Improvement of methods of accounting for increased losses and dilution of minerals during production

The article describes the methodological approaches to accounting and valuation losses of minerals during open development of deposits with complex mining and geological conditions. As an example, analyzes indicators of losses of minerals during the development phase of plot Kostonaiskogo Chanvinskogo deposits of limestone used for the production of caustic soda. The installed actual level losses exceeding 30% of the total production volume of raw materials. The given reasons of increased losses of limestone in comparison with in the project losses. Installed that with a detailed exploration of the array of limestone was not identified zone karst and zone with high clay content lying in the form of “lived” in zones of high fracturing. In the result of blasting is the mixing of karst explode, clogged areas with pure limestone, its pollution to exceed the allowable values, which leads to loss of balance reserves of minerals during extraction. The article gives recommendations for calculating the level of losses during the when developing complex faces, which are characterized by intermittency breed productive layer of limestone and karst zones.

Keywords: limestone, operating losses of limestone, Chanvinskoe deposit of limestone, contamination, dilution, karst zone, methodology, valuation losses.
