The receiving chamber 1 through the hole | 0 communicates with the cavity between the tube 4 AND the drill rod 5. The device works as follows, . , -,.:. -. ./.h ,. .,. . i;., .. ,, „...“. . ,,.,. / „. A receiving chamber 1 with a valve 2 is mounted at the wellhead. With the aid of the drill rod 5 and the rock-breaking crown 6, the well is drilled to the quicksand, then the crown is extracted and through the drill stand is made from the well casing using a manipulator (drawing; e is not shown). An elastic sealing ring 7 is mounted on the first casing. Between the receiving chamber 1 and the lower casing pipe 4, an elastic ring 3 is installed, and the float is opened. In the powerful flow of the flow valve, the valve 2 is shut off and drilling is performed when it is completely shut off. After drilling the curtain and overlapping it with casing 4, phenile 2 is fixed and the sealing ring 3 moves upwards beyond the valve 2. Формула изобретени  Устройство дл  проходки восстающих выработок , включающее буровую колонну с породоразрушающей коронкой, обсадную трубу, уплотнительное кольцо между буровой колонной и обсадной трубой, отличающеес  rw, что, с целью повышени  безопасности работ при возможном пересечении плывуна , оно снабжено дополнительной трубой и уплотнйтельным кольцом, установленны-ми в устье проходимой БЬ1работки и образующими совместно с обсадной трубой приемную камеру, полость которой сообщена с полостью, образованной между буровой колонной и обсадной трубой, причем приемна  камера имеет выпускной вентиль.
