The Coal Mine Health and Safety Act of 1969 [4] recognizes roof bolting as the sole means of underground entry (roadway) support.Subsequently with the development of roof bolters with rotary drilling, roof bolting for underground coal mine entry (roadway) support took off, replacing timber supports, and soon became the sole …
Flexible tendons, or cable bolts, have been recognized as an effective and efficient support system for underground mines. In the past 10 years, use of cable bolts has increased substantially. Two of the most significant safety hazards associated with cable bolts are the dissipation of stored energy in cable coils and the failure of cable anchors.

The colonisation of A. ferrooxidans on the cable bolt wire surface in a near-neutral environment was also investigated. Specimens were prepared from a cable bolt wire and placed into the bottles containing different compounds available in underground mines, including A. ferrooxidans and geomaterials. The specimens were studied for …
"This bolt length produced an injection zone to 6 ft above the roof line when used with a standard 1.25- × 48-in. resin cartridge for anchorage," Stankus said, adding that a single cable was installed approximately every 8 ft near the center of the entry and polyurethane was then used in conjunction with the previously installed supplemental …
