The process of diamond explosive mining in kimberlite rocks was modeled at a concrete block containing quartz plates. The products of explosion including fragments of quartz were studied by the small-angle x-ray scattering (SAXS) technique using the Cu Kα1 wavelength. The typical sizes of domains in the samples are estimated as 200–220 nm. The increment of grain sizes versus the initial distance between a considered fragment and the explosion center is observed. The superlattice interplanar distances are approximately determined as 80–100 nm and 300–500 nm. The presence of components with a chain-like geometry in the samples is stated. The assumption of domain borders formed by dislocation walls within the samples is formulated
