Improved Soil Stabilization by Geoelectrical Water Content Determination and Statistical Shear Strength Models

Autor: Petri Valasti

Publikováno v: Journal of Environmental and Engineering Geophysics. 15:233-241

This article addresses one approach that could be used for automating a soil stabilization system. Instead of manually guiding the injection of a binding agent, a scheme is introduced where pre-determined subsurface conditions of the target volume wi

3D Seismic Surveying in Kevitsa Open Pit Mine

Autor: Petri Valasti, Alireza Malehmir, Chris Wijns

Publikováno v: ASEG Extended Abstracts. 2012:1-3

3D reflection seismic survey was conducted over an area of about 9 km2 at the Kevitsa Ni-Cu-PGE (platinum group elements) deposit, northern Finland. About 1000 active receivers and 3000 shots in nine overlapping swaths were used to acquire the data.

3D reflection seismic investigation for mine planning and exploration in the Kevitsa Ni‐Cu‐PGE deposit, northern Finland

Autor: Pekka Heikkinen, Emilia Anna-Liisa Koivisto, Milovan Urosevic, Christopher Juhlin, Chris Wijns, Ilmo Kukkonen, Alireza Malehmir, Markku Paananen, Petri Valasti

Publikováno v: SEG Technical Program Expanded Abstracts 2011.

A 3D reflection seismic survey was conducted over an area of about 9 km2 at the Kevitsa Ni-Cu-PGE platinum group elements deposit, northern Finland. The principal objective of the survey was to image major fault and fracture zones at depth. Understan
