The invention relates to the mining industry and can be used in open mining in the form of a lumpy mass building rock climbing and half-rock types.

Well-known and widely industrial applications in mining varieties of open-cast mining of rock, half-rock and earth construction rocks [1-5]. The method of mining half-rock and earth types [1] is deserted in automated mode with the surface, with the minimum volume of Stripping and separation of minerals at the elementary blocks consistent with their development of the universal mobile unit, which is carried out in an automated mode loosening of rocks each elementary block is most effective for this type of rocks by the way, mechanical, or pneumatic, or physical - implemented using complex technical devices universal mobile unit, ex-cautionous the recess conforming mineral mass and loading means rise to the surface and move in a goaf substandard mineral mass.

The main disadvantages of open mining of rocks is the separation in time and so the production space of several technological operations, a significant output of oversize and lumpy rock mass, relative low labour productivity, significant operating costs and negative economic consequences.

The closest in functionality and technical result is a method of field development rock and half-rock types raznoobraznoi patterns [6], which includes stage-detailed zoning of rocks blocking, fracture, toughness, and consumer quality and subsequent separation of the array of the working area at different height horizons and horizons or their parts - on operational units, the last - homogeneous elementary blocks, the subsequent seizure of the array dimensions and fine fractions using an appropriate set of working bodies of technical devices universal unit, which allows the direct notch overall separateness of rocks from the array, to drill and blast large separately rocks charges BB under the local shelter or to carry out their mechanical destruction or loosening and subsequent excavation and loading of the rock mass in the means of transport or the inner blade or a temporary bottom of the warehouse.

The disadvantage of this method is the lack of hierarchically deep the door is the array of rocks, the outgoing field and working on the ledges, selection of natural and natural-anthropogenic-scale and affine excavation items, based on the availability of macro - and microcracks, their strength (relative to their destructible), consumer qualities.

The technical result - improving the efficiency of field development and construction of mining-rock and half-rock type.

The technical result is achieved in that in the method of field development and construction of mining-rock and half-rock types, including automated and efficient receiving and processing Express information about the structure of the array sequentially working parts of the ledges, differentiated their selection on the basis of the received system-integrated information on multiscale structural elements of rocks with natural and induced fractures, the allocation of the received system-integrated information on multiscale structural elements of rocks includes strength, progenealogists, thermal, structural and mechanical characteristics, and automated combined destruction of structural elements includes blasting for mobile mechanized shelter and the subsequent disintegration of electrophysical way the given these characteristics, moreover, the immediate placement in temporary storage piles and shipment of the final product to the consumer is carried out after the automated supply of rock in the receiving device is a mobile screening unit with subsequent separation therein of the rock mass on the corresponding fractions by size.

Based on comparable analysis with the prototype of the differences of the proposed method lies in the complex, hierarchically deep differentiation of rocks composing the field and working on the ledges, highlighting the natural and natural-anthropogenic-scale and affine extraction elements, based on the availability of macro - and microcracks, their strength (relative to their destructible), consumer quality, as well as in the automated acquisition, development and use of multi-level information about the natural and natural-anthropogenic-scale structure of the rock. The possibility of obtaining information and forming the desired workflow allows you to solve the problem, defines novelty, industrial applicability and inventive step of the development.

The method comprises the following elements: field construction rocks rocky and half-rock type with the false natural and natural and manmade structure, due to a variety of tectonic and some other natural disturbances and anthropogenic factors - mainly the previous blasting operations; hierarchical system blocking, fixed, mainly developed in the field (career field) fractures of different material composition and the fortress of rocks; excavation items technologically relatively homogeneous within medium and large units; mobile unit and robotic technical means for the rapid and automated acquisition of geological information about the structure of the mined mineral ledge and blocks, destruction of rocks, their separate recesses, consumer sorting rock mass screening and shipment of finished products the vehicle user or as temporary warehouses.

Implement the method in the following way.

Pre-Deposit of building rocks or areas, as well as career field hierarchically divided into structurally and technologically relatively homogeneous units based on advanced operational exploration and geological forecasting. Is automated and prompt receipt and processing of Express information about the structure of the array follower what about the working parts of the ledges, differentiated their selection on the basis of the received system-integrated information on multiscale structural elements of rocks with natural and man-made fractures. The allocation of the received system-integrated information on multiscale structural elements of rocks includes strength, progenealogists, thermal, structural and mechanical characteristics. Mining blocks subdivided with substandard and temporary non-conforming building rock that destroying or blasting of holes (or holes) of small diameter (6-16 mm) under the technical shelter (shield) universal mobile units with strong and very strong rocks, or one of the mechanical methods, such as gap, using wells or bore-holes of very small diameter, medium and small fortress of rocks. Automated combined destruction of structural elements includes blasting for mobile mechanized shelter and the subsequent disintegration of electrophysical method based on the obtained characteristics. Immediate placement in temporary storage piles and shipment of the final product to the consumer is carried out after the automated supply of rock in the receiving device is a mobile screening unit is further separation therein of the rock mass on the corresponding fractions by size. Excavation excavation and sorting (screening) in the means of transport consumer conforming rock mass specific varieties produce manipulator of the same mobile unit, temporarily off-spec rock mass is placed in the internal storage, and breed in the inner or external piles.

The method allows for highly efficient field development construction rocks, deep operational differentiation construction rocks on their consumer quality, quantity, physical-mechanical and technological properties in General.
