Downhole shotcrete operation reduced from 6 to 2 people，Operator has full barrier-free remote control operation，Concrete rebound rate reduced to 10%，The annual M88 loginlabor cost saving is about 800,000 yuan...

Recently，With the successful application of "Intelligent Wet Concrete Shotcrete Robot for Mining" in Hanjiawan Coal Company，The company’s annual “Four New” technology promotion and application projects have been fully implemented。

Traditional underground concrete shotcrete support operations in coal mines are mainly manual operations，Heavy workload、High rebound rate。The company has undergone sufficient market research and field testing，Introduced “Intelligent Wet Concrete Shotcrete Robot for Mining”。

This equipment is made of mining mixer、Mining concrete pump、Composition of mining concrete auxiliary spray truck，Carrying intrusion warning、Automatic cable collection and other functional modules。After the robot is put into use，Underground tunnel shotcrete operation can automatically load materials、Stirring、Long m88 casino reviewdistance pumping and spraying，Guaranteed concrete slurry、Continuity and accuracy of conveying and spraying processes，Significantly reduce rebound rate，Improve the quality of shotcrete，Highly intelligent、Low labor intensity、High production efficiency、Characteristics such as stable and reliable quality。

Next step，Hanjiawan Coal Company will further promote the application of "four new" technologies，Adhere to science and technology to develop enterprises、Wisdom comes first，Building a solid foundation for safe production in mines。（陈国阳）
