The company attaches great importance to the research and application of new technology, vigorously carries out the research on complete set of construction technology for high efficiency, safety and environmental protection of mine shaft and lane based on wet jet technology in Tongshan project, and won the second prize of "Tongling Nonferrous technology innovation achievement award" of the group company.

Since the introduction of Wet Shotcreting Technology in 2013, Tongshan project department has successively completed shotcreting support in the middle section of - 658m, - 613m, - 568m and - 523m, with a total length of more than 6000 meters, fully realizing parallel operation. In order to ensure the smooth production in January 2014, Tongshan mining company once required the project department to complete the support of the new auxiliary shaft-658m middle section of more than 1000m roadway within 40 days, which is a very difficult task. The project department adopts the wet spraying technology to support the tunnel and chamber permanently, which greatly improves the support efficiency. It only takes one month to complete the task, which is highly praised by the mine.
