Application of Coal Fly Ash to Replace Lime in the ...

2016-7-21  Currently large quantities of lime are used for AMD control by mining companies. The manufacture of lime contributes significantly to greenhouse gas (GHG) emissions, since about 0.8 tonnes of CO 2 are generated for every tonne of lime produced. This study presents an innovative approach of using coal fly ash, a by-product from coal-fired utilities, to replace lime for AMD control in reactive mine

Coal dust explosions in underground coal mines are prevented by generous application of rock dust (usually limestone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents flame propagation by acting as a thermal inhibitor or

How Does Limestone Rock Dust Prevent Coal Dust

2012-8-30  Coal dust explosions in underground coal mines are pre­ vented by a generous application of rock dust (usually lime­ stone). If an explosion should occur, the rock dust disperses, mixes with the coal dust and prevents fl ame propagation by acting as a thermal inhibitor or heat sink. To investigate this process in more detail, a number of ex­

Method of treating coal mining refuse - IV

Sulfuric acid-containing coal mining refuse is reacted in the presence of moisture with lime, and preferably also with a pozzolanically active material such as fly ash, whereby the existing sulfuric acid is neutralized with lime and further reacted with lime and pozzolan to produce a non-polluting cementitious material, which is self-hardening at atmospheric pressure.
