Aug 16, 2013 A coal dust explosion is one of the principal hazards in an underground coal mine. These mines must develop, establish and maintain an adequate and effective safety and health management system SHMS to ensure risk from such hazards is at an acceptable level. One of the primary controls against this hazard is the application of stone dust throughout mine roadways to
This chapter explains how to control dust in large-entry stone mines, including both silica dust and diesel particulate. Most stone mines are limestone mines, but a substantial minority are marble, sandstone, and granite mines. These mines differ from most others in that entry widths are 30 ft. or more and entry heights are 25 ft. or more. Such mines, developed with room- and-pillar methods, have

Feb 04, 2011 Stone dust machines were common in NSW pits, we had the small ones used in districts and a large rail mounted one used at the weekends to stonedust the main roads. Good job it did too Regarding chemicals, when I was at Wongawilli, just south of Wollongong in NSW, it was a damp to wet pit, so used water barriers spread around the pit.

Underground mining of rock releases less dust to the atmosphere because most operations are confined. However, it is more expensive and wasteful of high grade rock because pillars must be left. Less than 8 of the limestone produced is mined underground. Stone Preparation The extent of preparation given to stone received from the quarrjr depends
Stone dust, which is derived from limestone, gypsum or marble dust, increases the TIC of the roadway dust to the point where it is no longer explosible if subject to a potential ignition source Jensen and OBeirne, 1997. The addition of stone dust to the fine coal dust acts as a dilutant, heat sink and oxygengas obstruction DNRM, 2003.

Although explosion barriers used in conjunction with stone-dusting1 are thought by many to be an essential tool in the control of explosions in underground coal mines, their use is by no means ubiquitous. In the United States, for example, protection against the propagation of coal dust explosions is provided by stone-dusting alone.
Jan 15, 2021 The anti-caking treated rock dusts are as effective as non-treated rock dusts and may be most appropriate for application in areas of the mine where travel of personnel and equipment is infrequent, such as by seals and in tailgate entries. The enhanced fluidity of the rock dust when treated would enable better pneumatic transport of the rock dust.
