Issue Construals and Corporate Water Stewardship

Business Strategy and the Environment, EarlyView.
ABSTRACT In the face of mounting environmental and social pressures, the importance of responsible corporate water stewardship (CWS) should be evident, yet not all businesses are taking water management issues seriously. The aim of this study is to explore why differences in CWS persist, especially within industries facing similar resource challenges ...

Combined method of opencast and underground mining of valuable ore

E3S Web of Conferences, 2018
The efficiency of the combined opencast and underground mining of deposits directly depends on the overburden amount within the open pit boundaries. The amount of overburden to be removed, in its turn, is determined by the angles of the open pit slopes ...
