Reduction of Coal Dust Concentration in the Air by Using Renewable Resources as Dust Suppressants

The aim of the study is to develop an innovative coal dust suppression agent which meets the following demands:

• Based on renewable natural resources, that have occurred as a waste product of existing industrial process,

• Meets requirements regarded to health, safety and environment,

• Is economically effective,

• Has no adverse effects on coal quality or plant and machinery,

• Suited to Latvia meeting both weather conditions and accessibility.

The aim of the study has been reached. During the study the developed suppression agents have been experimentally tested, gaining results which show that the agents analyzed may be used successfully as coal dust suppressants. The results show as well necessity of additional experiments where concentrations and quantities of agents would be determined to reach the maximum effect.
