A method for development of steep mineral deposits includes separation of part of layer to chamber stock and ceiling, driving of development workings, inclined breaking of chamber stock and discharge of those, step-by-step breaking and discharge of ceiling stock with leaving its unbroken part for formation of compensation space. Chamber ore stock is broken with inclined layers with angle equal to depositional gradient of broken overlying rocks. After that one discharges broken rock of chamber stock, and to worked-out space formed one step-by-step forcedly caves and discharges ceiling stock with overflow of overlying rocks to cavity of chamber with formation of depositional gradient of those rocks and compensation space. |
