As a common mine support tool, the 29U steel arch support is simple and convenient to operate, and has strong support ability, but it is very prone to accidents during installation. Every worker needs to pay special attention to the following three points:

1. It should be noted that when setting up the 29U steel arch for mining, a working platform must be built at the construction site. The legs of the platform must be on the hard bottom and set firmly. A large plate with a thickness of 50mm is placed on the platform beam and connected by a tie rod. The platform must be firm and reliable;

2. When erecting the 29U steel arch for mining, the legs should be planted and stabilized first, and each section of the 29U steel arch for mining should be firmly clamped in sequence from the two gangs, and the steel bracket should be tightened before the steel bracket can be taken off the shoulder. Proceed to the next steel support operation to ensure safety;

3. When erecting 29U steel arch for mine, the steel support is transported from the ground to the work place. Before transportation, the steel support should be tied up firmly to ensure safety during transportation. Prevent the steel shed from being lost or slipped during transportation, and strictly prevent the steel shed from sliding and hurting people. When loading the vehicle, it should be lifted and taken lightly to prevent accidents.

The application of the 29U steel arch for mining at the intersection of the mining roadway has achieved remarkable results, and the choice of the U-type steel support for the mine has solved the problem of digging support. Mine U steel arch supports have more stable and reliable bearing capacity than other rigid supports, adapt to the load and deformation of soft surrounding rock, high cross-section utilization rate, convenient support support, small maintenance, high support reuse rate and reduce the use of pit wood.
