With the rapid development of modern science and technology, remote sensing geological survey theory based on what is built on the interaction mechanism the physics of electromagnetic radiation and geological body. It is through the multi-wave spectrum (light), more than reality, multi-imaging, multi-polarization, multi-level enhancement processing technical means to collect and analyze remote sensing data in order to get more spectral, space geological information than alteration mapping. Remote sensing geological survey does not require direct contact with the target, but use of visible light, infrared, microwave detection instrument, through photography or scanning mode, the induction of electromagnetic radiation energy, transmission and processing, thereby identifying the surface target from a long-range, high-altitude and even outer space platforms.

Abstract Briquette hammer fracturing experiments were conducted with different impact energies and molding pressures to investigate the characteristics of the electromagnetic signals. The response pattern of the electromagnetic radiation energy as a function of the impact energy and the coal firmness during impact fracturing of a coal mass were analyzed. The characteristics of the electromagnetic radiation signals during the uniaxial compression fracture of a coal mass were also used to analyze their source during fracture. The results show that the generation of electromagnetic radiation during coal mass fracturing can be divided into three stages: compaction, crack propagation and sliding friction. Electromagnetic energy is mainly radiated during the sliding friction stage. The electromagnetic radiation during briquette hammer fracturing is characterized by a frequency below 2000 Hz, an amplitude in the range from 0.05 to 0.6 mV, and a total energy on the order of ∼10−14–10−10 J. For coal masses with the same firmness, as the impact energy increases, the total energy of the electromagnetic radiation increases. For the same impact energy, as the firmness of the coal mass increases, the total energy of the electromagnetic radiation first increases and then decreases.

The investigations of stochastization mechanisms of distributed dynamical systems (DDS) are developed not so complete as stochastization of dynamical systems with concentrated parameters (CDS). Therefore the corresponding DDS which is close (in one or other sense) to the CDS under consideration is used. Such substitution means some roughening of an initial problem. However, there are such important stochastization mechanisms understanding properties, which are connected with system “distributivity” on principle. In this paper the conception of a proximity to the CDS is introduced for one particular class of the DDS. It is shown that such kind of systems has two stochastization mechanisms, one of which is common to the DDS and the corresponding CDS. Another stochastization mechanism inherent in DDS disappears under transition from DDS to CDS.Distributed dynamical system considered below is not abstract but describes the set of concrete physical devices, for example, microwave oscillators. It may be devices in which kinetic energy of an accelerated electron beam is transformed into electromagnetic radiation energy, or oscillators with delayed feedback.
