Description
Изобретение относится к горной промышленности и может быть использовано при разработке крутых угольных пластов.The invention relates to the mining industry and can be used in the development of steep coal seams.
Целью изобретения является снижение трудоемкости работ по перемещению пневмобаллонной крепи.The aim of the invention is to reduce the complexity of work on the movement of pneumatic bolting.
Способ осуществляют следующим образом.The method is as follows.
После каждого цикла выемки угля все секции ряда крепи разгружают и опускают до контакта секций с угольньм забоем. ЗатемAfter each cycle of coal excavation, all sections of the row of lining are unloaded and lowered until the sections come into contact with the coal face. Then
секции перемещают по угольному забою в направлении вентиляционного штрека на величину опускания крепи при перемещении ее к уголь5 ному забою. При размещении в призабойном пространстве нескольких рядов опускной пневмобаллонной крепи последующий ряд перемещается к угольному забою аналогично предыдущему, контактируя при пере мещении не с угольным забоем, а с расположенным со стороны забоя ря дом крепи.The sections are moved along the coal face in the direction of the ventilation drift by the amount of lowering the support when moving it to the coal face. When placing in the bottomhole space of several rows of downhole pneumatic support, the subsequent row moves to the coal face similarly to the previous one, contacting with the relocation not from the coal face, but from the side of the bottom support.
