【 摘 要 】

In order to study the shielding performance of lead-zinc tailings mortar, a lead-zinc tailings mortar with different contents of tailings sand (0%, 20%, 40%, 60%, 80%, 100%) was prepared. The mass attenuation coefficient in the energy range of 1keV-100GeV is calculated by XCOM theory. The test results show that with the increase of tailings sand content, the mass attenuation coefficient of mortar increases gradually, and the shielding performance is better. The simulated value and experimental value have Good consistency; the mortar strength prepared with lead-zinc tailings will decrease with the increase of tailings sand content, and the amplitude is larger.
