The hardness, function and application scenario of underground mining support bolt are as follows:
Hardness:
The hardness of the underground mining support bolt will vary according to the specific design and material selection. In general, the hardness of the bolt will match the hardness of the surrounding rock. In the case of soft surrounding rock (hardness <50MPa), the anchor rod with moderate hardness may be selected; When the surrounding rock hardness is moderate (50-100MPa) or hard (hardness >100MPa), a stiffer bolt may be chosen.
Functions:
The main function of underground mining support bolt is to strengthen the supporting ability of surrounding rock and prevent the deformation and collapse of surrounding rock caused by geological stress or mining activities. It can consolidate the surrounding rock of the roadway together, so that the surrounding rock itself supports itself, so as to ensure the safety of mining work. In addition, the bolt can also control the deformation of surrounding rock, improve the stability of roadway and reduce maintenance costs.
Usage scenario:
Underground mining support bolt is widely used in various mining activities, especially in the support of underground mine roadway and underground engineering surrounding rock. In the mining process, due to complex geological conditions and poor stability of surrounding rock, supporting measures are needed to ensure the safety and stability of the roadway. At this time, as an effective support means, bolt is widely used in various mining scenarios, such as roadway excavation, stope support, chamber support and so on.
It should be noted that when selecting and using the bolt, the type, length, diameter and other parameters of the bolt need to be determined according to the specific geological conditions and mining requirements to ensure that it can effectively play a role. At the same time, it is also necessary to carry out regular inspection and maintenance of the bolt to ensure that it is in good working condition.
