This specification is applicable to the design of new or expanded large and medium-sized chemical mine shaft and tunnel engineering. It can be used as a reference for small chemical mines. This specification summarizes the practical experience of chemical mine shaft and tunnel engineering design for decades; reflects the characteristics and advanced technical level and achievements of chemical mines; actively draws on advanced technologies at home and abroad and relevant technical standards, specifications and regulations of the same industry: it is compiled in accordance with the principle of combining reality, mature technology, safety and reliability. Especially in the technical aspects of trackless ramps, anchor spraying support, shaft and tunnel grouting, etc., there are refinements and innovations.
This specification has a high technical level, applicability, reliability and safety. It will play a positive role in realizing the standardization of chemical mine design, improving the design level, ensuring the design quality and engineering construction quality, and promoting the implementation of ISO9000 series standards in the chemical mine design industry.
This specification is interpreted and managed by the National Chemical Mine Design Technology Center. Due to the limitations of the level and experience of this station, shortcomings are inevitable. If any units have any questions or comments during implementation, please contact the central station in a timely manner so that it can be revised and improved in the future (No. 51, Chaoyang West Road, Lianyungang City, Jiangsu Province, Postal Code 222004).
