| Abstract: | Based on the effective pressure equilibrium principle, two formulae to calculate the discharge volume and the velocity pressure power of air curtains are presented.Combining the analysis of the relative effective power formula and the experimental results,a rational range of two main parameters(K and )is given.Two formulae to calculate the air-stopping ability of multiple air curtains are presented and are verified with experimental results. According to the power-consumption saving principle,a design method for air curtain parameters is abtained.This design method has been used in some mines and operating results of the air curtains are quite good. |
