STARTING METHOD OF DOWNHOLE SOURCES OF SEISMIC VIBRATIONS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC G01V1/04 

FIELD: mining.

SUBSTANCE: proposed start-up method can be used for the sources in the construction of which there used for the start-up is hydraulic suspension accepting the weight of the device and performing the start-up in case of failure of its action. It is proposed to lower the source by means of a winch in this start-up method. The rope led from the winch through the swivel block shall be rigidly attached to upper part of movable slide of hydraulic suspension. To the rope between the swivel block there suspended by means of winch is the leading block which is attached with its rope through its swivel block to the reclaimer having limit stops in extreme positions. The rope loop from manual winch is loosely put on the reclaimer hook. The reclaimer hook shape allows retaining the rope loop of manual winch within the whole working lever turn and relieving the loop in extreme position. In order to start-up the source at the required depth, and when it is reached, the rope by means of leading block and manual winch is elongated in the section between winch and swivel block. At that, there can be continued rope slippage off the winch or the winch can be stopped by the brake. At the end of the leading block warping the rope loop from manual winch is relieved from the hook by itself and the lowering rope in the section between winch and swivel block sags. Sources and rope in the well begin falling in free falling.

EFFECT: reducing material costs during work, simplifying service and control, improving reliability and service life of the source.
