Pinge
deepening in the terrain created by mining activities

A Pinge ([ˈpɪŋə], plural: Pingen) or Binge ('binger') is the name given in German-speaking Europe to a wedge-, ditch- or funnel-shaped depression in the terrain caused by mining activity. This depression or sinkhole is frequently caused by the collapse of old underground mine workings that are close to the Earth's surface. Unlike natural landforms, a Pinge is a direct result of human activity. The term has no direct equivalent in English, but may be translated as mining sinkhole, mine slump or, in some cases, as glory hole.
Origin of the word
In the original sense of the word, the mining terms Pinge or Binge go back to the activity known as pingen, which meant something like 'prospecting'. An aufgepingter lode was one near the surface of the ground. The Pinge was therefore like a primitive open-pit mine.
Subsequently, the term was transferred to the funnel-shaped depressions that formed at the surface above filled or collapsed mineshafts. In lode mining, shafts and pits followed the strike of the lode and left behind the typical lines of Pingen (Pingenzüge) associated with medieval mining that may still be seen, for example, in the Thuringian Forest, the Upper Harz Mountains, the Ore Mountains and the Eschweiler area in central Europe.
Later on, the term Pinge was applied to many kinds of depression left in the terrain as a result of mining activity, including the holes left by open-cast pits in surface mining or the cave-ins above underground mines.
Begin with the source’s own compact description: “Pinge” is deepening in the terrain created by mining activities. The dossier treats that line as a proposition to test through Pinge, deepening and terrain, not as a finished interpretation.
Why this record matters
The phrase “deepening in the terrain created by mining activities” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 14, 2026. The linked authority identifier is Q1183485. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
