Underground roof support is one of the main support forms for underground engineering and rock slopes. It plays an important role in the maintenance of civil engineering stability, especially in jointed and fractured rock masses. Underground roof supports are used to strengthen the rock mass. It's very obvious.
The underground roof support is usually cold rolled. Its specifications and technical parameters have not yet constituted national standards. It is usually based on consumer demand or customer needs to manufacture corresponding molds (rolls) and install them on the rolling mill to form iron coils. U-shaped steel that requires specifications. Underground well roof supports have good mechanical properties, so they are widely used in mechanical engineering.
Underground roof support is a basic component of roadway support in contemporary coal mines. Underground shaft roof supports tie the surrounding rock of the roadway together, so that the surrounding rock itself supports itself. The underground roof support structure is reasonable and the pre-tightening force is large. It can automatically adjust the force direction, increase the binding force on the surrounding rock, and realize mechanized and fast installation.
