Характер напряженно-деформированного состояния массива пород вокруг анкерных крепей

The nature of the stress and strain state of the solid mass surrounding the roof bolting

The authors describe the enclosing rock mass stress and strain state alteration patterns depending on various mining-and-geological factors. In specific operational conditions, the identified patterns will allow setting the expedient parameters of the adjoining rock bolting for higher development working stability.
