DZ/T 0213-2002Specifications for metallurgic, chemical limestone and dolomite, cement-materials mineral exploration (English PDF)

1 Scope

This Standard specifies the degree of exploration study, exploration quality, classification and type condition of resources/reserves, estimation of resources/reserves, etc. for metallurgical, chemical limestone and dolomite, cement- material mineral (calcareous material, clay material, and siliceous material)1); and provides the deposit exploration type for analogy, and exploration engineering spacing for reference.

This Standard is applicable to the metallurgic, chemical limestone and dolomite, cement-materials mineral exploration, resource/reserves estimation; applicable to the acceptance and review for the exploration design and exploration result report of metallurgic, chemical limestone and dolomite, cement-material mineral; can also serve as the basis for assessing and estimating the mineral resources/reserves during the financing and the like activities of mining rights transferring, and mineral exploration and mining.

1) Cement-material mineral generally includes. calcareous material – limestone, argillaceous limestone, marble; clay material – clay, loess, mudstone, silt rock, shale, phyllite; siliceous material – sand, sandstone.

3 Target Tasks of Exploration

The exploration work can be divided into four phases, namely, pre-survey, general survey, detailed survey, and prospecting. The target tasks in each phase are as follows.

3.1 Pre-survey phase. through comprehensive study of geological data in the area, preliminary field observation, very small amount of engineering verification, analogy and prediction of the known deposit with the similar geological characteristics, propose the area with larger mineral resources potentials for the general survey.

3.2 General survey phase. through adopting outcrop inspection, geological mapping, limited number of sampling work, and the like field work against the area with larger mineral source potentials confirmed in the pre-survey phase, generally find out the geology and tectonics in the general survey area; generally understand the orebody shape, production condition, and quality characteristics; generally learn exploring technology of the deposit; conduct the mineral processing and separation analogy study; propose whether it is worth for the further detailed survey, and encircle the range for the detailed survey area.
