Recently，Good news came from the scene of Dananhu No.1 Mine in Hami City, Xinjiang.，Jointly built by Railway Construction Heavy Industry and State Grid Energy Hami Coal and Electricity Co., Ltd., the complete set of equipment for rapid excavation and anchoring has a maximum monthly footage of 630 meters.(Excluding the construction quantity of the reversing chamber)，The maximum footage of the subcompartment is 14m，Maximum daily footage of 28m，Refresh、It has created the highest record of roadway excavation in Xinjiang mining area.，Compared with the traditional roadheader, the efficiency is more than doubled.，It marks a historic breakthrough in the application of coal mine rapid excavation system in Xinjiang's complex geological conditions.。

Railway Construction Heavy Industry Rapid Anchor Digging Complete Equipment

This set of complete equipment for rapid excavation and anchoring was originally customized by Railway Construction Heavy Industry for the roadway conditions of Zhundong No.2 Mine of State Grid Energy Zhundong Coal and Electricity Co., Ltd.，It was transferred to Dananhu No.1 Mine in Hami City, Xinjiang in March this year.。

The roadway section width of Dananhu No.1 Coal Mine is 5.6 meters，High 3.8 meters，The ascending slope of partial fully mechanized excavation section is 15°，The roof of the working face is broken，Roof fall and spalling accidents are prone to occur.，In addition, there is water seepage in the roof、Float coal on the floor is soft，In the process of tunneling operation，It is often encountered that the excavation is affected by the equipment subsidence after the floor is cemented.，Extremely complex geological conditions on equipment reliability、Stability and security pose a severe test.。
