摘　　要：提高立式砂仓的放砂浓度，研制了新型高压风喷嘴。通过现场工业试验证明，利用该喷嘴和调整立式砂仓内的尾砂与水的体积比等技术，能使放砂浓度达７０％～７５％，为充分发挥立式砂仓的功能找到了一条简单易行的途径。若将该技术用于其它同类矿山，将创造较大的经济效益。To improve the density of the discharged sand pulp from vertical silo,the new type high pressure air spray nozzle is developed.The pilot plant tests,in which the volume rate of tailings and water is adjusted,testify that the discharged sand pulp density from the silo can reach70%～75%It provides an easy way to improve the function of tailings silo,and will bring great economic benefit for other similar mines.
