Method for prevention and control of spontaneous

Sep 01, 2017 Mechanism of coal seam spontaneous combustion is as same as that of a general spontaneous combustion, which will require oxygen. The oxygen, provided by air leakage, is influenced by extraction and other human activities .Meanwhile, fire extinguishment for coal seam spontaneous combustion is quite difficult as it is not easy to remove such a huge amount of heat.

Coal gangue (CG) is a mixture of organic and inorganic compounds and mineral materials,that are fused together with coal deposits during the coal formation process .CG is a complex industrial solid waste generated from the coal mining and washing process .Because of long-term stacking, spontaneous combustion frequently occurs in coal and carbonaceous materials ; this

Research on complex air leakage method to prevent coal

Mar 01, 2019 Spontaneous combustion of coal is one of the major hazards threatening production safety during longwall mining. Mining-induced voids, which provide passages for air leakage, are the key factor triggering spontaneous combustion of coal in longwall goafs. In this study, a comprehensive method, which combined pressure balance, grouting injection, and filling fissures, was proposed to prevent
