| description | The relevance of the study is caused by the need to improve geophysical methods for monitoring the stress state and forecasting geodynamic phenomena in the mines of Kuzbass, including geodynamic control systems and geo-location.
The main aim is to substantiate rational methods for measuring electromagnetic radiation parameters in conditions of intensive mechanized mining of coal seams and to establish criteria values of these parameters for local prediction of impact hazard based on comparison with the main geomechanical parameters (stress concentration coefficient and distance from the coal mining contour to their maximum point) obtained using the direct basic method of drilling fines extraction.
Objects: mine workings of purifying lava purification on the Kirov coalmine and when sinking preparatory workings on the coalmine Esaulskaya.
Methods: analysis of scientific and practical results obtained by the electromagnetic radiation methos, which experimental and theoretical bases have been developed in different organizatons.
Results. The interrelation of the amplitude, shape, pulse repetition frequency, intervals between them with the stress level, crack opening, and the rate of their development is established. «The Angel» hardware complex was developed and is constantly being improved. Its complex tests were carried out at a number of ore and coal deposits. Based on the results of industrial experimental studies the authors proved the possibility of using the method and equipment for recording electromagnetic radiation for solving a wide range of engineering and geological tasks related to geological underground exploration, diagnosing zones of tectonic disturbances, displacements and deformations. The relationship of the electromagnetic radiation parameters with the stress concentration in the array and the distance to their maximum was experimentally proved, and the features of the dynamics of changes in these parameters over time were established. Criteria values are established and a nomogram is proposed for the local prediction of impact hazard in the treatment and preparatory workings of Kuzbass mines. |
