摘要： A method of synchronization of the seismic and seismo-acoustic measurement networks, in particular intrinsically safe mine networks is characterized in that in each transmission channel a measurement of time correction (2Ki) of signal propagation from the receiver (OD) to the transmitter (ND) and back is periodically initiated. Then in the receiver (OD) phase-locked loop comprising a real time clock (RT), shifted second internal reference tact (TWa) is generated as a correction in the continuous mode, shifted forward of the time correction (Ki) in phase relative to the second reference tact (TW) from a clock (GPS) with simultaneous forward shift of the internal time clock (RT) by the time correction (Ki). Besides, in a continuous mode, the internal synchronizing tact (TSa) is generated (N) times, preferably 250 times more often, with forward shift of correction time (Ki) in phase, relative to the second reference tact (TW), keying the output of supplying-separating inverter (PZ), intrinsically safely providing power to the teletransmission line (TR). The system designed for this method contains in a linear block (BL) of a receiver (OD) a semiconductor key (KL) of the receiver (OD) shorting a teletransmission line (TR), connected via an input transoptor galvanic seperator (SG2) of the linear block (BL) to the output (b) of the microcontroller (MK). In a transmitter (ND) a forming block (UF) of synchronizing tact (TS) is connected via a capacitor (C) to a transmitter linear block (BLN). The output of the forming block (UF) is connected to one of the inputs of a phase detector (DFN) of the microcontroller of the transmitter (MKN). The transmitter linear block (BLN) contains the transoptor galvanic separators (SG3 and SG4) of signals.

摘要： A method of detecting and reducing methane hazard in the longwall area is characterized in that the regions of stress (N) concentration are periodically localized on the longwall panel length by a passive velocity tomography using seismometers (8) and low-frequency geophones (9). These data are compared with current seismoacoustic measurements localizing places (M) of groups of crashes accompanying cracking of the rock mass in the longwall panel length, with measurements of methane concentration and the air flow in the working. The places of stress (N) concentration in front of the longwall are additionally localized with an active attenuation-damping tomography taking into account a shearer (13) position relative to the working (B). Then, these variables are correlated in time and space, and after finding that the correlation coefficient exceeds predetermined critical value, preventive procedures to minimize methane hazard are initiated. In the measurement system the seismic recording system (1), methanometric system (3), executive system (6), and warning module (7) are connected to the microprocessor analytical system (5). The seismic recording system (1) with attached at least four seismometers (8), at least four low-frequency geophones (9) and at least two strain sensors (10), is connected to the seismoacoustic recording system (2) with at least four geophones (11), and to the position and operation control system (4) of the shearer (13) with a shearer position sensor (12).
