The technology of block stone extraction at complex carbonate deposits

It was found that the carbonate deposits of the Russian Platform presented mainly unconsolidated arrays with complex spatial network of endogenous vertical cracks and bedding, which is expressed in the separation column of limestone on layers and layers. Together, they define the block structure of the array. The geological structure is dominated by deposits (about 85%) of the difference between building block 0.2 m3 to 0.9 m3 with a yield of 15-25% of commodity blocks.Vsё this, together with increased demand for white stone for the construction and restoration work, placing increased demands the quality of produced and delivered to the stone-working blocks that can not be achieved using conventional methods of preparing explosives for excavation of natural array. A promising technology of nonexplosive extraction of blocks of limestone and dolomite, which provides an improvement in their quality. The technology, based on the use of a hydraulic excavator and bars installation, maximizes natural features into account hard-structural carbonate deposits. It was found that for the majority of the carbonate deposits of the Russian Platform to develop a block of limestone can be as "tailwind seizure" under the integrated use of all productive strata carbonates. To implement this technology, proposes the creation of the site of block stone extraction integrated into the working area of a large career, worked the carbonate with the formation of an array of different types of cargo flows of several raw materials. The technological solutions for the screening of the recess portions of blocks from the working area of the main pit
