Abstract：In order to explore the application effect of bentonite-based disaster control materials in different coal mine disaster scen-arios,we modify and study gas borehole liquid sealing materials to realize full cycle thixotropic sealing of new fissures,composite bentonite fire preventing and extinguishing materials with high water retention and strong oxygen isolation,anti-agglomeration-crust powder explosion suppression materials with good dispersion and not easy to caking in high humid environment,the thermal insula-tion material for deep well roadway with low thermal conductivity,strong adsorption and small rebound capacity,and the improved adsorption mine toxic gas purification material with enhanced porosity All these materials are carried out in engineering application practice.The results show that the modified bentonite material has good disaster control effect and has gained outstanding applica-tion value in coal mine disaster control.
