FIELD: mining.
SUBSTANCE: invention relates to mining, namely to drilling and blasting operations in rocks, and can be used in various industries, which use blasting operations in rock massifs, in particular, in development of minerals by open method. Suspension well stem includes supporting structure exceeding diameter of wellhead and dimensions of suspended part fixed thereon by flexible link. Suspended part is made in the form of a pointed cylinder, the diameter of which is commensurable with the diameter of the well. Cylinder is composed of flexible resilient plates the length and width of which are proportional. Plates are connected by constant link.
EFFECT: design of the device increases efficiency of well screening.
