Mine roof bolt system |
| 摘要 |
This new system can utilize a threaded bolt head on one end of a roof bolt and an anchoring device on the other end of the bolt. The roof bolt is designed in such a manner to allow the bolt head to drive the bolt for anchoring purposes and to allow the bolt head to also serve as the attachment mechanism for ancillary appendages. This system can be utilized as the primary roof bolting system, or, as an ancillary system in conjunction with existing primary roof bolts. |
