How Does Limestone Rock Dust Prevent Coal Dust

To investigate this process in more detail, a number of ex plosion experiments using various coal dust and limestone rock dust mixes have been carried out at the Lake Lynn Experimental Mine (LLEM). These were conducted in a single entry of about 488 m (1,600 ft) in length and initiated with a methane gas explosion. A consistent set of post-

Dec 09, 2011Dec 09, 2011Underground coal mining produces finely divided coal dust that deposits throughout the mine and serves as a source of combustible material for coal dust explosions. Limestone powder, known as rock dust, is spread throughout the mine workings on a regular basis. This rock dust serves to inert the coal dust when applied in the proper proportion.

Blast Hole Drilling: The Basic Process

Aug 24, 2017Aug 24, 2017Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity.
