A PHILOSOPHICAL VIEW ON THE TESTING OF ROCK SUPPORT FOR ROCKBURST CONDITIONS (2012)
Stacey T. R.
Physical testing of rock support for rockbursting conditions has been carried out for over 40 years. A review of this testing shows that it has been mostly component–based, rather than actually testing support systems. Further, it is concluded that none of ...

AN ANALYSIS OF FLEXURAL STRENGTH AND CRACK WIDTH FOR FIBER-REINFORCED SHOTCRETE USED IN WEAK ROCK MINES (2011)
Martin L. A.
,
Seymour J. B.
et al.
<p>To quantify the support provided by the shotcrete, flexural strength tests were conducted with two common, commercially available fiber-reinforced shotcrete (FRS) mixes using the round determinant panel (RDP) test method, ASTM C 1550. A portable RDP test ...

AN ANALYSIS OF FIBER-REINFORCED ROUND PANEL STRENGTHS AND COMPARISON TO WIRE MESH BAG STRENGTH (2010)
Martin L. A.
,
Seymour J. B.
et al.
Researchers at National Institute for Occupational Safety and Health (NIOSH) are investigating how fiber-reinforced shotcrete mix designs can be extrapolated from proven designs employing wire mesh. This paper explains the results of round determinate panel ...

AN ANALYSIS OF THE POTENTIAL OF ROOF SCREENING TO REDUCE WORKERS' COMPENSATION COSTS (2010)
Moore S. M.
,
Pollard J. P.
et al.
Each year more than 400 coal miners are injured (fatal and non-fatal) by rock falling from between or around roof supports. Many of these injuries could be prevented by the installation of roof screen (wire mesh). However, many coal mines may be reluctant ...

A NEW ROCK BOLT CONCEPT FOR UNDERGROUND EXCAVATIONS UNDER HIGH STRESS CONDITIONS (2008)
Charette F.
,
Plouffe M.
This paper presents the preliminary results of a laboratory testing program aimed at assessing the impact energy dissipation capability of a new rock bolt. The results represent the most up to date findings at this current time. In situ field tests are still ...

A NUMERICAL STUDY OF THE SHOTCRETE-ROCK INTERACTION (2008)
Malmgren L.
,
Nordlund E.
The shotcrete – rock interaction is very complex and is influenced by a number of factors. The influence of the following factors was investigated by a series of numerical analyses: the surface roughness of the opening, the rock strength and Young´s modulus, ...

AN EFFECTIVE FACE SUPPORT SYSTEM TO MINIMISE ROCKFALLS (2008)
Burger N. D. L.
,
Von Wielligh A. J.
et al.
An effective prototype face support system to minimise rockfalls in rockfall-prone mines was developed and patented during a project sponsored by the Mine Health and Safety Council (MHSC). An experimental development model (XDM) roof support unit was developed ...

CEMPAKS : STOPE AND GULLY SUPPORTS (2008)
Dison L.
,
Smith A. C. S.
The paper describes an R& D programme carried out on Cempak, a proposed stope support system for deep, tabular, hard rock gold and platinum mines; which looks in particular into the issue of convergence after attainment of peak load. Cempak fundamentally ...

DEVELOPMENT OF FAST SETTING PUMPED FOAMED CEMENT PACKS (2008)
Smart R. M.
,
Harrison A. T.
Foamed cement packs offer a viable alternative to conventional timber or other forms of packs for permanent underground support. These packs comprise steel mesh and hoop containment with an outer bag for the grout; woven, laminated polypropylene fabric being ...

FIELD OBSERVATIONS AND NUMERICAL STUDIES OF HORIZONTAL STRESS EFFECTS ON ROOF STABILITY IN U.S. LIMESTONE MINES (2008)
Esterhuizen G. S.
,
Dolinar D. R.
et al.
Limestone formations in the United States can be subject to relatively high horizontal stresses owing to the existence of tectonic loading of the limestone strata. Underground limestone mines use the room-and-pillar method, in which 12- to 18-m-wide rooms ...
