Foreword
“Coal Resource Geological Exploration Specifications” issued by National Commission of
Mineral Reserves in December 1986 and “Peat Resources Geological Exploration
Specifications” (trail operation) that were jointly issued by Ministry of Geology and Mineral
Resources and Ministry of Coal Industry come into force (trail) have played active
promoting roles in the coal and peat exploration.
To enable coal and peat explorations to comply with the social and economic development
requirements in China as well as consistent with GB/T 17766-1999 “Solid Mineral
Resources/Reserves Classification”, it is necessary to revise “Coal Resource Geological
Exploration Specifications” and “Peat Resources Geological Exploration Specifications”
(trail operation).
This Standard is formulated on the basis of the summary of experiences getting from coal,
peat geological exploration and the collection of opinions get from public solicitation,
discussion and revision. Since the date of this Standard coming into force, “Coal Resource
Geological Exploration Specifications” issued by National Commission of Mineral
Reserves and “Peat Resources Geological Exploration Specifications” (trail operation)
that were jointly issued by Ministry of Geology and Mineral Resources and Ministry of
Coal Industry have been abolished.
Annex A in this Standard is normative.
Annex B, C, D, E, F, G, H, I, and J in this Standard are informative.
This Standard was proposed by Ministry of Land and Resources of the People’s Republic
of China.
This Standard shall be under the jurisdiction of National Technical Committee on
Geological Mines of Standardization Administration of China.
Drafting organization of this Standard. China National Administration of Coal Geology
Drafting staffs of this Standard. NI Bin, ZHANG Ziguang, LIN Dayang, GAO Honglie, SHI
Zuozhou, QIAN Dadu, TIAN Shaodong and SONG Quanxiang.
This Standard shall be interpreted by Ministry of Land and Resources of the People’s
Republic of China.
Specification for coal, peat exploration
1 Scope
