The first in China! Sany Step-type Anchor Digging and Transporting Machine was put into use in Guoneng Ningmei!

On August 15, the Sany Heavy Equipment JMY200 step-by-step anchor excavation and transportation machine introduced and applied by the National Energy Group Ningxia Coal Industry Company was installed and debugged in the wind lane of the 341501 comprehensive excavation face of Jinfeng Coal Mine for 13 days, marking the official use of the first anchor digging and transportation machine based on remote centralized control operation in China.

JMY200 step-by-step anchor digging machine is an innovative product of Sany Heavy Equipment in response to the intelligent development trend of the coal industry, mainly suitable for coal mine underground coal roadway, semi-coal rock roadway and soft rock roadway roadway tunneling and anchor cable bolt support operations, the whole machine is 49 meters long, weighs 146.1 tons, has the function of stepping self-moving, leveling and deviation adjustment and rapid replenishment of the fuselage, the equipment can realize continuous cutting, support, drilling, loading and transportation operations through one-button start and visual control. It replaces and solves the problem that the traditional crawler comprehensive excavator in actual operation, because of the crawler walking characteristics, causes the comprehensive excavator to be difficult to control the deflection angle and pitch angle in the process of remote centralized control cutting and walking, and the fuselage is difficult to move, and the machine position needs to be repeatedly adjusted to ensure the accuracy of the roadway construction parameters.

The commissioning of JMY200 step-by-step anchor excavation and transportation machine will greatly reduce the labor intensity of workers, effectively solve the current problems of "excavation and anchor transportation" ratio imbalance in the excavation face, and meet the development needs of intelligent mines to realize underground manpower reduction or unmanned operation.
Zhang Gang, Secretary of the Party Committee and Manager of Ningxia Coal Industry Comprehensive Excavation Service Branch, said: "We have always adhered to guiding industrial innovation with scientific and technological innovation, actively introduced and used new equipment and new processes, and comprehensively promoted industrial upgrading. In the past year, we have comprehensively promoted the introduction and use of the integrated anchor digging machine and the self-moving machine tail, covering 100% of all excavation faces, and the two excavation faces have passed the national primary intelligent acceptance. Today's remote centralized control operation of the step-by-step anchor digging and transportation machine is officially put into operation, which will further cultivate and expand the new quality productivity, truly solve the labor intensity of the operators in the difficult and complex environment of the underground, further improve the construction efficiency, reduce the number of construction personnel, reduce safety risks, and play an important role in comprehensively promoting the professional brand building of safe and efficient tunneling. ”

 
In the future, Sany Heavy Equipment will continue to be customer-centric and driven by technological innovation to provide users with more efficient, intelligent and reliable products and services.
