surface (17), which is inclined, towards the extraction conveyor, with the lower end thereof. The extraction products extracted from the coal face by the extraction funnels are slidingly transported to the extraction conveyor via the inclined surfaces. The inclined sloped surface is, preferably, formed by a charge ramp (22) which is arranged in an extraction chamber (16) which branches off in a lateral manner from the extraction path, such that one of the high-lying ends (19) thereof is disposed below the extraction funnel and the other low-lying end thereof (23) forms an outlet (21) leading to the extraction conveyor.
