On Apr 9, the《Code for design of ferrous metallurgical mines underground excavation engineering》chiefly developed (edited) by CIE has passed the professional review organized by China metallurgical construction association.

The code is the first standard for underground excavation engineering in the mining industry, and it was started in April of 2010. Due to lack of basic data and difficult editing, the whole development time is long. CIE and the participating development organizations like MCC Capital Engineering & Research Incorporation Qinhuangdao Co., Ltd., Fujian Maken Mining Co., Ltd., the 23th Metallurgical Construction Group Co., Ltd. of Minmetals and the Institute of Rock and Soil Mechanics, Chines Academy of Science etc. had completed the standard for comment by the end of October of 2014, and opinions were asked for publically at the website of China metallurgical construction association. In March of 2015, the standard for approval is completed.

In the code, the detailed specifications are made for drift and adit, inclined shaft, inclined slope, vertical shaft, shaft station, orepass loading system, underground (shaft) firefighting and underground safety signs etc. for ferrous metallurgical mines underground excavation (sinking and drifting) engineering design, filling the blanks of code for domestic ferrous metallurgical mines sinking and drifting engineering design, and all these will play active roles in improving the design quality and technical level of ferrous metallurgical mines sinking and drifting engineering and standardizing the engineering construction of ferrous metallurgical mines shaft and drifts.
