Изобретение относитс  к геофизическим Способам изучени  горного давлени  и может сыть использовано дл  контрол  за напр женным состо нием горных пород. Способ может примен тьс  при исследовани х напр женного состо ни  горных пород в горных выработках , при исследовании поверхности шахтных полей, прочности кровли искусственных и естественных полостей в горных породах , при инженерно-геологических изыскани х под строительство наземных и подземных сооружений.This invention relates to geophysical methods for studying rock pressure and can be used to monitor the stressed state of rocks. The method can be applied in studies of the stress state of rocks in mine workings, in the study of the surface of mine fields, the strength of the roof of artificial and natural cavities in rocks, in engineering and geological exploration for the construction of surface and underground structures.

Известен способ эманационной съемки, основанный на отборе проб из шпуров дл  геологического картировани  1. Однако этот Способ не позвол ет оценить динамику изменени  напр женного состо ни  горных пород в зоне вли ни  выработок или полостей в горных породах.The known method of emanation survey is based on sampling from holes for geological mapping 1. However, this method does not allow one to estimate the dynamics of changes in the stress state of rocks in the zone of influence of workings or cavities in rocks.

Известен способ контрол  напр женного состо ни  угольного массива в зоне вли ни  очистного забо , заключающийс  в бурении скважин или шпуров, периодическом отборе газовоздушных проб, измерении концентрации метана, оценке изменени  напр женного состо ни  массива впереди забо  и оценке измерени  напр женного состо ни  массива впереди забо  по характеру изменени  газовыделени  из скважин 2.The known method of controlling the stress state of a coal mass in the zone of influence of the clearing downhole consists in drilling wells or holes, periodically taking gas-air samples, measuring the concentration of methane, estimating changes in the stress state of the array ahead of the slab, and estimating the measurement of the stress state of the array ahead by the nature of the change in gas emission from wells 2.

Этому способу контрол  напр женного состо ни  горных пород присущи недостатки; область при.менени  ограничена (в основном, на угольных месторождени х); точность способа недостаточно высока , поскольку процесс истечени  из пласта сорбируемого газа и его объемы измен ютс  не только от напр женного состо ни  горных пород, но и других факторов.This method of controlling the stressed state of rocks has disadvantages; area of change is limited (mainly in coal deposits); The accuracy of the method is not high enough, since the process of outflow of the sorbed gas from the reservoir and its volumes vary not only due to the stress state of the rocks, but also to other factors.

By varying the concentration of gas of radiogenic origin, for example, radon, toron, gels, in the well functioning in the zone of influence of mining, the stress state of the massif is estimated, and by its increase the time of the destructive influence of the reference pressure on the rock mass is estimated.
