Abstract:In order to realize the safe and efficient production in deep underground mine, the research and application status of domestic deep mine cooling technology is analyzed, the feasibility of vaporization roadway cooling with mixed liquid in Zhaolou Coal Mine is studied. Based on the cooling capacity of the mine, the demand for the liquid oxygen and liquid nitrogen mixed liquid required for the mine is calculated and the gas produced and the equipment required are analyzed. The results show that, the vaporization roadway cooling method using liquid oxygen and liquid nitrogen, mixed at the volume ratio of 1 : 6, is feasible.
