DEVICE FOR FORMING OF EMERGENCY ESCAPE FROM SHALLOW MINES Russian patent published in 2015 - IPC E21F11/00 

FIELD: mining.

SUBSTANCE: invention relates to mining and can be used at emergency situations in shallow mines, for example, during underground railway construction. To excavate ground for formation of emergency escape the device contains a guiding collar with cover and fluid-powered hatch, fixed under the layer of non-passed ground on outboard supports above a railway, and the mobile transport device consists of two hingedly connected wheel bogies, on one of which the bracing frame with stoppers, hingedly fixing the housing of the power hydraulic cylinder rigidly connected to pressure transducers is placed on the spheric head of the stem of the hydraulic cylinder the sub for attachment with the hatch is hingedly fixed, on the second bogie the pumping unit and electric equipment fitted with the remote console are installed, and ensure multiple functioning on the outboard wall of the bushing installed on the second stage of the hydraulic cylinder, the slots are made.

EFFECT: decrease of time for evacuation of workers to the surface, that improves the safety of underground operations, and multiple use allows to decrease cost of fabrication; device contains railways and mobile transport vehicle with the power mechanisms, installed on it.
