Physical properties and qualitative characteristics of sands from the Volodin Kamen deposit

   The article presents the industries where sand is an indispensable raw material. Information about the deposits in the region is provided.

   The purpose of the work is to determine the physical properties and qualitative characteristics of the useful strata.

   The geological structure and hydrogeological conditions of the Volodin Kamen deposit are considered in detail. The complexity of the geological structure of the quarry field is assessed. The useful deposit, overburden and underlying rocks are described. The qualitative characteristics of the mineral are given based on the results of geological exploration. The quality of sand is assessed according to the requirements of GOST 8736-2014 “Sand for Construction Work”. The results of determining the granulometric composition, true density, filtration coefficient, angle of repose, and potential reactivity are performed and presented. According to the size, unsustained thickness of the useful strata and the quality of raw materials, the deposit is assigned to group 2. A radiation and hygienic assessment was carried out to determine the suitability of natural sand for industrial development. Continuous gamma logging of wells with point registration (every 1 m) was carried out using the SRP-68-01 No. 373 device. The radioactivity of the rocks of the Volodin Kamen deposit varies from 5.0 to 7.0 μR/hour (the norm is 48 μR/hour), which is significantly less than the requirements of NRB 99/2009 SanPiN 2.6.1.2523-09, therefore it belongs to class 1 of building materials, and they can be used in construction without restrictions. According to the deposit, the quality of natural sand meets the requirements of GOST 8736-2014 “Sand for construction work” and it can be used for the construction of foundations and coatings of highways.
