Preparation Instructions
This specification is compiled by the former Ministry of Coal Industry in accordance with the requirements of the former State Planning Commission's Document No. [1986] 250, and is jointly compiled by production, construction, scientific research, universities, exploration, publishing and other units.
During the compilation process, the specification compilation team conducted extensive investigations and studies, carefully summarized the experience of construction and acceptance of newly built open-pit coal mines since the founding of the People's Republic of China, absorbed mature scientific research results, and drew on relevant advanced laws and regulations from abroad, and widely solicited opinions from relevant units across the country. Finally, our ministry reviewed and finalized the draft together with relevant departments. In view of the fact that this specification is compiled for the first time, if any units find the need for modification and supplementation during the implementation process, please combine engineering practice and scientific research, carefully accumulate information and summarize experience, and send special opinions and information to the National Standard Management Group of "Open-pit Coal Mine Engineering Construction and Acceptance Specifications" of the Open-pit Department of the Infrastructure Bureau of China National Coal Mine Corporation for revision reference.
