introduction
DZ/T 0175-1997 is a coal field awarded in 1979 by the Ministry of Coal for the purpose of adapting to the geological mapping work in geological exploration of coal fields.
Geological mapping procedures (1.50000 1.25000 1.10000.1.5000) and the "large-scale aviation geology" issued in 1983
Based on the measurement procedures, we have summarized many years of practical experience and made full consideration of the current development and technological progress.
After the implementation of DZ/T 0175-1997, there were GB/T 13908-2002, DZ/T 0215-2002 and "Coal and Peat Geological Survey Regulations".
Fan's implementation guidance and other related standards are issued and implemented, thus requiring national standards and industry standards in this standard and geological exploration field.
Quasi-matching. At the same time, in recent years, the technical means related to geological mapping work has been greatly developed, and the practice of geological mapping has added new ideas.
Inspection, so it is necessary to make corresponding adjustments and modifications to DZ/T 0175-1997.
