THE PROBLEM OF BEDS STABILITY IN THE CONDITIONS OF UNDERMINING HIGHER DEPOSITED BEDS IN THE CONTEXT OF SELECTED AN-ALYTICAL SOLUTIONS
English abstract
Underground mining of useful mineral deposits causes changes in the virgin rock mass stress state and may affects on rock masses and mining excava-tions damages. The result of exploitation may be tremors and rockbursts. Most of-ten, in the case of deposits (of coal) exploitation, the higher lying beds are mined first. Sometimes, it is necessary to mining the lower lying bed first and undermining the upper bed. The clue is not to damage the undermined bed, and the damage raiser the distance between both beds is.
