The computer program ADINA is used for the pressure analysis on the model of the underground opening, trapezoidal in shape in layers of lignite. An analysis was made before, during and after the setting of three and five anchors. The theory about pressure distribution for secondary and tertiary pressure condition in the roof and board sides of the ...

One of basic problems faced in practice of landfill waste treatment is a problem relating to landfill leachate. The intensity of their production, thus their quantity, depends on numerous factors: landfill age, waste types, microclimatic parameters and similar. This leachate must not be discharged directly into the environment without its previous ...
