Изобретение относитс к горному делу и предназначено дл проходки вертикальных шахтных стволов в сложных горногеологических услови х.The invention relates to mining and is intended for penetration of vertical shafts in difficult geological conditions.
Известны щиты дл проходки горных выработок , включающие корпус, рабочий орган (режущее опорное кольцо), рабочие полки и силовые домкраты.Known shields for excavation of mines, including the body, the working body (cutting support ring), work shelves and power jacks.
С целью предотвращени проворота щита относительно вертикальной оси корпус предлагаемого щита имеет продольные ребра, укрепленные на наружной его поверхности.In order to prevent the shield from turning relative to the vertical axis, the body of the proposed shield has longitudinal ribs mounted on its outer surface.
На чертеже изображен предлагаемый щит дл нроходки стволов в двух проекци х.The drawing shows the proposed shield for the construction of barrels in two projections.
Щит включает в себ корпус 1 с жестко прикрепленными по периметру щита продольными ребрами 2, выступающими за наружный диаметр режущего опорного кольца 3 корпуса щита на величину, определ емую физикомеханическими свойствами водоносных пород. The shield includes a housing 1 with longitudinal ribs 2 rigidly attached around the shield perimeter protruding beyond the outer diameter of the cutting support ring 3 of the shield housing by an amount determined by the physical and mechanical properties of the aquifers.
В Момент продвижени щита на забой ребра 2, имеющие на нижнем конце заостренные кромки, врезаютс в облегающую щит породу и удерживают его от проворота относительно оси ствола. Это обеспечивает стабильное положение подвесного шахтного оборудовани по отношению к щиту с сохранением проектных зазоров.At the moment of advancement of the shield to the bottomhole, the ribs 2, having pointed edges at the lower end, cut into the rock-fitting shield and keep it from turning relative to the axis of the trunk. This ensures a stable position of the suspended mine equipment in relation to the shield while maintaining the design clearances.
