Estimation of stability permafrost rocks against technogenic attack during mastering the north territory of Russia

In this work is presented method drawn near accounting estimation of the influence technogenic factors on geocryologycal conditions and possibility of the begining disturbance of permafrost rocks. The Discriminating devil of the proposed method is a possibility of its using for a small area of heat technogenic attack with the different form and under flaky construction in top strata of the rocks.
