To Discuss the Directional Blasting with Recoil of Towering Constructions

Xiong Churning Zongqi Anhui University of Science and Technology (Huainan Anhui 232001)  
The article analyse the recoil phenomenon of towering constructions, which often is caused in directional blasting. And then the mechanical model for it is set up. According to the theoretical calculation, the reasonable range of blasting cut parameter on effective prevention recoil from towering constructions is determinated, and an engineering example is given at last.
