The hazard presented by geological disturbance zones when intersected by underground mine roadways in the Donbass is assessed. Tests were performed in two Donbass mines to establish the degree of stress relaxation of the seam in the face area. Measurements were also made of the proportion by vol. of helium in gas samples from disturbace zones.

· Geology was found to be three times more important than the rainfall regime in explaining the total variation in deciduousness. The four substrates differed in soil properties, with higher fertility and waterholding capacity on metamorphic and basic rocks than on sandstone and alluvium. The increase in forest deciduousness was stronger on the substrates that formed .

· Advances in drilling and blasting affect energy consumption overall in the mine, for example, you can recover more material with the same amount of energy at the crusher. If fragmentation is correct, it will end recycling material through crushers. And with extremely hard rock, teams will know to blend it so performance and recovery remain high."
