Rockfill material blasting grade prediction method for water-power engineering

Abstract

The invention discloses a rockfill material blasting grade prediction method for the water-power engineering. The rockfill material blasting grade prediction method includes: acquiring location information and azimuth information of a joint by adoption of a suitable joint investigation method or means according to an engineering specific stage and a site condition; picking up a rock sample on site, producing the rock into a test piece meeting the split Hopkinson pressure bar test demand, and measuring a parameter of the rock through the indoor statics and the split Hopkinson pressure bar test; selecting a suitable rock and explosive model and a simulation tool, performing treatment on the measured rock parameter to obtain a simulation parameter, and performing blasting crack simulation to obtain the range and the number of crack propagation; establishing an after-blasting joint rock model according to rock primary joint information and a blasting crack propagation result obtained from site investigation; and calculating out the blasting grade according to data of a blasted joint rock. The devices and the processing method adopted by the method are simple, can be applied to an engineering site, and can be optimized with change of software and hardware.

AI Technical Summary

Benefits of technology

The technology described has several benefits compared to previous methods that were simpler but still valid for use on projects or connections between different stages. It also allows for efficient implementation across multiple technologies without changing any details about how it works.

Problems solved by technology

The technical problem addressed during exploration work at various locations around China involves finding adequate filler stones needed for building up hydroelectric power plants (HIP) underground reserves. Existing techniques involve excavating ground layers containing hardened cobbles called clay blocks, which causes difficulties in achieving proper placement within these regions while ensuring efficient use of resources. There exists no effective way to determine whether sufficient filler needs exist between different types of natural deposits like bauxite and sandstone.
