The invention discloses a high pierce-resistant, cutting-resistant semi-steel engineering tire and a preparation method thereof. The engineering tire comprises a tire body consisting of a plurality layers of high intensity fiber cord fabric, wherein the outside of the tire body is fixedly adhered with a tire thread made of tire thread rubber; the tire thread comprises a tire crown face and a tireside face; and a steel wire buffer layer is arranged between the tire crown face and the tire side face, and comprises two to ten layers of steel wire cord fabric. As the tire body adopts the plurality layers of high intensity fiber cord fabric, the engineering tire has high bearing capacity and high efficiency. As the buffer layer adopts the steel wire cord fabric, the tire crown has high rigidity and strong pierce-resistant performance; the tire body has little circumferential deformation during the driving of a vehicle; and the vehicle drives stably, has little rolling resistance, strong performance of passing rigid rocky mining areas and saves fuel.
