Introduction

The January 2007 Mining Magazine has a comprehensive article on Scaling to Shotcrete. An electronic version of the magazine is available on their site, but it is so big a file that even my powerful computer took longer than I had patience to wait trying to download it. Their article notes that scaling if the first approach to control of falling rock in underground mines, but this must be augmented by rockbolting and shotcreting. Here are some links to web resources on the topic.


Definitions

InfoMine Dictionary Gunite that commonly includes coarse aggregate (up to 2 cm).

Wikipedia Shotcrete is mortar or concrete conveyed through a hose and pneumatically projected at high velocity onto a surface. Shotcrete undergoes placement and compaction at the same time due to the force with which it is projected from the nozzle. It can be impacted onto any type or shape of surface, including vertical or overhead areas.


Societies

I did not find a society of mine shotcreting. But here are a few sites of general interest on the topic or related.:


Short Journal Articles

The InfoMine Library has many papers on shotcreting in underground mines. The following is a list of short articles, maybe really occasional pieces that are not, in my opinion, substantive enough to include in InfoMine library, but they are sufficiently interesting to list below:


Heat Abatement

Apparently shotcrete may be used to insulate mine environments from hot rocks in deep mines. Here is a paper that explains how: An Insulating Shotcrete for Heat Abatement in Deep Mine


Case Histories

Here are a few case studies on shotcrete use in mine applications.


Suppliers

Mining magazine states that there are only six companies with a comprehensive capability in shotcreting equipment, defined as the complete carrier vehicle and pumping and delivery systems. The magazines list the six as: Normet, Jacon Industries, Andersens Mek Versted, Sika, Shotcrete Technologies, UGC International (BASF) Meyco.

InfoMine lists many other shotcrete suppliers in the Buyer’s Guide.
