Stability Design of Open Pit Walls Using 3D Modelling Approach (2020)

The open pit mine is part of a Greenfield exploration project. Itasca Consultants GmbH in cooperation with Itasca Chile were contracted to develop a stability design of the pit. The analysis has been performed using Itasca’s three-dimensional distinct element code, 3DEC (Itasca, 2016).

Influence of former near-surface ore mining on a road construction project (2020)

The road construction department of the district of Steinfurt, a district in the north of the coal mining area in the Ruhr region, is planning the construction of the new road K 24n. The road axis runs through an area partly affected by old mining operations.

Interaction of old near surface coal mining and a road construction project (2020)

The new connecting road K 24n is to be built in the most northern expanses of the coal mining area in the Ruhr region. The road axis runs through an area partly affected by old surface near mining operations. The coal is located in two seams, both dipping north with an angle of approx. 11°. These seams have been mined by three potential drifts, which have been identified by a geophysical field study.

Numerical simulations of shield support for a coal mine (2019)

The development and mining of a deeper seam in a coal mine, located in southern Siberia is planned. ITASCA was tasked with assessing the minimum support pressure and maximum unsupported distance between shield and coal face required to ensure stability of the roof. Also the stress state, displacement field and excavation damaged zone in the roof of the seam were analyzed.
