Recently，Good news from Ningtiaota Coal Mine of Shaanxi Coal Group，China Railway Equipment GroupEJM315/4-2FIntelligent Rapid Tunneling Equipment CreatedLow power and short type（Cutting motor power 315kw）Digging and anchoring integrated machine semi-coal and rock roadwayMaximum daily footage of 32m，Monthly footage of more than 800 metersFootage record。

This equipment is aimed at the actual working conditions of Caragana mining industry.，Intelligent rapid tunneling equipment for optimization and upgrading，Organic combination of tunneling and anchoring synchronous operation，Can realize the integration of digging and supporting、Anchor digging synchronization、Full face support、Continuous transport、High efficiency dust removal、Flexible transition、Automatic cutting and other functions，And that difficulty of coal mine excavation replacement is sol.、The problem of mining imbalance，Avoid manual handling、Drilling、Manual pre-tightening and other operations，And that labor intensity is reduce，And improve that operation efficiency.，Driving speed can be increased by 2-3 times，The number of tunneling workers can be controlled within 10.，Promote fewer people in coal mines、Unmanned construction。

The equipment has successfully completed the first stage of excavation task in Ningtiaota Coal Mine.，Upgraded by China Railway Equipment，Continue to be used for development and excavation of Ningtiaota Coal Mine。During site assembly and commissioning，Front-line service experts formulate targeted improvement measures，Collaborate with customers，Successfully completed the underground installation and commissioning work，Lay a solid foundation for that rapid tunneling construction of the dig and anchoring integrated machine。

In order to make the customer's front-line personnel master the equipment operation skillfully,，The company has adopted various forms of training.，In addition to face-to-face teaching、In addition to hand-in-hand training，Also through on-site practice、Joint discussion, etc.，Starting from the basic structure and working principle of the equipment，The operation process and precautions of the equipment are explained in detail.，It also combines with practical cases.，Analyze the problems that may occur during the operation of the equipment and the solutions。

China Railway Equipment Group has accumulated rich technical experience in the construction of hundreds of underground projects.，Difficulties in coal mine roadway excavation，Strengthen scientific research and tackle key problems，Innovative process and method，Successfully developed with independent intellectual property rightsEJMFull-series digging and anchoring integrated machine。Future，China Railway Equipment will continue to strengthen the development of mining equipment products and technological innovation.，With leading technology and intelligence、Unmanned products，Better serve the development of new quality productivity in mine construction。
