Pilipenko J. Development of method and means of a control structural disturbance of a body, which are based on the effects, caused polarization of rocks

Item of studies - phenomen of an electrization in the tight structurally disturbed rock mass. The purpose of studies: to elaborate a method and facilities of an effective control of a structural disturbance of a massif basing on filing of transient phenomena of the aroused polarization of rocks in variable electric fields boosting selfdescriptiveness and veracity of diagnostic of a state and properties of a rock mass. Methods of studies: in operation the all-up method of studies including analysis and generalizing of minings in the given field of science and engineering, analytical investigations basing on methods of classic electrodynamics utilised; laboratory and mine geophysical experimental researches with usage industrial and prototypes of instrumentation.Dissertation is devoted to researches of the phenomena of mining rocks elutriation and development on base dependences of method and means of control of structural disturbance and tensely-deformed state of body. Certain electro-physical descriptions of row of mining rocks variety are presented. Nature and character of transitional descriptions dependence caused polarization of rocks from their presence of cracks in body and the tensely-deformed state have been analyzed. Certain basic informing parameters of method of structural disturbance control of a body, which is based on the effects caused polarization of rocks, were determined. Methodical bases of diagnostics of structural disturbance of mining rocks by electrometric method concerning to the ore and coal deposits, which include the order of implementation of works, treatment and interpretations of results and reflections of information are developed. Facilities of method realization are developed in mine and field conditions. Making a decision of concrete production tasks it was executed the verification of develops efficiency. Materials were entered in some normatively-technical documents, adopted on the mining enterprises of ore and coal industries. Novelty. Regularities of variation of the performances of transient phenomenons of the aroused polarization of rocks, ores and coals from arguments of fracturing of a massif for the first time are established; intercoupling of transient phenomena of the aroused polarization with tight - strained state of a rock mass for the first time is installed, for an estimation which one the method of the aroused polarization proposes coefficients of mechanical-electrical connection and electromechanodestruction; the further progressing was received by(with) studies of influencing of the factors reshaping pattern of a massif and effects of aroused polarization of rocks, the physical and mathematical model which is taking into account electrodynamics of interplay of electric charges with elements of structural disturbance is proposed that it is necessary in a basis of a designed method of verification of a structural disturbance of a massif. An extent of an intrusion. The actual economic benefit of an intrusion of minings has compounded more than 297 thousand rbl. and 64 thousand grn. ). Field of usage. The modes are designed and the means of diagnostic of a state of a massif permitting to accept effective technological solutions at management of mining operations in a band of a structural disturbance, in particular are built, to use by looking up of near-surface cavities, check of progressing of deformation processes in bands of tectonic disturbances, estimation(rate) of geometrical arguments of a structural disturbance and geomechanical state of bench coals at transferring of discontunities by mining operations.
