▲ The equipment was successfully offline.

The total driving mileage of the extended bottom drainage roadway in the east wing of Mining Area 39 of Zhongmacun Mine is about 8.Eight kilometers，The geology is mainly limestone.，Siltstone is locally present、Mudstone section，Faced with high rock hardness、Continuous uphill and downhill、Long distance tunneling、Construction difficulties such as multiple small turns。

Offline this time“Coking coal number”（China Railway 1502）Mine Kay typeTBM，Excavation diameter is 5.03 meters，Adapt to a grade of plus or minus 18°。Aiming at the ultra-long distance tunneling of the project、Continuous large slope construction，Weak and broken surrounding rock and other working conditions，China Railway Equipment has carried out a number of targeted designs.，Can be achieved“Detective、Dig、Branch、Yun”Synchronized operation of key processes，It can effectively solve the problem of Zhongmacun Mine.“Mining imbalance”A difficult problem。Future，China Railway Equipment will continue to deepen its multi-dimensional cooperation with Henan Energy Group.，To provide high-quality equipment and high-level services for the energy industry in Henan Province，Promoting the high-quality development of mine energy development in Henan Province。
