ANALYSIS OF DISTURBED LANDS AND ENVIRONMENTALLY SAFE TECHNOLOGIES OF MINING IN PERMAFROST

ABSTRACT

The paper presents information about the mineral resource base of the Republic of Sakha (Yakutia)-one of the richest regions of Russia in minerals and severe climatic conditions of their development, the presence of almost universal permafrost causes a particular vulnerability of the environment in mining. In this regard, the methods and results of studies of the geoecological state of the landscape in the development of Geosciences, including space surveys of mining operations, the regime of their restoration by natural means, and the main directions of reclamation of disturbed lands are analyzed.
New technologies of mining operations associated with the simultaneous reclamation of disturbed lands, which initially reduces the area of violation by much reducing the cost of their reclamation, have a particular interest. The assessment of the degree of land disturbance by mining operations was carried out by laser scanning, which significantly reduced the complexity of the work, increased the accuracy of measurements and contributed to the development of rational technological solutions for the reclamation of disturbed lands.

Keywords: northeast of Russia, permafrost, disturbance by mining operations, laser scanning, ecologically safe technologies.
