Recently，The ribbon-cutting ceremony for the completion of the delivery of the 1350-meter Sany Heavy Industry Wet Shotcrete Mixing Station in the third mining area, which was constructed by Jinchang Project Department of Jinchuan Group，Officially put into use！After a successful run，It is estimated that more than 900000 yuan of labor and material costs can be saved annually.。

After the delivery ceremony，The leader of Jinchuan Company pressed the start button of the underground wet shotcrete mixing station.，Speed up with the roar of the machine，The concrete produced by the system for the first time is transported to the construction site with professional vehicles.。

Sany Wet Shotcrete Mixing Plant，It mainly supplies materials for underground wet shotcrete construction and concrete pouring.，Gradually realize the centralized management of underground concrete materials、Mechanized mixing and mass production，Improve the quality standardization level，Guarantee the quality of concrete mix proportion。

It is understood that，March 2023，941 meters underground in the second mining area of Jinchuan Group，Sany Heavy Industry Concrete Mixing Station Completed Acceptance and Put into Operation。The average production capacity of the mixing station is 120 cubic meters./Hour，Automatic feeding is available、Programmed equipment、Multi-device interactive operation and other intelligent functions，It is also the first underground Sany Heavy Industry wet shotcrete mixing station put into use in China.。

This time，The underground wet shotcrete mixing station is located at 1350 meters underground in the third mining area.，After entering the depth，Construction is becoming more and more difficult，Roadway deformation and cracking caused by high geostress are serious.、The repair cost is high、Ventilation is difficult、Longer transportation distance leads to lower and lower construction efficiency，At the same time, it also faces the problems of poor construction environment caused by dry spraying technology.。Promote mechanized construction represented by wet spraying technology，It is an important breakthrough to solve these problems.。

Sany Heavy Industry attaches great importance to this project.，Draw lessons from the successful construction experience of Sanyi wet shotcrete mixing station on the ground，From Planning to Construction，After many discussions and demonstrations,，Develop detailed work list and responsibility matrix，Promote the construction in strict accordance with the requirements of site standardization management。Lan Ting, chairman of Sany Heavy Industry Gansu Hongchang, requested at the command site.：“During the construction of the mixing plant，The service system should set up a responsibility group as soon as possible.，Overcoming the problems of limited underground operation space and difficult equipment installation，Ensure that the mixing plant is installed in place in advance，Three senior service engineers from the province are stationed in the mining area to provide special services.，The installation department set up a technical team for underground installation.，Master the operation process in the shortest time，Complete technical training for customers in the fastest time”。

 During the successful commissioning of the underground wet spraying mixing station of No.3 Coal Mine，Jinchuan Group responsible person said.： “This is a new technological revolution.，It is also a breakthrough for Sany to establish various configuration requirements of wet shotcrete mixing station underground.，Sany Wet Shotcrete Mixing Station takes excellent design concept and advanced technology as its core.，Designed to produce up to 90 percentm³/h，It can realize dynamic measurement from materials.、Precise ingredients、Fficient discharge、All-round automatic process control from strong stirring to smooth discharge。What is more worth mentioning is that，High flexibility of the mixing system，According to the specific requirements of different underground working faces，Adjusting the strength ratio of the slurry in real times，While ensuring the quality of construction，Significantly improve operational efficiency”。

A construction worker who works underground all the year round said.：“Operation of Sany Heavy Industry's Underground Wet Blasting Mixing Station，Make the speed of process guniting in the mining area fast、High quality，Safety factor in construction、Production efficiency and working environment have been greatly improved.，Many people work in the city above the ground.，We work in the dungeons.，It reduces our labor intensity to go down and up the mine every day.，Going to work is no longer dusty.”。

Future，Sany Heavy Industry will take the construction of smart mines as an opportunity，Actively promote new technologies、New Technology、The new equipment is used in a variety of production sites of customers.，Give full play to its own research and development、Advantages of manufacturing and after-sales services，Actively provide standardization、Specialization、Customized construction services，Hand in hand to complete Jinchuan Group“Mechanized replacement、Automation reduces personnel、Intelligent unmanned”Business objectives，Promote the two sides to work together.、Mutual benefit and win-win。
