Abstract

The invention relates to the technical field of germanium resource exploration, and discloses a drilling layout method for coal-type germanium deposit exploration. Firstly, based on coalfield exploration data, the positions of existing germanium mineralization holes and faults within the exploration range are obtained; Then, based on the position of the existing germanium mineralized hole and the position of the fault, a plurality of first drill holes are arranged around the fault; then, each nth drill hole is cored to confirm that the nth drill hole is the nth mineralized hole , multiple n+1th drill holes are arranged around the nth mineralized hole, and n starts to accumulate from 1; until the n+1th drill hole reaches the boundary of the exploration range or the n+1th drill hole is a non-mineralized hole . The drilling layout method sets drilling holes according to the mineralization characteristics of coal-type germanium deposits, increases the layout density of drill holes in key areas, improves the control degree within the exploration range of coal-type germanium deposits, increases exploration accuracy, and reduces unnecessary drilling. settings, reducing exploration costs.

Description

technical field [0001] The invention relates to the technical field of germanium resource exploration, in particular to a drilling arrangement method for coal-type germanium deposit exploration. Background technique [0002] Coal-type metal deposits refer to coal seams, gangue or surrounding rocks of coal seams that are highly enriched in rare metals in coal-bearing rock series under specific geological processes and are suitable for mining and utilization under current technical and economic conditions. Coal-type germanium deposits are the main source of germanium metal at present. At present, the main exploration method for coal-type germanium deposits is to find favorable areas and arrange germanium exploration drill holes on the basis of combing the germanium mineralization points found in coal field exploration. The latest research shows that the genetic mechanism of germanium enrichment and mineralization in coal is roughly as follows: underground hot water rich in ge...
