METHOD OF LAYING OF WASTE CHAMBERS Russian patent published in 2009 - IPC E21F15/00 

FIELD: mining.

SUBSTANCE: invention relates to field of mining and can be used for laying of cleaning space at underground mining. Method of waste chambers' laying includes feeding into chamber of laying mixtures with different content of binding. Laying of chambers by mixtures, containing bindings, it is implemented in its bottom part up to level of top boundary of adjustment of underlying horizon, them up to mark of soil of drilling level it is implemented laying by mixtures without bindings. After shrinkage of laid massif, filtration and evaporation of water by perimetre of chamber into shrink slot it is located reinforce structure. In laid massif lengthwise chamber's walls there are driller wells up to mark, located lower top mark of laying layer in bottom part of chamber. Part of massif between chamber walls and walls of wells is destroyed. Into wells there are put in re-bars with exceeding of them over level of laid massif. And then wells and shrink slot is saturated with solution, containing bindings, after what top part of chamber it is filled with mixture with binding.

EFFECT: effectiveness increase of laying of cleaning space at underground mining.
