Self into the hollow bolt as the research object, pneumatic bolt Fault characteristics and analyze the reasons for the failure, proposed to solve such failure approach, pneumatic bolting machine maintenance and repair process to identify and provide practical the practical basis.
In the field of coal production, the self into the hollow bolt support in improving the supporting effect, reduce costs and speed up the tunneling speed and reduce the amount of auxiliary transport, reduce labor intensity and improve roadway utilization has a very prominent location sex, with universal application roadway bolting technology, pneumatic bolt machine has become an essential roadway bolting equipment, it has a light weight, easy to move, simple operation, easy maintenance, high drilling efficiency, at the same set of drilling, stirring, installation bolt, cable in one, it is the roof hardness <F8 various rock roadway coal Lane, semi-coal roadway to anchor retaining jobs ideal choice, it is widely used. With the rapid development of roadway bolt support, pneumatic bolting machine safe and reliable operation of increasingly high demands. Visible, pneumatic bolt the safe operation of the machine is closely related to the development of the roadway bolt support, maintenance and repair of essential self into the hollow bolt.
